Question

Answer
Hello,


With more than one problem at a time, chances the trunk motor failed unlikely. I have no wiring schematics fr a car this old.I would be looking at a body ground in the area. I also would suggest you check the owner's manual for all fuse box locations and check them. There should be a fuse box in the dash area and in the trunk on the driver's side.
If you are referring to the pull down motor, in a pinch you can remove the lid edge plastic and you will find three bolts on the latch and you will see the latch is slotted. You can loosen the bolts, push the latch upward and tighten. Try slamming the trunk like any other car. If the trunk does not close, loosen pull the latch down a little more and tighten. Try until the trunk will shut. This way you can drive the car until you fix the problem. Cadillac is the only American car that had this option. I think it is just plain stupid. Those motors fail and cost too much to fix.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
