My '98 V70 T5 has great cold A/C... but if you run it more than say 5-10 minutes or so, the thing kicks off. It's as if there's some sort of electrical relay or sensor or something that is getting hot. If I leave the A/C on, it may kick on again, it may not. But... if I reach up and turn it off for 2-3 minutes and then turn it back on again, it'll immediately kick back on and freeze ya out.

Any clue what's going on here? AFAIK, it has nothing to do with coolant; it doesn't quick cycle or only partially cool. When it's on, you could just about make ice with the thing. I've searched the forum and didn't find anything immediately descriptive of this problem. Any ideas would be greatly appreciated... thanks in advance!

 

Wonder if your compressor needs reshiming!.
