Question about 1999 Cadillac Escalade
We had our window down on our cadillac trying to find out why it won't start. We found out it was a dead cell in the battery. BUT before we got a new battery we jumped the car and while we were jumping the car there was a buzzing sound coming from under the dash. Now the power windows won't work, the radio won't play and the windshield wippers won't turn on. What relay would cause this problem or is it something else.
Why was it necessary to "jump" a car with a new battery?? You probably have overloaded the electrical system,, this may be one for a professional...

CSP, It sounds like you have a vacuum leak that is causing the IAC ( idle air control ) motor to move in and out trying to control the idle. Check all vacuum hoses on the engine for disconnect, cracked or damaged. If the hoses crack when you bend them, they need to be replaced.
Let me know what you find and we can go from there.

Thanks for the advice about the BCM. The BCM is located under the center console. There are a total of 4 screws keeping it attached. Two in the center by the CD changer and two under the drink holders. I found that the harness on the BCM of my Escalade was connected but had issues. I could push or pull up and down on it and my cars functions would go on and off intermittently. I grabbed some electrical tape and zipties and tightened up the wiring by attaching it to part of the framework on the console. PROBLEM SOLVED, at least for now. By the way, the Cadillac dealer told me that it is RARE that they have to replace these BCMs. They usually need a re-program that costs around $100.

Sounds like the PARK SWITCH within the WIPER MOTOR is at fault, Only way to beat it is relay the motor. Hope this helps
