Customer Question
My 2007 Avalanche has...

My 2007 Avalanche has a battery drainage that we can't seem to locate. Is this a generic problem with this model? any suggestions?

Mechanic's Assistant: Have you tested the battery with a voltmeter? And can you see if it's leaking or not?

We have determined that there is leakage- after replacing the battery , it is dead within 4 days. The alternator tests good.

Mechanic's Assistant: Are you fixing your Avalanche yourself? What have you tried so far?

I have had a mechanic test the relays, and drain on each fuse. I'm not sure he completed testing before he assumed it was a bad battery.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Nohtig i can think of- I thought it might be the radio or amp fuse, but i pulled those for a couple of days and the battery still died

It's not normal, and the mechanic clearly didn't do these tests correctly. Please see attachment on how to find and fix this issue.

Please understand that I don't know your skill level or tools
you have to assist us. Also understand that I can't see, smell,
hear, or touch the vehicle either, so your patience is
appreciated. JA is a great Q/A site, but it does not replace a
repair shop. So please don’t shoot the messenger if I have to
deliver bad news:)
If you are satisfied with my answer, I would greatly
appreciate a 5 star rating now before you leave the site and I
will still assist you after you have rated me too if another
question pops up. I don’t get credit for helping you until
you rate me

Thanks, Ron

Thanks again and please remember to rate me 5 stars now
and keep this link in case you need me again later on.
I don’t get credit for assisting you until you rate me
My goal is to assist you in the repair of your vehicle by
supplying you with well educated information. I may not
always have the exact fix you wanted to hear, but my job is
to get you on the right track, which I always do. I can’t hear,
see, smell or touch your vehicle from where I’m at, so your
understanding of that is greatly appreciated. There are no
magical answers, but I do my best to guide you in the right
direction.

Ron
