2000 escalade windows and radio stopped working at same time,,..

there is a fuse at the rear of the radio so remove the radio and check that one first

Do all these things quit working at the same time? If so, I would be looking at my main power circuits - like possibly a bad ignition switch.

On this website you find fuse box diagram and description for Cadillac Escalade mk1 (1998 - 2000)

It sounds like you may have blown a fuse the tail lights and dash lights are usually on the same fuse. Do you have the owners manual? That will show you where the fuse boxes are located and which fuse does what. If you find a blown fuse and it blows another one right away, there's a problem in the wiring. You'll have to get it checked bt a mechanic.

i would check the switch that turns on those lights
hope this helps

as far as the windows it could be the window regulators or the motor in the window switch

Not positive it is the same thing, however, when setting up my iPOD adapter to the radio, I made the mistake of not following the instructions to the T, and it caused my sunroof to stop working... after a day (which I later found out gave the system enough time to "reset" and connect), I turned on my stereo, pushed the 3CH to Dolby Surround, and that did the trick. It's been about a year... and I've had no problems with the sunroof!

make sure the back window is all the way up then try the wiper, if it still does not work then it is a sensor for the rear window (about $30.00) if you installed it yourself

I had the same problem... Its the bcm or body control module. Its located in your center counsole. At first I was able to fix mine by using a giant zip tie and securing the electrical connection into the bcm unit because it was just making a bad connection. That worked for about six months untill in completely stopped working and I bought a used one for 80 bucks.

If its a newer vehicle this all will be under warranty3 yrs or 36000miles just by production date is on the driver door
