I have a 2003 T&C when the key is on engine off the A/C blower, cooling fans, windshiel wipers, and power windows all work. But with the engine running none of these work. I am a mechanic and I have never seen this issue. Can someone give me some advice.
With KOEO cooling fans,blower motor,power windows,windshield wipers all work but with
KOER none of these work . HELP
Have you tried just slightly turning the key back or forward when this happens? It sounds like an ignition switch problem.
