99 cadillac catara problems

scan the radio

Likely a computer problem, very unlikely a "short."

Going to have to tell us what you have done or tested
so far & how

Have no idea if you ever worked on any vehicles

Hi, I believe this may be a fuse problem. The owners manual will show you the fuse box or boxes locations and what each fuse powers. If it is a blown fuse it may be that something in the trunk pinched the wire and shorted it. The wires as they run from the body to the trunk lid is a good place to check for a pinched wire or short. The unlock solenoid may be the culprit if it shorted out, just a possibility. If a fuse is blown, replace it then check to see if the brake light works. If so then try opening the trunk electronically, if the fuse blows again then you know that circuit is the problem. Good Luck, Jim

Fuse

Its the K134 Multifunction Module. Its located under the drivers side dashbaord...

Just bought a 1999 Cadillac catera and i have a problem??
, both the buttons on the dash and remote are not able open the trunk and gas door. The radio is not working also.
What can I do?

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

Did you recently have a loss of power to the car? change the battery? if so, you need to reset your system. My husband and I just figured this out this weekend. His sunroof hasn't worked in two years and it turns out you have to reset all the power options in the car. Google 2000 cadillac catera %calibrate ETC% loss of power, you'll find the step by step instructions for recalibrating the car's computer and resetting the power options
