Question about 2003 GMC Sierra
I have had 4 occasions now of an intermittent problem on my 2003 gmc sierra hd2500. It is a 6.2 litre automatic trans. if that matters. On these occasions, a combinations of electrical things stop working.
Sometime it is radio only, it lights and changes channer even operates cd. but no sound at all. Once time is was radio and right window stcuck in down position, one time it was radio and doorlocks would not operate. and one time radio, doorlocks and windows did not operate.
I discovered I could fix it by disconnecting the hot battery lead. What is causing this and is it something that GMC should fix? I took it in one time and they told me the radio was shorted.... it' s not. On all 4 occasions removing the hot wire on battery fixes the problem. Occurence frequency of this problem is about once or twice per year.
You might have a problem with the body contro module, have it tested for codes.
