So I have a 2004 h2 hummer and the front passenger interior door panel is completely falling apart. I have been looking around and a local salvage yard has an interior door panel for sale but it is from the rear passenger door. My question is would the door panel from the rear passenger door work on the front passenger door?

 

My question is do you own a tape measure?

 

They're not even close to the same door panel.......

 

it definitely won't work...your best bet will be to get the door panel off eBay but they're pricey. Unless you're lucky enough to have an H2 at your local junkyard. Have you tried taking the door panel off and inspecting it from the other side ? Some of mine had stress cracks in them and I fixed them from the inside using beige epoxy. Can you elaborate on "falling apart"?
