I have an 02 escalade and my auto leveling system quit. I was gone for two weeks and since I've been home, it hasn't worked. The only fuse I could find that had to do with it was the one marked stud #1, and it was good. I noticed there was no fuse in a spot labeled a.i.r. system. Can't figure out what its for or why its empty.

limited info generic answer ---tow--haul switch doesnt have auto level thats a separate system --have scanned for any codes active or pending check fuses relays and sensors

Turn up the volume? Maybe mess with the balance and fader switches if the volume is up. Has anything happened with this problem? Example, a kid was in the car just pushing buttons? If nobody touched anything and it was working then quit,
check the fuse for your cigarette lighter. An Escalade probably has a fancy sound system with an amplifier and I believe that fuse may control the amps power. If your lighters won't work to say, charge your cell phone. (Check all power sockets) then it's likely the fuse is blown. Your owners manual should tell you which fuse is for the lighter. May also be a fuse for the amplifier. Probably in the underhood fuse block. 25 amps. That gives you some things to check. Let us know how it comes out.

fuse or relay bad..

could have bad battery ground cable or have starter solenoid and starter checked out at any auto parts stores.

It will most likely be a poor earth issue, make sure the earth lead between the battery and the body is good and clean and check the one between the body and motor.
Poor earth connections cause excessive current draw and will blow fuses.

Well, first of all, did you fix the problem that caused the fuse to blow? Have you scanned you Antilock Brake System (ABS) module for fault codes? Since the computer is the one responsible for turning the light on, wouldn't you think that the computer would be the one to ask WHY it has turned the light on?

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

HAVE COMPUTER FLASHED MAKE SURE BATTERY VOLTAGE IS UP AND THERE ARE NO CHARGING PROBLEMS

I would suggest you check oil levels etc. Generally these cars suffer from the air mass meter / air sensor problems aswell as coil problems too. Did you ever get a solution to the problem?
