Passenger electric door lock not working on '94 sedan de ville
I can hear the electrical movement when i depress the door lock/unlock switch. however, there doesn't seem to be the power to push the lock up or down as the other (3) have.
i can manually (with little effort) move the lock, but the power is lacking to move it electronically.

Re: passenger electric door lock not working on '94...
What it sounds like to me is ,a rod or linkage that attaches from the electricalsolenoid to the lock mechanism has came apart, see these rods and linkage are held by thin metal and sometime plastic clips and they can brake and crack at any given time! u need to remove the door panel and sound barrier and inspect all the mechanism.when u remove the panel lift/pry the window up and dn button panel out of the arm rest and u will see a phlip screw head,this has to be removed before u try to remove the door panel, when the screw is removed,grab the door panel with one hand by the bottom and the top by the window with the other and give it a quick **** straight up, their may be a pop in fastener at the lower left hand corner of the panel, so u may have to pop it out first, then **** it up, u will see plastic fingers around the panel that set in the door to hold it in, be careful not to brake them off, now u can move the panel out of the way enough to do what needs to be done and not have to disconnect any electrical plugs,(hopfully).hope this helps,just take your time and u should have no problem, and save some $. good luck to u..

could be a wiring short, but if you hear the lock motor moving i believe the lock actuator has broken free. the rivets break free at times and i've used screws and washers the reattach the actuator in place without having to pull apart the door. try to see if you hear 1 doorlock at a time. if when you press the button, the motor sounds and theres movement thats your problem. if you press and theres no motor then you either have no power to the motor or its bad. current tester to the switch will tell you either way.
coulb be the control switch on your panel you can take the door panel off and check for loose connections and try to test for continuity. if you dont know how take it to a shop and have them diagnose the electrical. im quite sure it the switch that burnt out
When you use your remote or insert your key in the Drivers Front door all the door locks should work at the same time by the door lock motors electrically. If you have to manually unlock the door because it will not lock or unlock by the lock motor, you need a door lock motor. The drivers and passengers front doors can unlocked with the key manually only. The rear doors you have to pull up the latch. If NONE of doors unlock electrically with the remote or drivers door lock, intermittently or all the time, you will need a Central Locking Electronic Control Module. Pressing the remote button you will hear the "beep", but no door locks will fire at all. If you have a few odd door locks not working intermittently or not at all, you will need a new door lock motor for each door lock that malfunctions. You can hear if the door locks are working electrically. Yes, they are common problem. If you can hear the door lock motor working but the door still doesn't unlock you need to take the door panel off and lubricate the door latch assembly and work the lock, loosening it up. This is common as well. Sometimes a bad door lock motor can blow the central locking fuse. You will notice it because it will take a second or two longer to lock and unlock compared to the others. If the door lock motors seem fine, install a the next step up in amperage fuse. (From 15 AMP to a 20 AMP)
if you hear the solenoid engaging on the drivers door , then it could be catching and not locking or unlocking or even getting weak , if you don't hear anything at all the solenoid may be defective or there is no power getting to it then , but the locks should be on the same fuse , so its not likely a fuse thats blown , are you able to check for power to the solenoid or tell me if you hear the solenoid egaging?
