Have a battery drain problem

Have a battery drain problem

Postby jumpervb [OP] » Mar 21 2011, 1:11am

Just found this site and I have a question. My 2003 Silverado has developed a drain on the battery. I really have no idea why other that a couple weeks ago I had to replace the passenger side mirror which is power with the turn signal but not heated.
Could the new mirror be the culprit?
It's not blowing fuses but it is draining the battery. Any Ideas?
It kills the battery in in 24-36 hours depends on how well charged it is.
It also has power seats and heated seats.

How is all the wiring going to and from the battery? Have you checked your battery ground to teh chasis?

Have you checked your alternator?

Did the new mirror have a ground to it? If you installed it youself you may want to double check everything, although it seems odd that would be a problem.

Did you do any wiring yourself, or did the replacement have the plugs for the master switch?

Had the alternator checked at Advance Auto and they said all was good. :roll:
The mirror was installed by a friend and he said it was just a plug connection. He is going to take it loose today so I can see what happens after that. That is the only thing that has changed with the truck.Can someone tell me what fuse controls the mirrors? And which fuse block it's in? I have found 2 but did not see any fuse for the mirrors.
I know it has quite a draw on the battery from just taking the positive cable loose from the battery and touching it back to the post. I would expect some draw but not what I'm seeing.
Have not checked the chassis ground yet.

Have you added any aftermarket stereo equipment or accessory lighting?

No, replaced the battery with a new one last week and it went dead in less than 3 days.

Best troubleshooting you can do is remove any recently installed equipment, if you still have the original, have it put back on and see if the problem still exists. That will at least narrow your search and rule out the mirror as the problem.

The reason it was replaced is because it got broken when I hit it agaist a concrete pillar. Didn't tear it off just broke the mirror and messed up the housing just a bit.
So I dont have it to put back on.
