No, the bumper kit solves the above-described problem with the power locks not working correctly. If your lock is stuck in a certain position it is probably a different internal problem.

Dunno if this will help but heres a little input from my previous expiriences. This past summer I noticed that my power locks would cease to operate if the exterior door handle was slighty lifted when trying to unlock the door using the keyless entry remote. Initially i had thought that the lock mechanism was broken but I refused to stop fooling around with it to try and get it working. Following this, I foulnd out that if you physically hold the lock indicator (plastic thing with the orange sticker under the interior door handle) in the open position while repeatedly flipping the lock switch on and off, the lock will start working again. I can only assume that when it stopped working that some internal latch must have come lose, and that holding the lock caused it to go back to where it should be.

Yes. It needs some lubricant on the latch mechanism inside the end of the door. Not the easiest thing in the world to reach, but that'* what you need to do.

yeah my problem is with the actual lock. i can use the power locks fine in the summer on both doors no problem, but as soon as the cold weather kicks in my lock will basically freeze. i would hit the keyless entry 2 times to unlock all doors and the passenger door would stick. ill even try to unlock the door with my key and it wont work. i am going to try the bumper kit.

Um, I'm not sure the bumper kit is the problem here. All the mechanisms (key in the lock, or the manual plastic slide on the inside door handle, or the power lock solenoids) all converge on the latch mechanism inside the end of the door where the striker hits. That mechanism is apparently so dry that the lock/unlock pieces are not slidely smoothly, but getting hung up. You need to get some lubricant right in there on the latch, and in fact from what I remember of fighting with a Buick Regal door, the lock portion is at the _bottom_ of the latch.

If you're going to open up the door anyway, great; put a bumper kit in if you have one, but be sure to lube the latch thoroughly while you have access, and don't put the door panels back on until you know it'* working again.
