So the problems that I had previously described have gotten worse, and I believe they are related. When I started the truck, all hell broke loose. The door locks keep trying to lock, service just about everything shows up in the display. The speedometer was very intermittent as were all other gauges, cutting in and out, with very audible ticking noises from somewhere in the footwell area, that sounds like relays clicking on and off. Furthermore the ABS light and every other light were on and the truck would only drive in limp mode, which I had to do to get home, some 30 kms. At least the heater worked in the -30 celcius weather.
I have read that the negative battery cable can be a culprit or the body control module. I played with the negative battery cable but it did not seem to affect anything. I'm reluctant to order and change the cable if the body control module is the culprit.
I have found similar posts, but the resolution seems to be unclear. One such post is this one:

This thread was linked in another one related to the issue, but the failure mode in this instance was a completely dead truck, which mine is not. It starts up without issue, and can drive just fine, in limp mode with everything going crazy. http://www.tahoeyukonforum.com/threads/intermitent-electrical-problems.63936/
Appreciate any feedback or pointers on this one.
