Cadillac Repair/Dome Lights Staying one 1993 Caddy Fleetwood


I was reading the forum question about a 1993 Cadillac Fleetwood dome lights staying on. You suggested the jam switches could be the issue and how to check them. In my car I don't physically see any door jam switch to turn them on or off. Do you know what controls them in this case or is the jam switch hidden? Thanks, any help is appreciated. Rick

Just wondering if you found the problem.

My memory is foggy on this and please forgive me. I have one answer here and I will give you a general link.
Scroll down and also look at the fixya link.
Do not go to justanswer because hat is a pay site.

The problem is that on many common problems, these problems and fixes are not addressed in the service manual.
It appears as though one of 4 outside door handles has a switch sticking. The first thing I would try would be to open and close each time numerous times to see if that fixes the problem.

This appears to be a common complaint in with one of the door handles controlling the dome light sticks. The problem is that I do not know how to isolate a specific door.
Go to the link, and try sub links to see if there is a way of isolating the problem down to a specific door.
If a four door, the problem most likely will be in the rear doors because they are not used as frequently.
Let me know what you find. Good luck!

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?
