My car has power locks but the driver's side doesn't work. You can lock it by hand or with the key just not with the button or keyless entry. What would cause this?

 

X2 indeed!

I got the same issue, I opened my door up & was confused on what wires to check on the lock itself with my testing light. The Haynes book didn't help too much either, it told me to test terminals that weren't even there in the door lock connectors.

 

I figured it has to be some little plastic piece or something. Anybody have this problem and fix it?

 

you can lock it by by hand and key cuz your power door is not hooked up...check the switch and the wires..get the maintenance book for your car to get real information.. you really cant get that much here without a picture.

 

Well I can push the button on the drivers door and it locks the passenger door and I can hear the driver door trying but it just doesn't lock. Where is the relay? Does each door have it's own relay?
