To find the modules controlling various electrical functions, you'll need to consult a wiring diagram for your specific 1999 Taurus. These diagrams will show the location of modules like the:
* Body Control Module (BCM): This is the most likely candidate to handle many of the functions a GEM would. It's responsible for controlling various body electrical systems. Its location varies slightly depending on trim level and if it has a certain package, usually under the dash or in the center console area.
* Powertrain Control Module (PCM): This controls engine and transmission functions.
* Other smaller modules: Depending on the options (power seats, sunroof, etc.), there may be additional modules controlling specific functions.
To find the BCM (or other relevant modules):
1. Consult a Repair Manual: A Haynes or Chilton repair manual specific to your 1999 Ford Taurus is your best bet. These manuals will have detailed diagrams and instructions.
2. Online Forums: Search online forums specific to Ford Taurus owners (like the Ford forums on sites like ClubFord). Other owners might have discussed the location of modules in their similar vehicles.
3. Ford Service Manual (if accessible): The official Ford service manual will provide the most precise information, but it's usually only accessible through a subscription or professional repair shops.
Without knowing the specific electrical function you're trying to diagnose, it's impossible to pinpoint a single module. Remember to always disconnect the battery negative terminal before working on any electrical system in your vehicle to prevent short circuits and damage.
