Question
I HAVE A 1995 CADILAC SEDAN DEVILLE AND I KEEP BLOWING FUSES ON RIGHT TAIL LIGHT AND LICENCES PLATE BUT NOW TODAY IT BURNED THE WIRES UP INTO THE HARNES IN THE TRUNK WHY IS THIS DOING IT NO OTHER FUSES OR BULBS ARE BLOWN
Hello,
You have a short in the circuit and you need to fix it before you have a serious fire.
Once or twice after the fuse blew, did you put a higher amperage fuse in resulting in the burned wiring? I am not saying you did, but many think this is a cure and it can be costly.
A wiring issue like this would not burn out other fuses or bulbs. This problem is in the tail light circuit, but now is exasterbated by the burned wiring which is now a secondary problem.
What you need to do is consider getting another wiring harness from a junk yard first. Chances of repair are not good because you don't know how far the wiring melted together inside the harness.
Once you disconnect the harness from the connector in the body, make sure you have the correct amperage fuse in.
Turn the lights on and see if the fuse doesn't blow. If it doesn't, you know your problem is in the trunk area. Install your replacement harness.
Make sure there was no rubbing or chafing to ground on the old harness. If so rerout your replacement. Before connecting the harness, remove the bulbs from the right tail light and the bulb from the license plate.
Connect harness and see if fuse blows. If not, take a good look at the right tail light sockets for burning or corrosion.
If none seen in the sockets, put one bulb in at a time waiting to see if the fuse pops. If it does, you have a shorted bulb or a socket. If fuse stays good, do the same on the license plate bulb. Check the sockets and the bulbs. You will find the exact problem this way without starting a fire.
Let me know what happens.
The one issue I have not addressed is if you have trailer wiring. Then there is more to do.

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?
