Lost & Confused !! Whats wrong now ?
wow, serial rape. First the body shop, then the "mechanic", or as we call them "parts changer".
Spend a few bucks, and get the Mitchell online manual:
Mitchell On Demand repair subscription
Then you have the full Factory Service Manual, complete wiring diagrams, ALL of the TSB's, other mechanics tips & tricks...
I am always amazed by the so called mechanics that are actually doing OJT on your nickel.
An electrical problem that bad should be fairly obvious. Get a decent DMM, and start looking at the affected systems from the wiring diagram.
All it takes is patience, and attention to detail.
