Cadillac Repair/replacing reverse light bulb in a 1996 Cadillac concours


how do I replace the reverse light bulb in a 1996 Cadillac concours

Hi Marvin,

It is difficult giving you specific detailed information to your specific vehicle because although GMs were the most common vehicles I worked on for 3 decades, remember the specifics of one type of vehicle is next to impossible. With that said however I can give you the general answer which should work well for you.
The first thing to do us look in your owner's manual in the glove box. There you will find the exact.bulb number and it may tell you as to how to replace too.
Open trunk.go to side bulb burned out. You will find up to 6 plastic wing nuts you don't need any tools for. Turn them counter click wise until they are all removed. Remove tail light assembly. Note the exact bulb you are looking for. Twist the socket counter clockwise by pushing down. Remove bulb and replace. Reverse for installation. It is pretty simple and should not take you very long to complete the task.

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?
