2012 jeep liberty No Heat problem, diagnostic 

Joshua, this video saved my butt. Watched and rewatched a couple times then went out and pulled the actuator off. It was stuck. Cycled the door a few times by hand to make sure it was free then put the actuator back on. Now I have hot and cold back. Thanks!

You did the perfect test as far as I am concerned. You took the actuator off and you were able to move the "flapper door" which showed nothing was stuck OR, when you took the actuator off, you were able to "un-stick the flapper door". Then you put the actuator back on and saw that when you turned the dial, the gears moved again and all is well. I have done it one step earlier I have to admit, I have the actuator NOT mounted, but I plugged it i,started the vehicle and turned the heat dial and watched for the actuator to move. You just have to make sure that when you remove the actuator and when you reinstall the actuator, the temperature was at the same setting both times. They usually come from the factory in the "cold" setting, which is the "fail safe" for the unit. You can check the flapper door is in the cold position by starting the vehicle, get it up to temp and when the blower is running, turn the flapper so only cold air flows out. By the way, this video is one of the BEST because you don't talk and talk and talk and give us all KINDS of information that is not relevant to anything concerning why we are watching the video!

Hello, nice video. The 2008-2012 Liberties are all the same with these. They all have three (3) actuators. 2 on the driver side and 1 on the passenger side. 1. Driver lower side - Blend door actuator (heat/cool). 2. Driver upper side - Mode actuator (vent, heat, defrost, etc). 3. Passenger (left of glove box, easiest way is to remove glove box: open glove box, slide to right, pull out) - Recirculate actuator (fresh air/recirculate). Hope this info helps someone also!

This was a huge $ saver. Was a little chilly this past week at night and the windows were fogging up. Tried to put on a little heat and it was nothing but cold air. I looked and saw the Actuator wasn't moving so i got one off Amazon. Was about $13 cheaper than my local parts store. Since i wasn't in any rush i decided to get it online and wait the 2 days for shipping. It took about 10-15 minutes to replace and I now have great heat again. The only thing i had to do was plug it in and move the knob until it lined up with the old one. I was then able to put it back into place and screw it in. Such an easy job too.

THANK YOU!!! You saved me hundreds of dollars. I was about to take my 2012 Jeep Liberty to the mechanic when I stumbled upon this video. I replaced the actuator and all is well. Great diagnostic info too!

Man thanks a bunch brother. You saved me from this freezing winter in Chicago. Now I know exactly how to diagnose and repair it.

Great video! You saved me $$$ by clearly walking me through trouble shooting and an easy repair. Keep up the great info sharing!

Thanks so much for this! Had no heat and was able to determine it was a sticky actuator that just needed some unsticking. Saved me tons of money!!

Thanks for making this video, man. I was wondering if I was gonna have to rip the whole dashboard out and I am so thankful you showed us all how easy this fix is!

Thanks so much for this video, wife's liberty had the same exact issue. Absolutely a life saver, thanks for taking the time to make this video, made my entire week!

You are my damn hero! My daughters 2011 jeep liberty had this problem. I flushed it, changed the thermostat, checked fuses, and I almost changed the heater core before I saw this..... blend door motor was stuck. Thank you!

DEFINITELY CHECK THIS FIRST! This was the source of the heat issue on my own 2012 liberty and two friends’ liberties, 09 and 11. This seems to be a part that will fail after a few years, so before you go and tear apart the heater core, make sure the actuator works properly first!

Thanks! My daughter's car has the same issue. Apparently, this is indicative of all these Liberty's! As for testing the actuator, I think you can remove it, plug the harness back in, start or turn the key on and move the temp setting to see if it actually rotates. I'll be doing this check tomorrow!

I am having this exact issue, thanks much for the tips, going to run down my problem tomorrow, and this will be a great help!!!

Thank you Josh. I am laid off because of the virus and I really needed this info. You did a good thing for someone who really needed it. :) Cheers brotha

Thank you so much! This is going to save me so much money. I've been unable to swap between air flow directions and the mechanic told me 600 to replace actuator because they had to take dash apart. Lie! I'm doing it myself now!

You’re obviously not a big car guy and can tell you’re not a mechanic but this is the most informative video I’ve seen about this issue. I’ve been trying to figure out why my heat is not as hot as it should be and haven’t seen anyone mention this issue until now. I’m going out to check it right now. Hopefully this is the cause of my problem. Thanks for posting.

THANK YOU JOSHUA KEPP... Your excellent video solved my heating problem. It was a stuck actuator.

Thanks for clearing up the IN from the OUT you explained that really easily & clearly

Greatly appreciate the Info on the Temp Door Actuator, very helpful, Thank You so much... 🤓🥰

I'm not sure if that's my problem yet, but I'm glad I found this video! Great job explaining!

Thanks for the video, i did exactly what you did on you're video, and corrected my issue on my wife's 2011 Liberty. Thanks again. Keep up the good work.

