I'm having problems completely tuning my truck I have a 2002 silverado 1500 4.8 Os 12212156 When I go to Systems > Fans> It only shows 1st stage & 2nd stage (on and off ect). So I'm basically missing all other options to modify. -Enable speed -Disable speed -On temp ac on -Enable AC press -Disable AC press -Enable delay -Disable delay -Min time -AC Fans Disable speed.
So say you dont want the ac to run the fans what will happen? Does the ac still work just not as cold? can the fans keep up without knowing what the ac is doing? Will the ac work at all?
@@codygentry9472 in my opinion... I think with the fans on at what ever temperature you set, the ac would work just fine. If you think about the clutch fan, it doesn't adjust at all to ac. If it's hot enough that you turn your ac on, it's probably hot enough for the fans to be on. Hope that makes sense
Ok so the blue wire goes to red connector pin 33 so just remove whats there and put in blue ok got that, but what about the recirculation acuator control that is allready there?
@@seabornroberts7512 I don't know the exact circuitry of the recirc feature, but some trucks don't have a wire there and the recirc function still works. I'm wondering if my truck had it now and maybe that's why I never talked about it in the video. I don't remember
I don't this swapped c2-55 to c2-17 then spliced a wire to it and ran it to black wire on switch and spliced it and my compressor wouldn't come on at all did you do this with the bp automotive a/c update kit or did you do it and plug your factory high pressor switch back up?
@CheeHooGarage I think I just seen the problem reading through other comments I spliced to that wire instead of just to the switch itself so it was prolly grounded out I'll fix that and see how it does lol
Well I fixed that and now no compressor or fans on with the switch same as before still and I have straight from that switch to c2-17 and moved c2-55 to c2-17s spot
I had a noise that was similar to the one you have and it was the Bosch Alternator. Funny when I saw that pitted lifter I could have sworn the cam was going to have some damage. I wonder what could have caused that lifter to get pitted like that?
Yea u looking forward to the content. I could be wrong but I seen some videos where that tapping noise could also be a loose spark plug wire on the spark plug. 🤙🏽🤙🏽
Someone hard wired my e fans in and now my ac won’t blow cold. Coincidence? Or will the ac kit fix that? The ac was fixed a week before the e fans, but now it says overcharged, major pressure swings when the compressor kicks on and off. Still blows hot air only though
@@renedeleonjr1858 you can get them from any nbs truck, tahoe, Yukon, suburban that came with e fans. Search "silverado fan harness" on ebay, there's a lot.
Would the fan harness from a 08 Yukon Denali work on a 00 Silverado. I went to the local junkyard and that’s the only truck they have. No Chevy truck 🤦🏽♂️. Thanks 🙏
Thanks for your reply. I didn’t realize the time difference. I’m in Texas One more question Will the fan work from the 08 Yukon Denali. With the fan harness from a gmt-800?
What operating system do you have? What operating system do you need to have for it to work with the hookup like your initial video, without having to do the extra wiring like in this video? I have a 2001 GMC Sierra C3 6.0L
@@CheeHooGarage ok. Explanation for the fixed and variable system lies in the orifice tube. Around 01 they switched to the larger style orifice tube for better refrigerant flow. The bigger fixed orifice tube (17mm) has a fixed flow of refrigerant. While the smaller orifice tube (13mm) is a variable flow, which adjusts the flow of refrigerant to help with cooling at idle speeds. The smaller (13mm) orifice tube also comes in a fixed flow as well. They came out with the smaller (13mm) variable flow orifice tube as an upgrade for the smaller orifice tube system before they just decided to finally switch to the bigger (17mm) orifice tube for better flow to help with low speed cooling. A possible solution would be to find and replace your ac liquid line with one that uses the smaller (13mm) orifice tube and use a variable flow orifice tube. That way it'll work with the analog settings without having to do the extra wiring
I followed your instructions and now my 2002 Avalanche has electric fans! Your video had everything. I followed your directions and got the 7and 9 blade fans and the 2 bolts needed. That a/c up date kit was a life saver. Love my HP tuner. Thank you Sir.
@@CheeHooGarage yes AC was working. Was freezing that’s why I did c55 to c17 and c17 stripped it back and added it to accumulator. Compressor was only cycling for a bit when I turned on the truck but once I was driving it compressor wouldn’t cycle.
I am just finishing up putting 2 inch drop shackles on my 2000 Silverado stepside and I am having to notch like maybe an 1/8" x 3"-4" off of the under bed lip that hangs down and sits on top of the Shackles. Not a big deal for me to do since I thought while doing this project It would be easier to change shackles out with bed completely removed and while its removed I pressure washed the rear of the chassis and cleaned off all the grease, dirt, and gravel that was stuck up in frame rails and it was worth the extra steps to do. Figured it wouldn't hurt to shed off the non needed weight lol. Changing the shackles out with bed removed was a breeze!
