It all started with my wife complaining about the radio shutting off for a moment while showing CD error #8, then clicking for a moment then the radio would come back on. Before I could look at it the battery went dead and I took it out and had it load tested and it was O.K. I was told that removing the battery cable would reset the radio and have not seen the error # 8 since. The next week after getting out of the car my friend said I left my lights on, I told him that they go off with the key but upon further inspection I found the tail lights had not gone off. I opened the car and turned off the headlight switch and they went out.(might have caused the dead battery) The last oddity was today after getting into the car and driving away the heater fan came on for a couple seconds then went off then on then off, etc. All this while the vent switch was in the off position.
Are these problems related?? or ?? Any help will be appreciated.
