to remove the VSM, remove the center dash/radio. The unit itself is attached with 2 bolts/screws. The one on the right is a PITA. What I did on my truck is to reroute the VSM so it's just hanging down on the tranny tunnel and drove to the dealer with the new VSM sitting on the passanger seat in the box. The tech just swapped it and programed it using the buildsheet I had with me. (they usually download this info from the old VSM - mine was totally fried) If you don't have a buildsheet the service guy can/needs to print one from their computer.
'02 CC DRW Lariat 7.3 Auto
ps. There was no error codes stored in the system...the original problem on my truck was: auto headlights not working, inside dome lights working sometime, radio would stay on after engine off and door open, doors locks not working properly with my remotes....
pss. I just looked at the wiring digrams for the '02 and flashers, horn and doors are all somehow interconnected thru the VSM. I'm no expert but I would say you are on the right track.
