1999 buick park ave

[danp76]

I can't open the rear doors on this 1999 Buick Park Avenue from the inside or the outside...any ideas?..doors were working at one point and now they are not. No autobody damage to either door, but won't open from inside or outside...ideas?..not sure I can get door panel off with door closed...

GM's are easy... OK I was a repo man and a tow truck driver... but, when we would slim open a GM 99% of the time the door never unlocked but did open. the trick is to hit the latch at the door pin and push down to open the door. A strong piece of welding rod or even an old car antenna without the ball on it should work great. The trick is to hit it just right. Like threading a needle. If you cant get it after trying a few times hit the local junk yard and pop a door panel off and play with it. That is what we would do to learn to slim a door open in 5 seconds or less.
