I'm about to sell my Tib. I need to replace the door locks on both sides, as well as all of the other things I was blessed with replacing and fixing. How hard is it to fix or replace the door locks? My passenger side door won't open unless the key is in the lock and turned. This car has been the bane of my existance.

If its the door lock actuator its very easy. ..I had to replace my passanger side and followed the diy on here and it was a breeze....i got the lock actuator from ebay...on my tib when i pressed lock sometimes the passanger side would lock and once i would press unlock it would move a tad but not enough to open the passanger side it was slowly dieing so i had to open the passanger side manually thats when i knew it was the door lock actuator
