Well, I have the same problem. It's going to the indy on Wed. I had to drive for 2 hours yesterday in 97F heat with NO A/C. However, once the temp. outside gets below 85F I start to get some cool air out of the A/C.

The indy is just about positive it's that sensor in the compressor. He says the wiring can be diverted to leave this sensor out of the mix. This would cost $120 vs. $750 for the complete compressor replacment/recharge/all the other stuff that would have to be done for the full A/C service. I hope he is right.

I too have tried to sell/trade-in my volvo. However, I haven't put it on the private market. I wouldn't wish this trouble on anyone. I also have the piston o-ring problem too that will cost a cool $450.

I would get an indy mechanic to look at it, perhaps they can rewire the thing. My dealer just wanted to replace the complete compressor, but @ 1020 vs. 750 from my indy.

My fiance loves the volvo. I'm ready to be rid of the thing.. I just know the ABS module will fail next.
