351mach11647545510 Posted August 6, 2012 Report Share Posted August 6, 2012 So I had to drive the avalanche today for the first time in months (new tranny also ordered today) but i've had a growing concern about the body control module going bad. The Service 4wd display has randomly come on along with the 4low indicator flashing sometimes and the climate control has more frequently went crazy. It will blow heat when you have the a/c on but will work fine most of the time if you turn the truck back off and on again. It has a digital dual climate setup. I'm curious what all the BCM controls and if this sounds like the culprit or 2 seperate issues. Quote Link to comment Share on other sites More sharing options...
AJ Posted August 6, 2012 Report Share Posted August 6, 2012 Two different issues. Needs a 4wd switch and a temp door actuator. Quote Link to comment Share on other sites More sharing options...
