Question about 1995 Cadillac DeVille
Awhile back the electric door locks began malfunctioning. Specifically, one cannot lock the doors electrically from inside the vehicle. The doors will unlock electrically. This malfunction occurs no matter which of the four door-locking switches is used. The doors will lock properly when using the remote control device. I have tried reprogramming the lock/unlock features such as light flash on unlock, etc. Have also tried disconnecting & reconnecting the battery. None of these correct the problem.
what it sounds like to me is ,a rod or linkage that attaches from the electrical solenoid 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..

let me assume u have not checked the fuses, meaning in al places the fuses are!, try,under the hood,under the dash and behind the panel behind the rear seat in the trunk, look in your owners manual for these locations and the particular fuse u have trouble with. good luck,hope we helped!

I am having the smae problem starting this week. Key fob has been broken for several months (and on a 2001 Cadillac you HAVE to go to dealer to program a new one.) So I've been using the key-- no problem.
FIrst thing others need to understand. The 2001 Deville has a key entry on the Driver's door ONLY-- not any other door. So you can't just go to anotger door.
Secondly-- I am trying my 'main' key, which admittedly has some wear. But I am also trying my "spare" key which has practically no wear at all-- so this is not an issue of a worn-out key. Both have worked fine in the past.
What happens is that the door lock all of a sudden will not let the key go all the way into the lock. YOu can feel it being stopped for the last 1/8 of an inch or so-- just enough so you can't turn the key in the door lock. Seems like some kind of messed up security feature. But all I know is I cannot get into my car, parked in my garage!

Tips for a great answer:
Command the driver door and passenger door lock actuators to LOCK and UNLOCK with the scan tool, the doors should LOCK and UNLOCK when changing between commanded states.
If a door lock actuator does not perform the LOCK and UNLOCK functions, refer to Door Lock Malfunction
