Battery draining overnight

[bedrck46]

OK if there was a bigger spark then I would say that something was drawing to many amps Hopefully it was a bad battery and the new one solves the problem

I had this problem for a while. It turned out that the overhead gas computer/map display wasn't turning off when I got out of the truck. I took out fuse #6 under the dash and fixed it. There is a circuit burned up in the compass display that allows everything to work, it just doesn't go dim when it should. It was caused by a small leak from the windshield or sunroof. Sorry for the long winded post. Just thought I'd put my 39 cents in.

Autozone replaced the battery last week and so far its been holding up. With warmer temps and a new battery its been starting as it should. If the battery drain happens again, I will definitely start with fuses and look at the alternator.

Well it turns out the drain on the battery was the rear wiper motor. After not driving it over the weekend, it was completely dead. After a bit of trouble shooting I was able to narrow down the problem to the rear window wiper motor. The motor was seized. After a bit of research on the interwebs, it seems to be a common problem. I disconnected the motor and haven't had a problem since Monday, when I had to jump start it twice.

That would be a good reason to check the amp draw on the battery when the vehicle is turned off There is a normal amount of amp draw but anything over that normal amount would indicate a problem somewhere

Am gonna try this... had my battery tested, was doing the same thing... battery is ok. but I noticed that this started happening, just after my rear wiper motor seized... real frustrating in -20C having to disconnect the battery... Thanks for the read, and sorry to hijack. I'll let y'all know if the same happens with mine.

guitarsmark Try pulling the fuse for the rear wiper motor until you get the motor repaired or replaced
