96 F350 CC (4 door) Power locks won't unlock. Changed both switches. pass side will lock but neither will unlock. Disconnected all 4 actuators 1 at a time, still no go.
Getting frustrated. 14V at all plugs at actuators. was getting 3-4v on lock side or unlock side and 14 on other, till I disconnected front pass side actuator, now 14V & 0V (must have bad actuator on that one) could they all be bad???
Both rear doors are now connected and they lock no problem, still wont unlock.
Both switches give 14V when pressed to lock or unlock.
Cant really help you other than say i have chased a similar problem with mine. I have the RKE system that doesnt work right and my door lock buttons dont work either. I replaced both switches and it just clicks under the dash. I checked all the actuators and they all work. I concluded a ground to short somewhere or the RKE unit was bad. I even used the trouble shooter on the factory cd.
