In my 96 Century my door locks don't work. The unlock control works but when i hit the lock button it makes a noise like its trying to lock, but wont. It does however lock in the winter every morning when i wake up and its super cold? But as soon as i start my car it stops working... Any suggestions?

 

yeah, i saw this before your link, im kinda boggled on that one.





maybe a bad connection? have you tried cleaning the hraness to the lock actuator?
