Mike;

I found the following p/n under "Selected: 2002 TROOPER - ELECTRICAL - SWITCH AND RELAY; INSTRUMENT PANEL" on the MyIsuzuParts.com web site. Figure 8-25, image #6

" 41 SWITCH; BACK DOOR LOCK 11-1999 and LATER"
Part number "8-97081-773-0"
Also don't forget that Acura and Honda sold rebadged Troopers so you might have luck at one of those dealers.
Give Merlin a call @ St.Charles Isuzu above, I have had very good service with him in the past.

Bob
