I have a 99 F150 that had the same power lock actuator problem that has been posted here so many times.So I tore into the actuators and replaced the weak shunt in the actuator motor with modified penny.The actuators worked great!My problem is now when i use my key fob the locks work backwards.When i hit lock once my drivers door tries to unlock,when i hit it the second time the passenger door unlocks and the horn sounds.Idid the actuators one at a time so no mix-up on sides,and the plugs will only connect one way.. Any ideas on this one would be appreciated!!!
