Having problems with your 2002 Chevrolet TrailBlazer ?
I have a 2002 chevy trailblazer. Yesterday my heater worked fine today I had the battery replaced and now I notice when the heater is turned on it is only blowing heat on the drivers side. Defrost floor and dash vents. But on the passenger side all of these vents are blowing cold air. Yes I have the manual climate controll levers slid into the up position. How can i solve this problem and might it have anything to do with the battery change?
Needs to be reprogrammed with a TECH 2 at a GM dealer.
