Question about 2000 Ford Expedition
On that year/make/model there is no "valet" switch to speak of, and the factory alarm system can not be disabled without 5 times as much work and wiring as you would put in to fix the current problem. There's a good possibility that you have something simple like a failed GEM module, but without a complete diagnostic check, throwing parts at the problem won't fix a thing. In order to bypass the alarm you would need to rewire the entire databus system and then reprogram the modules to correspond with the removal of the anti-theft system, if there even IS a program you could install to let the modules know there is no longer an anti theft system in it. My suggestion, get either a good local independant on it, or dealer.
