My power locks barely work theyre not strong enough to open and shut, whats the problem? connections? power? i dont understand, unlock on the passenger side works sometimes, but other times just makes them flinch....

 

Usually they need the door latch mechanism taken out of the door, the 20 years of road schmutz build-up soaked out of it in an overnight solvent bath, and every moving part lubed with white lithium. Makes them like brand new again.
