Why does my car run hot when AC is on?
Engine overheating with AC on is generally caused by one of two possibilities. One, is increased engine load caused by a failing AC compressor. Plugged or blocked radiator condenser fins, fans not working efficiently or a water pump that is not circulating coolant could all cause overheating with AC on only.
Can AC compressor cause overheating?
Yes. A car AC compressor can cause overheating of the car engine. If your car AC compressor has been seized up, the belt will not be able to move properly. A bad compressor can cause a car to overheat, and also, you should ensure that the water pump is working effectively.
Does car run hotter with AC on?
Automotive air conditioning (AC) will cause the engine to run hotter in the summer because it creates more heat in the engine compartment and there will be more strain on the engine to operate the AC compressor. Every time it cycles on it creates more strain on the engine and in turn will create heat.

We’ve had our XC90 ONLY two weeks and @ highway speeds (70-80 mph) our Air Conditioning is intermittent. But in town, it was fine. Anyone else had/has this problem. Memorial day weekend was in the 90s, and we were really PO’d.
What to do when your a / C is not working in your Volvo?

A/C starts off cold then blows warm. The a/c starts off cold and within 5-10 minutes the air is coming out luke warm. I shut it off for 5 minutes and turn it on again and it blows cold for a few minutes. It will blow cool when the weather is cool. When the temp outside is above 70 the above cycle continues.
