QuestionI bought a 1992 dynasty and replaced passenger door and when I hooked up power the security system came on. How do I disable it?
I tried locking nd unlocking the passenger door and that didn't work.
AnswerHi Roy,
Try to lock/unlock the driver door and if that doesn't disarm it:
there are a couple of wires at the plug of the anti-theft module that you pierce through the insulation with straight pins, then touch the pins together once, and then separate them. That replicates lock/unlock of the doors.
To get to the module, located above the glove box:
Remove center support/floor console as necessary. (Floor console removal, if necessary, is described as:open upper storage bin door. Remove two screws attaching front wall of storage bin to mounting bracket. Remove console and drawer. Remove two screws attaching mounting bracket to lower instrument panel. Remove mounting bracket).
Disconnect glove box/ash receiver wiring connectors
Remove the glove box by removing all the 10 screws around the opening and and remove it.
Then look above the glove box opening and there is a crosspiece with possibly several modules on it. Remove the 3 screws on the bracket that attaches it to the instrument panel and lower it down for convenience. If there is a remote keyless module (2 black connectors)remove it so as to have access to two screws that hold the theft module to the bracket. The theft module has a natural color plug with 21 pins. The black/light green wire on pin 11 and the dark green/orange wire on pin 4 are the ones you want to try the pin touch technique to. See if the light goes out.
Then see if it starts. If you get it started and WHILE THE ENGINE IS RUNNING pull the plug out of the module, that will safely kill the system, if you want. Never pull the plug UNLESS the engine is running.
If you want to avoid the problem in the future (rather than pulling the plug for permanent removal) then never use the door key, remote, or the power door locks when you exit the car; rather secure the doors by means of the mechanical push-buttons which thus circumvents ever setting up the alarm system.
I suspect that a wire from the replacement passenger door lock to the module is open or grounded along the pathway between the two. But you can just defeat the system entirely.
