How do you fix power door locks on 90' f-150 you have power but the door loocks don't work?

Answer 1

usually the acutator motor in the door is bad sometimes they get wet and lock up. You must remove the door panel you can feel down inside the lower rear part of the door and you can feel the motor there is a pop rivit that has to be drilled out from the outside. There is one bolt on a bracket inside the door you can see it. The acutator rod to the latch and power plug must be unhooked. These are not cheap at auto zone they are about a $100 each at Ford you will probably have to finance them.

MAKE SURE IT IS NOT THE SWITCH BEFORE YOU GO TO ALL THE TROUBLE.

Sometimes the linkages are binding and the actuator could not hit home on the power stroke. Make sure by removing door panel and see before you make any costly repairs.
