AC problem

Hello everyone,

My ac isn't working. It stopped the other day, but I turned the car off and back on and it worked fine. Yesterday it stopped and would not restart. I got someone else to start the ac for we while I watched the clutch, but it doesn't seem to be trying to engage. Does anyone know if there is a relay responsible for activating the ac clutch? It could be a fuse, but since it started up again before, I don't think thats the cause. Thanks in advance!

I did check for codes but there were none. I found the relay and it is engaging so now I am trying to find the connector to the compressor to check it. Do you know how to access it?

On my compressor looking directly at the compressor from the inspection cover in the wheel well, the connector faces the front, you can see the BLUE plug disconnected in this photo, Mike

What can happen sometimes.....

The AC clutch is a wear item. After a while, the air gap can get too large for the coil to pull the clutch in.

Typically you will see this when.....the car is cold....AC works....but...as the compressor/engine warms up and expands just slightly....just enough for the clutch to quit working.

I think you can move the clutch in or out to adjust the air gap to the spec. in the shop manual. The removal/installer tools are required.

Thanks guys, I found that connector and it is faulty. By moving it around, you can get the compressor to engage. I guess that will be my choir for tomorrow.

thanks again.
