The anti-lock brake system in some vehicles can malfunction and cause an your motor to lock up.
One reason an electric motor might lock up is if the bearings seize or freeze (not meaning "freeze" from cold weather but "freeze" as in "lock up" and be unable to function).
first what made the motor lock up, and what kind of motor is it , it could be alot of things like no oil, the trans, if its fuel injection and you put gas in the intake to try and start it this would lock it down as well. try pulling the spark plugs and turning over the motor.
Disconnect the battery. Remove the door panel. unbolt the door lock motor, and remove the wiring plug. Replace the motor and put the panel back on.
Yes
it should be on the door lock motor on some early '91 models
This seems to be a common failure. The lock and lock motor assembly need to be replaced. I'm working on the same problem on my 2000 focus right now. I'm trying to get the lock cylinder of from the old lock/motor assembly. Any advice?
It is behind the motor and in front of the transmission.
could be a lot of reasons, i suspect that your boot lock central locking motor has seized, does the motor whirr? if it doesn't then i'd spray some wd40 into it, if it does whirr then the mechanism around the lock may have become disconnected or broken.
The lock has a motor at the edge of your door(in the door jamb) My motor whined but was bad. part was $129.00 for an idea. Greg
broken linkage inside the door, remove internal door panel and inspect all links from lock to motor
Until it restarts.
