MY'02 WRX
My a/c works fine and blows ice cold except under the following conditions:
1. Extended use. After and hour+ it will start to blow hot.
2. Very hot outside(95+ deg.). It will start to blow hot.

In my opinion the compressor kicks on and off way to often in comparison to my previous cars. It switches On/Off less than every 15 sec.There is some grime build up around the compressor but I dont know if it is standard engine bay build up or if its where the compressor is leaking a little oil. Im new to the subaru scene so I dont know if that kind of compressor cycle time is standard fare or not. I took it to the dealer and they wont even give me thier opinion without charging me $85.00. What does everyone else think?