Really appreciate the thorough explanation of the system from the do it yourself’er point of view. Good job.

Excellent, exactly what I needed to know. Thanks SO MUCH for taking the time to post this!

This is by far the best video I've seen regarding the actuators. I can't tell you how long I've been looking for information on this problem. I have the exact same year Liberty as you but my issue is the directional actuator. I've read several forums and couldn't find anything that made sense to me. If there was an academy award for Jeep HVAC actuator troubleshooting, this would win. Vertical video recording be damned.

Thanks. Very helpful. Mine was the regulator, replaced it for $36 dollars at Autozone. Thanks again...

Awesome Thank you! It worked on my 2011 jeep liberty. The grease looked dried so i put a little lubricant and it works great.

This is perfect. God bless you. The dealership was asking for $1500.00 for this fix.

Hey Josh! Thanks for taking the time to make this video.

Great job explaining the heating system. Very helpful thank you.

Awesome man!!keep it up thanks, one of the best videos with good Directions.

Great video, I have a 2008 dodge Nirto, everything looks similar. Thanks for running through all the possibilities it could be.

Kind of excited to try and crack this case! Thanks for the video!

Thank you for the video! Simple and to the point and explained clearly.

What a beautiful demonstration. Thanks

Saved the day, thank you! Was getting ready to head to the dealership til I seen your vid. Mine was the actuator was stuck on cold. High of 32 degrees lately and I thought I was screwed. You the man!

This was great, was exactly what i needed. Thank you!

Thank you for this video. I currently have the blend door problem (the other module you mentioned) I now know the location and plan to replace it. I have no airflow to my floor and when I select the floor heat it turns on the defrost. I'm assuming that it defaults to the windshield when one of the selections do not work

Dang ! Hope this is my issue ! Thanks for posting this lil memo here 👌🏼🤟🏼

awesome info great help thank you sir

That did the trick, Thank you!!

Thanks for the Video!

I had to disassemble mine and it worked great

Ex cellent - just what I was looking for.

Best video I've seen

Hooooly shit listening to this dude was brutal. Good information but my goodness, I wanted to stab myself in the ears...

Priceless!! Thanks.

THANK YOU! 😊😊😊😊😊

You save me from going to the shop to fix it

Great information :) i had the same issue with heat on one side , cooler air on other side. The blend door works as per the gear moving , the switch to adjust heat to other area's too. I did a complete flush , detached the heater hose to the tube on heater core fire wall side. straight clear water in on one side at a time , then did same into heater hose. Refilled with OEM & distilled water , the end result is heat on both sides . Thanks to you Joshua for this valuable money saving lesson .

Dealing with a similar issue with my sister's 2012 Liberty. All actuators are turning. Mechanic thought heater core was plugged. He removed dash only to discover that the heat vent flap inside the heater core was melted shut, not allowing any heat inside vehicle cabin. Actuator turning but gear stripped out? Not sure if that could have been discovered without ripping out the dashboard though. Another situation to be aware of before spending tons of $$ ??

I can't thank you enough for taking the time out to make this video after diagnosing the problem with your own 2012 Liberty. I swapped the "Heat/Cold Door" actuator this morning in my sisters Jeep. Getting the new actuator on was more than a bit fiddly trying to line up both the gear and pins but once it lined up it worked like a champ. I was concerned with reading online about having to visit the dealer for a "calibration" but ours didn't need anything like that. (Got lucky?) That maybe something you have to do with the first gen Liberty's? If your Liberty's heater isn't working and you hear a loud clicking noise coming from under the dash occasionally it's your actuator failing. I paid about $38 for a new actuator at Autozone.

Have a 2012 Liberty as well, heat issues are warm air coming out passenger side but not driver side, and then sometimes no hot air at all. I will use this step by step method to see if I can save myself any money. Thanks

Just lost heat control This has to be the problem fingers crossed 🤞🏼 Thanks for the straight forward video And do hesitate to do more to the Liberty since I have one Subbed ✌🏼

good morning josh, your video is very helpful with my 2011 jeep liberty that is barely pushing out any heat at all. I checked the in and out hoses and both were warm so i moved inside, took a look under the dash and found my acuator. HOWEVER....when i turn my temp dial, the heat door does move, i can see it move under the acuator. Is it possible that it isn't moving the door enough ??? hopefully i hear back soon, it was 18 degrees yesterday here in Pittsburgh, thanks

I have a 2012 Liberty and my blend door isn't setup that way. My lower module actually stripped the gear. I took it apart and removed the gears. My heater temperature still works. (hot / cold). I can't select the mode defrost, floor etc.... I went to the glove box side and turned those gears and was able to change it. Did they redesign them?

I have a 2012 liberty, no heat and now the dash is indicating that the engine is overheating. Had the check engine light turn on couple weeks ago but then it away and thought all was well until I got no.heat. Any idea what it could be? Will still check the actuator though. Thanks.

