My Tahoe starts to overheat when idling with the a/c on, but its fine when the a/c is off or while driving. When idling with a/c on and it starts to overheat I can rev the engine to 1000 rpm or more and it will cool back down. I have replaced the thermostat and coolant but still no luck. HELP!
have the same problem?
