'04 Dodge Durango Limited 5.7 Hemi, 4wd
194,000 miles.

This is a doozy, so be patient.

Problem #1 - last year the 4wd started going in and out on its own - it could be parked in the driveway not running with the keys in the house, or driving down the road, didn't matter. We spent over $500 trying to have someone figure out what was up to no avail. Someone said a transfer case motor ($1000) MIGHT fix it, but I didn't want to spend anymore, and I had read somewhere that was not a fix. We ended up snipping the wire just to be rid of 4wd after (enter problem 2).

I was left stranded with a dead battery. Everything got tested and came back totally fine after that - battery, starter, alternator, etc. Once we snipped the 4wd wire, all was good until yesterday - battery died. Nothing is getting left on, or anything. There are no codes that come up either.

Thoughts?

 

There is a thread about this condition in this section.

Which issue exactly? I naturally searched before hand, but if there is one I missed I would love to read on it - link?

Thanks for the links - Right now I'm trying to figure out the battery issue because we disconnected the 4WD. The truck is intermittently losing power - should I go ahead and replace the battery even though it tests good?

 

There is a highside pressure transducer on the air conditioning that shorts out the 5v reference cause the transfercase motor to shift on its own. To eliminate it just unplug it and see if it still acts up if not replace the transducer. I know you won't have air conditioning while your testing. If it still acts up them it's possible the transfer case motor is at fault.

 

Sorry forgot Durango are awd this was for rams.
