Hello everyone. Ill get straight to the point heres my problem

Car:
2k Max GLE with Automatic Temp contril gauge

When i go to turn on my ac it just blows warm air. When i press the AMB button it always says -22 deg which is WAYYYY OFF its almost 100 deg here. The heater works fine though. Anyway the car has lubricant and the R134. the AC lines dont get cold either and when i press the release valve the R134 does come out. The one thing that is not workin is the compressor. the compressor does not event urn on. Does anyone have any kind of diagnosis.

Im trying to stay away from the high priced dealership so any help would be greatly appreciated.

 

oh boy dude.. sorry to say if you hit the A/C button and you don't hear the clutch on the compressor kick in, then the compressor might be the culprit. Check all your fuses and stuff before going to the big stuff. Sadly to say, 95% says its the compressor

 

I hope its not the compressor I already checked the fuses and everything. Oh also it hasnt been workin since i got in an accudent and they hit the front passenger side of my car could an impact cause the compressor not to work? it suc my gf dont even wanna go in my car lol

 

I agree, it's probably the compressor. Def. check all the fuses first. Sometimes it's something as simple as that. Stay cool.:-)

 

its not a fuse i check all of them already

 

there is something unplugged. That same thing happened to me and I brought it back and they forgot to plug something back for the ac.

 

thats what i was thinking since the AMB button doesnt work. Do you know what it was?

 

It's possible that the accident caused the refrigerant to leak out. If this is the case, the system shuts off so as to not damage the compressor. It does this because the refrigerant also lubricates the compressor. No refrigerant = no lube = death to the comp.

Worth a try to get the system leak checked and if there are no leaks, evacuated and refilled.

 

well last nite i had a friend who used to work for a dealership check it out and there was refrigerant and lube in it so i dont think its a leak. We put a screwdriver to the AC hose release and the green lubricant came out so he said theres no leak. any other suggesitons? I still have a feeling they didnt plug something in when i had it fixed.

What would cause the AMB to say -22?

 

take it back and have them recheck it. also mabe unplug the batterie

 

Check the relays under the hood. Unless you have already

 

Already check the relays. Id take it back but i dont want my car sitting there for another 2 months.

NOTE: I just got under my car and noticed theres a plug thats not plugged in to anything i think it plugs in to the Window washer fluid box? i dont know though and theres also 2 wires just hanging i dont know where they go. they dont have a plug ont hem just a metal tip on both

 

You can get a compressor cheap on ebay.

you might have a corroded connection some where along the line, If your rad busted during the crash.

 

What accident are we talking about here? The dog with a sweater, or something else?

 

No it wasnt the dog lol that one just cracked my bumper. The radiator didnt bust either she just clipped my front end.

 

An easy way to check the compressor is to run a hot wire to it and if it doesnt turn on the clutch is bad or the complete compressor is. I had the same problem and it was a relay.

 

Thanks but i have no idea how to run a hot wire to it lol

 

no to be silly... but at first I didnt know how to run the A/C.... then I realized it would only run if I turn the AUTO and not only turning the FAN and dropping the temperature...


If you knew how to turn on the A/C (and it has worked in the past) just ignore this post. It is more for newbies (like myself) that didnt know the A/C would only run on AUTO mode.

Later

Yea i know what you mean but it has worked in the past worked right before the accident I just dont know whats wrong with it

 

Isn't 22 the main error code for the auto a/c system?
Check around here for the way to put the auto a/c system into diagnostics mode, it will flash trouble codes.

 

really? Kool ill try this let me see if i can find anything if you find it first let me know

 

How did that go ... did you PM the Dr? You should've ... If not just ride around in diagnostic mode and chill out ...

 

Yea i sent him a PM he hasnt got back to be yet im going to call and see how much that sensor is though. Good idea about the diagnostic mode lol its too had to have the windows down lol Thanks for your help last nite

 

After my car accident, my ambient temperature read -22 degrees. I also realized that at the same time, my coolant leaked out, therefore, the compressor wasn't engaging. I told the shop to order another ambient sensor (since I thought it was damaged because the display read "-22" and it was actually 50 degrees). Of course they put coolant back into the system and the A/C works fine. Now, I'm positive that the A/C works because they re-filled the coolant, but I don't know if the "-22" was a result of no coolant in the system, or a bad ambient sensor.

 

Hey man thanks I found out it is the ambient sensor and i ordered a new one. DR. Roy from here helped me when i did a search i found his post on how to do a self diagnostic and everything worked on it cept i got a bad sensor code and all the other sensors on my car were reading right except for the ambient. I ordered one online for 23 bux we'll see when it gets here

 

manual temp control > than that flashy ish.

 

But does the manual temp control have that cool hidden function

 

...............

 

take it back so they can fix it properly. call your insurance company and complain about
