Hi again all. Well, I had a previous post with some issues to solve with my new (to me) Durango. So far I've replaced the radiator to solve an overheating issue, fixed the front end and fixed the engine surge issue (TPS.)

Went to start it today and the battery was dead, it's been sitting for 3 days. Never had an issue before andhe battery is less than 2 years old. Is there a common battery drain issue with these that I could look at?

I'd check to see if any interior lights were left on first. I know my glove box broke and the little light in there drained my battery in a mere two hours. That's my less than technical first approach.

Check your battery terminals and make sure they're clean. A little bit of corrosion could give you those same symptoms. That can of pepsi you're holding can do wonders. HTH

Assuming all is well with the battery and connections, hard to spot lights are the most likely cause, glove compartment, underhood, etc?

I guess I should have clarified a little. Got in, door chime sounds and dome light comes on. Just a little half revolution or so when I tried to crank it.

As far as hidden lights. Don't have a hood light, and actually don't think I have a glove box light either. A place to start tho, thanks. Have heard about PCM s and ecu s messing up and drawing too.

A 2 year old Battery could still be bad. I had a brand new Optima that was bad and another Optima I had only lasted 2 years.

Oh yeah, I forgot about corrosion. Definitely make sure the battery terminals are clean. Your lights can still go on and the door may chime, but the vehicle can still not start if they're corroded.

I chased a dying battery issue on my '99 for a few weeks before I finally found out it was my rear wiper, it had quit working a few months before I had the same issue. One day I go to start the truck and it was weak but started. It slowly got worse until, after it sat overnight, it'd be flat in the morning. I changed the battery thinking that was the issue, same deal.

Unplugged the rear wiper motor and the problem went away.

Of course I've since switched to the 2G wiper setup so it works again.

It's also very common to accidentally roll the interior light switch so that the dome light stays on. Lost count of the customers that would do that and find the battery not able to start them in the morning.
