The temp on the gauge goes up. When stopped at a light. But when I turn on the a/c the temp goes down. Whats the problem? I was told it might be a relay or a fuse but which one is it.I have changed alot but still have problem. HELP!
How hot is it getting in degrees F? Do the cooling fans run without turning ac on? Any applicable trouble codes? Some of the national brand autostores will check codes for free. If you want to check codes, yourself, at the least you need an obd2 code reader.
