Its been bitter cold in Chicago, below zero at night, barely over zero during the day, the GMC has had trouble starting. First Fiasco was Christmas day, just came in to plow the lot and it would not start. Not plow with this, I have a CJ for that. Anyway, it just drains for some reason. All dome lights are off, heater off, radio off, still drains. Replaced the starter thinking that the draw from the old one was just taking voltage away from the fuel system, but still had the trouble. Changed batteries, just cant find this. Battery shows 14.5 volts when its running, turn it off, it goes to 12.75, within an hour, inside, it dropped to 12.25, so overnight I am sure it dropped to 11 something.
Anyway, just pulling the fuse for the truck body module??? and it seems like the draw stops and was wondering if anyone else had a situation like this so I don't start from scratch. Like I said, its going to be below zero for a while at night and not too keen on pulling the fuse at night and replacing in the morning if someone had this issue and found a cause.
The odd thing this truck does is the turn signal flasher sounds like its on most of the time I am driving, but it may be the 4wd module clicking as well, but that should be off with ignition right?
