Answers :

Try cleaning the throttle body and air idle control valve (IAC). The computer kicks the idle up when the a/c is on, if your throttle body or AIC valve is full of crud it will idle very low and feel rough.

I have a 1999 volvo s70 non-turbo 2.4 5 cyl. I bought it 1 year ago with 124k. It runs great, but the a/c cuts off when it gets over 90 degrees. At freeway speeds, it stays on (until it gets around 100 degrees). If I turn off the a/c and wait 3 to 6 minutes, it usually starts blowing cold again. When it's working, it blows cold. Any help would be greatly appreciated.


There have been a lot of problems with the compressor cutting out when it gets hot. When the A/C begins to blow warm, check the power supply wire to the compressor. If there is power in the wire, you will most likely have to replace the compressor. I ... 1999 Volvo S70

2002 VOLVO S80 2.9 (non-turbo) the plugs for non-turbo lines are leaking oil and have to be replaced. The mechanic says it's about 5-6 hours of labor. While the car was up on the lift I could see where these lines are and how the plug is missing. It appears to me that these plugs can be jimmied in somehow. Is that the case or does the mechanic really need that much time to plug the lines. In addition the mechanic said I would have to replace the breather valve, another two hours of labor. Is th
