alright whenver i hit the lock / unlock switch on the drivers side the passenger side door lock makes a grinding sound and wont lock or unlock but when i use the key on the outside the door locks and unlocks but is kind of hard to do. anyone know what could be causing this?
its the actuator startin to lock up it will eventually get to where it wont even lock with the key go ahead and take it out and then it will lock fine with the key.
I had the same problem, but then after awhile the lock basically froze up. It wouldn't open up from the outside or inside--it was just stuck locked. It finally opened up several days later and I'd bet it is the lock actuator. Replace the the actuator.
You can see Jrichker's article on how to swap in aftermarket actuators at a significantly lower cost than an OEM actuator. I did it and it works great.
Stuck with door lock actuators that don't work and don't want to pay the $50+ for a new one? Tried the junkyard ones and found that they last six months and freeze up?
A new actuator for less than $4. Fix one side for $17, do both sides for only $23. I don't sell parts, I don’t make any money off of the upgrade, I just tell you how to do it cheaply and easily.
