Hi,

Re the stereo your car can either have the ETR AM stereo/FM stereo w/cassette- (standard) or the optional Bose® AM Stereo/FM Stereo, Cassette Tape, Single Slot CD with or without the 12-Disc CD Changer. A bit complicated wiring due to the anti-theft features interlocked with the on board body control module.

That you have posted likewise problems with the fuel tank lid indicates a possible problem with your middle console (which includes the trunk release). There would be on occasion similar issues with the electric door locks.

"...The first difficulty in diagnosing is that there are no body type trouble codes in your car. These cars are really hard to simply check wires and see where there is not voltage due to the complexity of the wiring systems. The body control module is involved in all of these operations. These have seemed to be a serious problem with these cars from what I have seen. Really the first step in repairing this car is to have the car scanned for trouble codes. Not the home/user version but the dealer/pro. These are the only tools capable of checking body failure codes.

The fuel door release, trunk release, and door lock problem, that all of these items are power off of the DOOR LOCK fuse #28.

As far as the radio goes, pls check fuses #8, #14, and #26. These are all power sources for the radio. If the display is totally inoperative, the very first step is to check the system for trouble codes. This is what is very frustrating with these cars. It has removed all the old tactics of wiring/voltage testing
..."

Here is an electrical diagram which may be of use to you. Most of the additional information came from here.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Sir,

Did you get the rotors cut you might have an high spot on them; and make sure the ware sensors are not rubbing and use a lot of brake clean

I believe the problem is a faulty a/c computer module which costs around $400 to get done at the dealership.Remember, there is an emergency trunk latch behind the rear seats and to fix the fuel door problem, just remove the latch inside the fuel door and you don't have to ever worry about it again.

Thanks
good luck

Wiring diagram for cadillac catera 2001 need to download free diagram radio and stero shut off occasionally which also locks trunk and fuel door


It is the BCM (Body control module). The radio is married to it via the serial number. You need to replace the module (lower right kick area, pass side in front of front door, behind plastic...aluminum box), and have it programmed to your car through a Tech 2 diag system.....dealer...this unit controls just about everything apart from the brakes, engine and tranny which all have their own computer. You probably have issues with the sun roof if you have this option.

Gas tank won't open, trunk won't open, radio stopped working, left tail lamp won't work


It's the body control module. It's located under the dash to the left of the steering column. I had same problem, went to the junk yard and bought one and the problem went away. Dealer wants $600.00-700.00 for the BCM, I paid $30.00
