Question about 2005 Chevrolet TrailBlazer
Ok, my problem is that I have air blowing through the defrost and the floor vents and NONE through the dash. I am still looking for a solution. I talked to a GM tech and he said it was probably the actual Control Unit or it could be an actuator that controls the vent doors. Now the problem I have is their are a total of 5 actuators on this vehicle and 3 of them are very very hard to get to. Should I spend the money on a new control unit or should I tear my dash into pieces looking for the actuators?
Is this a possible vaccum switch issue?
I'm having the same problem, I changed my battery yesterday and all of a sudden my dash vents are not working, I've been told its either a relay switch out or a vaccum hose issue, hope you find out how to fix it if I do I'll post an anwser.
