So about 5 mins from home today got the "OVER VOLTAGE PULL OVER" message today on the dash.. warning lights on the dash etc. Just before this happened I notice my ac was not cold. Made it home and left the car sit for about 2 hrs. Went back out and the message is gone. Took the car for a quick driver and everything seems ok, execpt the ac blew cold then nothing but warm air. Now the a/c compressor is new less than six months old and I know the over voltage is probably caused by my voltage regulator on its way out ( I think) I did pick up a voltage regulator. So is the voltage regulator on its way out or just got overloaded and does the ac compressor need to be checked
