Question about 2004 GMC Envoy
I recently tried to start my SLT and thought the battery was dead. Lights, radio ect all work fine however the clock on the radio always goes back to 12:00. Car will strat now "most of the time". There is a clicking noise so it might be altenator or starter not sure. When I remove the key it will continue to make a clicking/grinding noise then turn off.
It sounds like you need a regulator for your alternater it is reversing polarity there for draining your battery and reseting the clock. it is located on the back of your alternator.hope this could help.
