I have a problem with both door locks. Depress the buttons , lock or unlock and theres a click but nothing happens. Put the truck in gear and both locks lock. I still have to unlock them with the door handles or key. I thought that it might be bad solenoids but why do both doors lock when in gear? Any suggestions?
sounds werid im not expert but does your truck have some kind of aftermarket theft system?
cuz i know alot of cars that when you put them into drive they lock
just throwing that out there
Here is some additional info on doorlocks. Not only do they click but
they move slightly . If the solenoids are bad it seems strange that
they would move the locks when the vehicle is put into gear.
My 2001 f150 has the same issue at times, but before it annoys me to the point of looking for the problem, it starts working again. How lazy we all have become w/power locks and key fobs... Never use the key to unlock the door until the locks started screwing up.
Both door locks work, but only in gear. That says the problem is COMMON to both sides. What is in common? The locks themselves seem to be functional since they work properly when in gear. I'm looking for a control module. Time for Alldata or Mitchell
Same issue. Key will mechanically unlock the doors (Truck has no keyless entry). However from inside the truck, the electrical door switch will only lock the doors, not unlock them. Not sure what keeps the "unlock" part of the switch from working. If I punch the switch real quick the unlock part will work sometimes. I'm looking for a control module also, or I'll check out the actuator next.
