Okay, started to debug some of these electrical issues. Took 2005 RL to dealer for Driver 1 Fob, programming, and key. When I bought car, only 1 key was with it, and it was missing the cap (?). No fobs.
Dealer couldn't program key - short somewhere. Dealer replacing passenger door handle for starters, and I bought ebay Nav drive for 350.00. Waiting on both parts.

Symptoms:

#7 fuse blows when it's in.
Electric Locks Nada
Nav Screen Black
Gas cap release Nada
Hi-beams Nada

Power Steering pump is leaking, going to do that repair myself - New Nav drive and definate short in Passenger handle is starting point.

OEM or Non-OEM Pump?? Opinions?