Fall day. No heat ? fans blowing. Pipes hot. So I took off servo motor and watch it spin when I turned the blender knob. So with my finger I moved that gear the servo hooks into and got vents blowing hot air and then turned blender switch to hot and realigned servo with that gear the servo hooks into. Screwed it all back together and nice Hot air !

Thanks fixed in 15 minutes,,, 2010. Dodge. Nitro

You can find out if the thermostat is stuck open by checking the temperature of the TWO BIG HOSES that go from engine to radiator. After car has had time to warm up, one hose should be HOT , and the other cold. You can temporarily remove fuses to stop the radiator fans from running, and see if the temperature gauge rises to normal temps. Also could cover nose of car with sheet of plastic, or cardboard to block cold air.

When you replaced yours, how did you calibrate the unit?

But thank you for this video Now to flush heater core blowing warmer on passenger side Hopefully that gets me hot on both sides

Hey, what about if you're not getting any air conditioning, and you're getting a reading of cooling fan 2 control malfunction?

The Heater core could still be plugged even if both lines under the hood are reading the same temperature

Outstanding!

This saved my ass! 😭

Hi Joshua Kipp, Thanks for the video. I'm in Australia and we call them Jeep Cherokee here. I have a problem and was wandering whether you can help me. I live in a rural area and the closest garage is a lot way away and I can;t find a service manula online. There is a water sloshing sound behind the dashboard and there is no water running out of the AC drain. Do you know where the AC drain pipe might be so I can unblock it? Many thanks

Thank you

Hi thank you for the info this is really informative...me being a recently divorced single female had no clue or idea what was going on I knew the door blend was stuck based on a couple estimates from people...however being a female I didn't want to get ripped off so I ran across this video because I was looking at something else...l needed to change the air cabin filter and they wanted a whole lot of money to change the filter, air cabin filter and radiator flush over $300...so thank you I just need to find somebody to be able to do it for me. have a good day

I keep getting leaking from my heater core inlet outlet hoses, i hear a spraying noise when i go over 3rpms inside the car. Causes my heater not to work, ive struggled so much with this heating system i just want heat :( i changed the hoses but still no luck

How warm should the heater core hose be?

Easy to try just leave the plug on and change from hot to cold or cold and can you see if it's turned or no

You are my hero ! If we were in jail I would protect you in the showers ! You saved me money and I am forever in your debt ! Thanks man.

Thanks bud

So I have the exact same jeep, when you’re buying new actuators, is it one actuator that you buy twice that’ll go where both of the old ones were? Both my dials are broke

I just flushed my coolant I'm getting heat from the middle 2 vents but my driver side vent blows out cool air. Do you know what would cause this? My blend door does move

What size torx are those on the blend door? Great video btw.

When i turn on my fan it works at all speeds. AC works fine, blowing cold enough for me. Heat works when at the first and second speed setting, but when i turn the fan speed higher it starts to blow cool air. Any suggestions? Would changing the resistor fix this issue or do you think it's an acuator?

Never open the radiator cap when it’s hot

Also. Two more things. I saw you had the part to get to the actuator already off. How do you take it off? Then. When you unplug the negative battery cable for two minutes, do you need to leave it off while you fix the problem with the actuator or can you hook it back up after the two minutes and then work on the actuator?

So if I want to see if it's the actuator thingy under the dash (because I think that's the problem), should I be seeing if the gear moves when I change the temp first thing?

Which actuator would be bad if I am getting no heat on drivers side, but it works on passenger? Drivers side is blowing luke warm maybe even cold air

My actuator seems to be working properly and still at best the air is warm. Now what? Stuck flap?

I don't have air at my feet. It works on defrost instead.

So you should be able to diagnose this by looking at the gears and see if they're turning, before you pull it apart, correct?

Cool have mine a fist fonzy fist smack and the is back for now. Thanks. Ay!

Think this is why my heat works on low but not on high?

Okay my air doesnt work AT ALL. So do you think this would help or is it a waste of time

Actuators are working but still no heat

How can you calibrate it? I wish you would have shown that part.

Why are there so many hanging wires everywhere

Best to do the job yourself instead of taking it to a '' Stealership"".

Those are the Blender Door Motors......

Exactly my problem and it was stuck But how would I check it if the battery was u hooked That was just to cover yur ass I get it

T-15 bit.

Great vid bro! My issue is the other actuator that choose which vent to blow out of...Source Selector(?) Anyway thanks to this vid I know exactly where to start (and save time and money) BTW, you appear to have the exact same stock stereo as I do. If it starts getting sketchy on you, coming on and off; then please check out my vid on how to fix: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DSzEKKNy0jc.html&feature=em-comments Thanks again!

Please turn your phone sideways when taking video.

Um. Um. Um. You could leave that out.

Um...um....
