Question
2003 Cavalier - Heater / AC blower works fine but can not control air flow direction.Could it be Vacuum line? If so, easy way to check?
Thanks for the service.
Hi Larry, yes it is probably a vacuum line, the easiest way it to pull out the controls, but first go to the dealer and ask them to give you a photocopy of the hose routing and color code, then with the engine check to see if there is vacuum to the heater controls. also check for missing or blown fuses. I hope this helps you if you need more info just let me know. Regards, Keith.
