today i wanted to use my AC for the first time after winter.......and guess what, i doesn't work. i put my climate control on AUTO and temp. to 65 and there is no indication of working AC. no compressor noise, RPMs don't go up. What can be the problem? i checked relays and fuses and they seem to be fine

 

You need to determime if the compressor clutch is activating or not. When you set controls for ac on is just the outside ring of the ac pulley spinning or is the entire front of the compressor spinning as is normal for an engaged clutch?

 

i dont think clutch is activating. btw i checked wiring and it looks ok.

 

i think u need recharge the system... press on one of the ac valve with tiny screwdrive and see if there is a pressure in the system .. even if its low copressor will not engauge..and ac wont work...

 

this is correct. i had no pressure in the system due to a leak. today i found this leak and i need so called "ac reciever/drier" $90 at local dealer