Ill wait for your afm/dod delete vid. All the rest i seen arent as thorough as your vids. And half of them are guys just filming them self taking it to a shop!! 😂
@@JDougyJ this is an after market grill so the fitment isn't 💯. I probably could grind down some parts of the chrome piece to make it a little tighter. But the stick out of the black part can't be adjusted. Probably get a better fit with an oem grill.
@0:10 The opening is so clasdic! I lost count of how many times I have been guillotined by my 1999 Toyota Solara and its shot hood-struts failing....followed by the vice grips around the shaft of the stuts coming loose...
Hey bro I’m back to comment hope you can answer my question, so I did everything you explained on the video and I though it was working because I did it on the winter I was having issues with my heater the ac compressor was engaged all the time and was not letting hot air to get into the truck because the accumulator was frozen, so I did what you explained on this video and my heater was working great, now this summer my ac compressor was not engaging so I revert what I did and the compressor started to work again, but now my problem is that the accumulator is not getting frozen it is the evaporator inside the cab that’s it getting frozen and after 30 minutes of driving I’m not getting cold air I guess the frozen evaporator is not letting the air go through, my compressor is engage all the time is not turning off at all is there any reason why this is not working for me? I did everything you explained on the video and is not working! 😢😢 hope you can help me thanks!
You said you did everything I did and it WAS working. Then the compressor wasn't coming on so you "revert" what you did. I would change the pressure switch on the accumulator. Right now it's working because it's not even looking at the pressure switch. That's why it doesn't cycle off
@@CheeHooGarage I replace both, the pressure sensor that came with the BP automotive kit and the low pressure on the accumulator 🤷🏽♂️🤷🏽♂️ my truck is a 99 so maybe there is something weird on my computer, before I did what you did on this video I had the same issue with the accumulator getting frozen, but when I do the wiring you did on this video my compressor is not getting power just ground
@@gerardolopez5875 I just googled it. But try clicking on the link to the forum first so you can understand what is happening. A lot of people message me because they ground the wire instead of looping it in series
i did the efan swap, AC never worked to begin with when i evaced , vacuumed, checked for leaks and filled the system etc etc and THEN installed the bp automotive kit / tune to analog thinking this would fix my issue . troubleshooted, wiring is fine. found out i can only request ac sig manually with VCM scanner and ac works really good. any idea what it could be? im gonna do this method and hopefully this fixes my problem
@@CheeHooGarage im gonna revert back to stock settings ( AC recirc sensor and low pressure - clutch fan ) and see if that fixes my issue. if it doesn't, then its definitely a wiring issue inside the cab that i have to check out. if its running fine like normal then im going to try this method and see if i can get it to work with efans
@@chinogodinezthe problem ended up being the sensor at the back of the compressor. When you get a new compressor, i believe your supposed to install the new high pressure cutoff switch ( Not the recirculating sensor in the front ) before installing the compressor to the engine. But since i already had it mounted and filled up i did not want to evacuate anymore, so what i simply did was cut the wire harness connector to the switch and connected those cut wires with a butt connector. Now the AC works without me having to manually switch the compressor clutch with vcm scanner. Hope this helps out !!
really great video man. really inspired to tackle this myself to do my 02 yukon denali. lucky for me theres a local junkyard that has 07-13 yukons so i can get the fans and also has some 03-06 escalades,tahoes and yukons so i can get the relay harness. lol. what type of laptop did ya use or can i use a tablet for hp tunners and what hp tunner did ya buy?
@@marcotena4158 the hp tuner i bought from Amazon years ago so it's the older version. I run it on one of those cheap hp laptops. Not sure if you can use a tablet
@@CheeHooGarageok. thanks very much for the reply. just wondering if it will be the same process for my 02 yukon denali when it comes to doin the conversion.
Cool to find this video..i have an 00 Tahoe and i had to upgrade my computer to an 0411 PCM..This switch should give you control of the ac fan with ac pressure..the fan shouldnt just come on because the ac is cycling. You should be looking at ac pressures not whether the ac is cycling or not. If you have constant fan on condition you need to upgrade your PCM..I will figure this out so thanks for pointing out it exist..
@@spyderlyf3 my fans operate off pressure and engine temp. I set the parameters with hptuners. The problem was the compressor not cycling off and freezing
@CheeHooGarage yeah cool to see you found the fix. I'm gonna definitely do this wiring upgrade. I don't want turbo fans anymore. Problem is mine is EFI live tuned..gotta start over with HP tuners.. Good stuff either way..
