Having problems with your 1999 Ford Expedition ?
My 1999 ford expedition power windows, sunroof, flip windows, rear windshield wiper, doom light and running lights all do not work. what should i do?
All of these components are controlled by one central electronic module commonly called the BCM or body control module, this module has self testing capabilities, a Special scanner called a NGS (new gen star tester) is used by the Ford dealer to run the module through the required functions tests, from the sound of it the BCM in your truck has completely failed and will need to be replaced, although replacing the BCM is not a big job the problem is the module needs to be programmed because it contains the security system circuits as well, and when the new module is put in you will not be able to start the engine until the new module is learned to your keys unique code.
