On the power door locks I've seen many times a broken wire in the boot. the boot is the clump of wires at the hindge of the door in a rubber boot and the broken wire is usually in the front doors drivers side but can be in back. The other problem I've seen is someone put the door panel on and restricted the operations of the control rod.
Power locks on Ford E-150 Econoline Vans? If the van was ordered with power locks, they would be installed. Some owners don't want them and they can be ordered without. joedi
you might have the child safety locks activated
It could just be that metal attachment that actually unlocks the door coming loose. If you still hear a noise when you engage the lock/unlock switch, that's probably what it is.
Hmm, a 2002 i would say yes, well atleast it might be an option, but almost every new car from 2000 and up come standard with power locks.
alternator
If you mean while driving, it's a normal safety feature that the power door locks engage when the vehicle exceeds 30 Km/h or 20 Mi/h. If you mean that there seems to be a malfunction causing the door locks to constantly engage when they aren't supposed to, then the likeliest culprit is a faulty switch in one of the doors, or possibly a short in the wiring to the switch. The common places to find wiring problems would be either at the door jamb where the wires get flexed repeatedly, or near the switch.
burnt fuses
It can be your battery, when it doesn't have enough power the computer will not allow you to use power stuff. It can be also one of the relays which are responsible for stuff like power locks, power windows and so on.
Power seats, power windows and power door locks are not fused. They would have a relay and or a circuit breaker. It should be in your owners manual.
you can disonnect the white terminal from the battery clamp but then the windows do not work. the locks often stick on and drain the battery. so i would like manual locks just turn the key. tell what to disconnect
Door locks are protected by circuit breakers. A surge of power to a fuse would cause it to blow. They are located in the fuse panel.
In the power distribution box in your engine compartment of your 1997 Ford Explorer there is a 30 amp maxi-fuse in location # 10 , for your power seat(s) , power windows and power locks . Ford recommends disconnecting the battery before servicing anything in the PD BOX , which would mean that your Explorer would have to relearn its idle , the clock would need to be reset etc.
