air conditioner not working

scan for codes then see if there are any dtc's.

AC stopped working abruptly. No AC indicator light when pressing switch, no fan/blower, no compressor
Not fuses

If you're absolutely sure there are no blown fuses anywhere, then it's probably the main control head itself.

Hi Wrenchtech. Thank you for such a quick response. I only saw one fuse that I thought had anything to do with a/c and that was in the engine fuseblock. There was also an a/c compressor relay. Are there other fuses that I should check that would not be marked obviously(to me anyway) that they are related to this problem? What is a climate control head and how is it designated as a part to purchase at an auto parts store?
Thank you,
Dana

You need to test every single fuse using a test light with the key on.

The control head is the unit where the controls are. That will most likely be a dealer only part.

Hello,
My A/C wouldn't work and I was told it was the compressor. We put a new compressor on and a/c still don't work unless we jump it. We checked the fuses under the hood and relays but nothing unless i use a piece of wire where the a/c fuse suppose to be to jump/bypass it that way. How can I fix this issue? I did put a/c oil and freon in it that it allowed me to do but had to bypass it to get it to take it in.
Do you have any other suggestions.

Have you checked the wiring between the switch and the compressor for continunity? Also, have you checked the cycle switch?

My AC was working fine in the morning then when I was heading home in the afternoon it just started blowing hot air. I had the freon levels checked and they are fine. Any ideas?

Thank You

When you turn the a/c on do you hear the clutch engage the compressor,if so-check if the air blend door is stuck on the heat position.

Cooling fans and A/C fan not working. A/C blowing hot air. Have checked the fuses and moved every relay that was possible, still no luck.

see picture of cooling fan relays under hood. if relays are good then it may be fans are bad or ect for one fan or a wiring issue try putting twelve volts to fans to see if they work . it can be those as well then have it scanned for codes by a mechanic.
