Was there any change in temperature?angelca1993 said:So today as we were driving our 2009 Traverse LS was acting up. We had the AC level on the middle speed setting and then the speed would go up and down by its self without the knob moving! It was weird. Has anyone else had this happen? ???
Pressurized or pressurization... not sure of exact wording.kawazar said:I have it happen but only when someone opens a door. I guess it increases the air flow from the fan. Once the door is closed I can hear the fan slow down a little.
