I just pulled a 77 Cap out of some bushes and she’s in beautiful condition considering that she’s been in a briar patch for 22 years but for some reason the driver side back door is the only one I can open. Anybody know how I can get these other 3 doors open?

 

Assuming they are not locked, I'd pull handle, and kick it open with my feet. Latch is probably rusted.

 

Doors are unlocked I also noticed that the locks won’t even go down🤔
