On my car (86 Deville) the rear drivers side door lock is not locking when i press the lock button on my keyless. Everything else locks up fine, every door but that one. The manual switch seems to be being held back by something, some sort of resistance has built up and the power locks do not have enough power to fully lock the rear door, i can do it manually with my hand but not with the power locks, even from the inside. When i sit by the lock and watch it while i press the lock button, the switch only goes halfway down, leaving the door unlocked, and i have no idea how long its been doing this.... any takers?

what do yea know... it fixed itself..... funny
