I have a 2005 Crew Cab FX4 with a driver side power door lock problem, any suggestions on a fix would be appreciated. Here's the problem....
The power door lock on the front driver side will lock the door locks, but will not unlock them. When using the passenger side controls or the keyless remote, the locks work fine, they lock and unlock perfectly.
I have already tested the driver side toggle switch by swapping the switch with the passenger side, and the problem remains the same, so I know it's not a switch problem.
If the driver toggle switch is hooked up to the passenger side, the switch works perfectly. If the passenger toggle switch is hooked up to the driver side, the unlock will not work once again.
The locks are not binding in any way as when using the passenger side switch or the remote, the locks go up and down very quickly and sound very strong.
