Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Ok, please reply to the open thread rather than opening a new question each time.
This is not just a simple switch assembly, it is in fact a module. The module comes basically brain dead, and the programming, done with a interface module such as the GM MDI connected to the GM programming server is what programs the module to your vehicle to operate. Sadly there is no way around this and no possible way to do this without the items I mentioned.
