Hello folks!

I have a major problem here! I have a 1988 740 Gle Wagon non-turbo with the AW-70 A.T. I truly adore this vehicle (I have 2 more). But my 2 rear passenger doors in addition to my rear hatch door just simply will not open! The power locks realse but the doors will not open. It seems as though the exterior door handle tends to stick and therefore i cannot get my doors open. How can i access the innner panel if the door cannot be opened? Is there a method to gain access from the door handle itself from the outside of the door? Before the doors failed to open, i use to have to pull up on the door knob on one on e the stuck doors even after the power locks relaesed all locks from the drivers side door. I have tried to spray PB Blaster, liquid wrench you name it into the crevice of the door. Presently the car has 390,000 original miles on it and it runs like a charm! It burns and or leaks no oil, 99% highway miles and strict maintenace, in addition to nothing but premium products! And no rot/rust! So please anyone that has an idea on how to tackle this dabacle please help me. All opinions and experiences are welcomed.

BEST REGARDS!
