Cadillac Repair: DOOR COURTESY LIGHTS TROOBLESHOOTING, auto theft SIU expert, auto theft expert


Question
QUESTION: HI, My 94 Cadillac Fleetwood has a interior light problem. Always the lights are ON. There was not possibility to OFF it, We check the micros in the locks and they are OK. The dimmer works properlly in all functions but can´t off the lights.

Can you help me? Thanks in advance for your help.

And...it´s possible to cancel the speed beep beep???

ANSWER: Hello,

You say you checked Microsoft in door lock. What does that mean?
It's been a long time since I worked on one of these. Does it have a switch in the door jamb near the end of the door on the pillar? Those switches would fail and cause the dome/courtesy lights not to go out.
If that is not your problem, you are going to have to do things the old fashioned way. Remove a bulb, see if the lights go out. If not reinstall and go to next. You may have a shorted light assembly.
See if you have a plunger type switch at the door jamb. Depress all the way with your fingers. You can remove and disconnect. If lights go out, you know you need to replace t g at switch.
Something is telling the car the door (could be any) is not closed.

QUESTION: First of all..thank you for your quick answer. The 1994 Fleetwood don´t use the old fashioned door jamb switches, this car was equiped with some "micro" chips in the door locks who check if it´s door open or closed, so sophisticaded...and seems a litle problematic too.

We check at old fashioned way that these micros give the right information to the CCM and they do it...but light still are ON always...

Any other possible answer to the "mistery lights"?? Thanks

Answer
Hi,

I am sorry I could not get back with you sooner, but we bought a new house, moving and all that fun stuff lol

I am still in the same shape in which I yet do not have internet service for my computer and I cannot copy links on this Android like I could with my iPhone.
One of the pages I looked up by using this to search was "1994 cadillac fleetwood dome lights dont go out."
This appears to be a common problem with like kind GM vehicles.
Like you, I have had to answer questions from across the world, sometimes forgetting that dealerships are not as easy to access like we have in the US.
Try different variations of the question I posed to the internet.
At this moment, I do not know when I will get an internet connection for my computer, but check back with me in a couple weeks if you haven't fixed the problem and hopefully I can send you some exact links. Hopefully if you soupy that question to the internet, you Wil find the appropriate repair for the car.

MERRY Christmas from Texas!
