So we purchased a 2000 Bravada for a good price. The the dealership
included a powertrain warranty with it which covered the broken sunshell
3 days after we purchased it.

We noticed on Good Friday that the SmartTrack isn't working also. Took it
to the shop and they found a few fuses that were out and replaced them.
One of them must have been for the SmartTrack and now it's engaging
but it won't disengage. They tried to hook it up to the computer for the
transfer case and was unable to get it to talk. They want to replace that
computer. Is that the right way to go or does anyone thing that it's the
motor/actuator. We were told that our car didn't have a motor/actuator
also??

Thoughts??????
