OK, the service manager called me back and gave me pretty silly sounding answer. They said GM does not want them swapping parts till the did some programming (I understand that part). so what he says they had to do was push the dash buttons (4x4 lights) in a sequence for "something like 50 times". Now they want permission to drive it 50 miles (wonder if they will ensure the fuel tank is at the same level as it was when I dropped it since they will do that to the rental). This sounds to like they did nothing today because they could not get it to error while they had it. I can not imagine having to press buttons 50 time in sequence to reset the PMC (oh yeah that is the new part they claim may not be talking to the other parts). This is beginning to remind me of why I have not bought a GM in 15 years </div></BLOCKQUOTE>
It's actually a Borg-Warner engineer telling them about the 50 cycle issue. B-W is under the impression the 4wd issue is due to electrical/feedback contacts not being cleaned during xfer case assembly. The rationale behind the repeated cycling is to attempt to clean the contacts. Jury is still out...
