Chevy Malibu Blower Motor Resistor Replacement (2008-2012) 

No sorry just this video and one on changing the blower motor itself

Originally, the blower motor didn't work at all. Replaced the blower motor (which I also have a video on), and then the blower motor worked, but wouldn't turn off lol. Replaced resistor and that cured the on/off issue. They tend to fail together.

That would be my guess without doing any actual diagnostics.

Yeah, I don’t think it grounds or anything via the mounting screws.

@@TonyTheTruckGuy i was impatienct and just plugged the fan without fulling installing it. it turned on and thats how i knew it was the fan lol

@@0livareZ I do stuff like that too that way you don’t waste time finishing the install if it’s not going to fix the issue 😂

Just looking up a wiring diagram quick here and yeah it shoes that the HVAC controller you say not lighting up should have a 10A HVAC BATTERY circuit control fuse which is SAYS is a red wire with white stripe going to pin #8 on the X2 connector at the HVAC controller and that should have ~12V all the time. It also lists an HVAC control IGNITION fuse which is also a 10A which SAYS it's a brown wire going to pin #7 on the X2 connector which should have ~12V with the ignition on. There's also a "run relay" that should be labelled in one of the fuse boxes, you may want to swap that with a sister relay. Check that and let me know what you find and we can go from there!

@@TonyTheTruckGuy I’ve been reading into and seen a video. There is power at both fuses and the power wire (the red and black wire). The relays and fuses are good. In the video he says since its getting power flow from both ends and its still not working, the fault is with the BCM and that it should be swapped out. I’ll do further testing to make sure. And thank you so much. No forum was helping me.

@@TonyTheTruckGuy okay i just went to buy a power probe. Im getting 0.1 with HVAC CTRL (10A) and HVAC BLOWER (20A) with car ignition on.

@@dalrishardin9993 How about with the car running? Also which engine do you have? Just trying to look up the most accurate wiring.

I have a blower motor replacement video on this car as well I'll post down below. You'll see the blower motor connector with 2 pins in it at the 1:25 mark. Get a cheap multimeter from the hardware or parts store if you don't already have one and set it to volts. Turn the car ignition on and turn the blower knob on high. Then touch 1 of the leads from the multimeter to 1 of the pins at the blower motor connector, and the other lead on the multimeter to the other pin of the blower motor connector. If you're getting about 12 volts or more, the motor itself is likely bad. If you're not getting good voltage, flip the blower knob to a different speed and check the voltage again. If you still don't have good voltage, it could be the resistor, the switch, or wiring. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EXcLp-Zmdik.html

Tony The Truck Guy thank you

No problem, Let me know if you need any other help.

Never a bad idea to disconnect the battery when doing anything electrical, but as long as you’re not jamming random metal objects into the power pin for the resistor then you should be good 🤣 I’d just make sure the ignition is off

It takes 2 seconds disconnect the negative terminal anytime you're working on something electrical in the car

Ok

Probably the fan speed switch at that point if I had to guess without doing any physical diagnostics. I’m not sure if you can replace just the switch or if you gotta buy the whole climate control assembly

i should add that her car doesnt have the climate control...it just has the dial that you put to the left for cold and all the way to the right for max heat. It doesnt have a digital readout

@@Snakebyte70 Sounds like either the resistor or the blower motor switch

@@TonyTheTruckGuywell I’m hoping it’s just the super cold weather 😅. I’m guessing the Malibu’s without the climate control would also have the resistor since the fan speed level switch/dial are the same. I’m hoping the resister is as easy to change in hers as it is in your video though. Thanks for the reply 👍

@@Snakebyte70 Yeah you should have a resistor still, it may just be a different part number.

If you mean the cabin air filter, it’ll be behind the passenger glove box if you have one. Not all cars have one, though.

Could be several things but the most likely causes would be either the mode switch itself (the switch that changes where air comes out of the dash), a failed blend door actuator, or a broken/stuck blend door.

I had the same exact thing happen to my 2010 Malibu. I ended up having to replace the whole AC Control panel which was very unfortunate.

Could be either, you’d have to do some actual testing without just throwing parts at it. I have another video changing the motor itself on this same car. They seem to go hand in hand pretty commonly.

Oh yeah it started working when I replace the blower one week later I'm having resistor connection problems I shake it it turns on from the resistor but now it does not turn on at all when I shake it

@@bobbyowens1926 Probably bad resistor or just a bad connection. The connector may be melter or corroded so that would need to be fixed if the resistor is not the issue.

