Battery I cant get the backseat off to inspect battery

It's under the hood. Fuse #32.

Rear window seal leaking or inspection plug missing under the carpet

Could be a switch under or around the trimming of the seat. if you cant figure it out take it to the dealer they will be happy to help you.

The driver's door should open with the key. Then you'll have to access the trunk through the backseat.

There is an emergency trunk release located inside the trunk. To gain access, there is a pass-through in the rear seat. Put the rear armrest down, open the pass-through, and move the release up with your fingers. The release is glow-in-the-dark. So you should have no trouble finding it using a flashlight.

The seat release straps should be on the top of the seat backs on the edge by the C-pillars.

The same happened to my durango. Just get a can of wd 40 and squirt it inside the lock and anywhere you can and jiggle it around a little bit. It should open up. Let me know how it goes! Good luck!

When I hear situation like this I do it for free,You cant go through the backseat,The fuel tank has to be dropped,Its better to pump the fuel out of the tank From there you need to remove the fuel lines,then you need to remove the fuel inlet hose,Once you have the fuel tank down then you will need to remove the fuel pump flange,one removed you now have access to the fuel pump

before my mom died she had an upholstery shop and she made several tops for jeeps and trucks...find a good upholstry shop and they should be able to fabricate a topper

Backseat headrest is realising by shifting theare horisontal position and pull up in vertical direction. It is only ficsation of the upper position and remuving whith backseat toghether.

You say you can't get into the car so you cant go through the backseat. Call a locksmith to open your trunk. Don't damage anything you will be sorry later. Should cost about $40.00. Or you can pop the lock out of the trunk. Call a locksmith.
