'02 VW GTI MKIV A/C issue, PLEASE HELP!!?

I have an '02 VW GTI 1.8T and the A/C isn't working. I've checked the 134a, and the level and pressure are fine, but its just blowing hot air. I've also checked all the fuses which all checked okay...I've not checked the relay switches, but I'm sure the compressor works(bc the fans on the radiator turn on when i hit the "a/c switch" on the dash. My guess is it could be the compressor clutch. My questions is has anyone else had this issue (golf or jetta 99-04)? What number is the compressor clutch relay? Where exactly is the relay box located?(I hear under the batt.) any help would be grateful. and no, I'm not going to take it to a shop bc I dont wanna pay an arm and leg to get it fixed. I dont trust shops as they always over charge. I get the feeling they'd tell me its the entire system and it'll be $1000+ parts and labor...when in reality it was just a $10 relay they replaced in 5 minutes.

Well, there are so many things it could be. On this car, if the ac clutch is bad, the whole compressor needs to be replaced. Unless you have ac gages, you cannot check the level of the refrigerant. It could be a low pressure switch or even the expansion valve.


You must take it to the shop. If you want to be sure that they do not charge you for a big service when they only replace small part. All you have to do is ask to see all the parts they replaced. Also, you can go to several shops and see if they tell you the same thing.
