Post back any and all codes no?

Thanks for your reply.
I had the Codes pulled and it showed a B2725 which indicates a malfunctioning switch.
I replaced the switch with a new one and the problems (as well as the B2725) remained.
I ended up replacing the Transfer Case Control Module a couple days ago with a used unit (same #) and it fixed the problem.
I've read the a bad TCCM will give erroneous/false Codes when they go bad. Also, the TCCM's in late 90s early 00 GM 4x4s are known to go bad quite frequently as well.