What do you mean “cut the fan on”? You mean it’s stuck on full blast?

@@TonyTheTruckGuy Yes sir I cut it on the first button and its full blast I think something is not hook up right, they did order another part in case this is bad. they order the blower with the resiptor when the only thing I needed was the resiptor the blower was fine. I hate to go to the dealer because they will have to take it out and put back which they will charge a arm and leg. Thanks for replying back and I will let you know how it goes hopefully they will see the mistake .

@@Change2be1 Sounds to me like the resistor is bad, maybe it’s the wrong one.

@@TonyTheTruckGuy I hope that is all it is they did order another , When I turn it on the 1st knox its full blast in fan mood as I turn the button still fan mood. I am glad I do have the air with this hot heat but its on full blast . thanks for your reply.

@@TonyTheTruckGuy I did call them again to see if they would maybe order another part but he pretend he forgot to order so it was a on and on story. It has been a month now so I decided to go somewhere else and when I told them what I paid for the part they couldn't believe that cheap. And also they did check it and found out its the wrong resipitor and the wiring was wrong too. So I will be going back to this place and they have to order the right part which is a little more money , but at least it will be right. I had dealt with the other company for awhile for minor fixing now and then but have known them for years. The son put the part in and I feel instead of going to the father to correct behind him ( which he do and didn't) he wanted him to believe it was right but it wasn't. The other place I am going said I needed to go back and they should repair it for free but like I told him I don't want them to touch it now and I feel sad but I'm not mad and I didn't tell the other place the name of the company because I don't feel that would be right, I believe in doing the right thing and know that in the end that the next person they deal with won't be as kind as I have been, you live and you learn.

You mean just the blower isn't working again, or nothing on the climate control display even lights up/functions?

@@TonyTheTruckGuy sorry I meant to say the blower motor is brand new but now my climate control aren’t working like there’s no lights coming on or anything I checked the fuses but they all seem fine. Would you think the resistor is bad ? I also heard some clicking sound coming from behind the climate control panel before it went dead ?

@@bluedevilg3542 The resistor should only control the blower motor, so if the climate control isn't working at all, I'd suspect something else. If all fuses are for sure good, make sure there's not a second fuse box somewhere, and make sure to check if there's any relays for the HVAC. Might be worth swapping with another relay if you find one labelled HVAC. Other than that, it would have to be the HVAC controller itself, or some sort of other module/wiring.

@@TonyTheTruckGuy thanks for the info

Blower motor shouldn’t have anything to do with the check engine light so you probably have a different issue going on. Need to scan the car and see what codes are in there with an OBD2 tool.

@@TonyTheTruckGuy did that and it's the ac/heater resistor. It's under the glove box. Ty anyway I'll figure it out. Just want to reset and if the light comes back on I'll take it to a Chevy dealership.

@@irvinaboydjr6700 Oh weird I never got an engine light on this one haha. Yeah hopefully clearing it out does the trick.

@@TonyTheTruckGuy this car is not in good design u have to take the front nose off to change a headlight. Now I've been told take off the hot from the battery for 2 minutes then put it back on and drive it for awhile. So I'll take a night time cruise lol

@@irvinaboydjr6700 Yeah it's a shame how difficult they have made it just to change a headlight bulb on modern vehicles. The disconnecting the battery trick may work for the engine light. Fingers crossed!

@@jeffrytessier-uq1dc Yeah the early 2000’s Dodge Caravans had similar issues where they would chronically burn up blowers, resistors, and switches.

My resistor was $150. I was saying that it would be about $300 if you had to do the resistor AND the blower motor, as the blower motor I replaced the week before was also $150.

@@TonyTheTruckGuy oh thank man

@@TonyTheTruckGuy one more question. the link of the resistro you gived is unavailable, can a resister for a 2011 malibu can fit in a 2012?

@@failsans4079 I can’t say for sure but I’m guessing so. Remember to check if you have the auto climate or not and order accordingly.

I have auto climate control what parts do i need im trying to order parts online and wanna make sure i get the right ones im getting the blower motor and resistor plus front complete loaded struts

HAH! Nah, I didn't pay for it, so it's all good haha. Do you have a link so I can update the video description? The one I have linked isn't available anymore.
