I have a 1997 F350 Crew Cab, 7.5L engine. My rear power door locks are not working. I recently had to replace the door handle on the driver side and am wondering if I may have messed something up? I was by myself so had to let the door panel hang for a few minutes while I changed the door handle. They did work for several days, but then quit. I was having problems with the left passenger door power lock being sticky prior to this repair. Any ideas?
Also, where can I obtain a good, comprehensive repair manual (bumper to bumper) for my truck? They have them for every year except 1997???
I have over 280,000 mile and want to keep my truck, but it needs some basic repairs, cosmetic and mechanical. I can do some minor jobs myself if I have good instructions.
The door actuators are notorious for going out, but usually not how you described it. When they get worn the will lock, but fail to always unlock. Since the problem started so close to your replacement of the door handle, I would return to that door and check all of the wires going down to the actuator. It is easiest to do with a voltmeter. Find the wires going to the actuator, put a straight pin in each, and use a couple of alligator clips to attach the voltmeter leads to the straight pins. That way you can do it by yourself. Hit the lock button and see if you get +12Volts or -12Volts(if the wires are switched. If you don't the problem could be the wiring coming to the actuator. To test the actuator, if you have a spare battery available, you can put 12Volts directly on the leads to it. If the actuator is good it will either lock or unlock.
Switch the wires (positive and negative) and the lock should go the other way.
Hope this helps. A voltmeter for what you need is very inexpensive if you do not have one and you'll find other uses for it as well.
I have a problem, both by drivers side and passenger side switch will unlock the driver side door lock which has 12 volts going to it when I press th button. But none of the other locks have any voltage going to them. I dont have a wiring diagram to look and see where all these wires go. Does anyone know why none of my other actuators dont get 12 volts?
