I need to find out which relay operates the keyless remote door lock/unlock function, and where it's located. A year ago when the car was at the dealer for major service I asked to have the problem (no lock or unlock with the remote) diagnosed, and the answer was a bad relay, but it wasn't in stock and if the idiots ordered one they never told me when it came in. Before I plunk down $120 for a replacement I'd like to open up the old one and see if it suffers from the bad solder joints like the RWD relays seem to.
