02 3500 crew 8.1 w/ YE9 Doors always lock/unlock crisply when put in/out of Park.
From either door switch, operation is erratic. never crisp like shifter. both switches
were replaced (GMP). I do not have a key fob for it, and wonder which key fob it takes.
Only a dealer can query the VIN to key fob? Did all C3500's have remotes?
TIA
