I just bought a commodore vl n/a and the air conditiong is stuck on the front demist duct. I think it might be the vacuum tube disconnected off the motor or wherever the main vacuum tube goes. Could someone please tell me where the tube conects to the vacuum source or suggest another way to fix it.....thanx :?
yeah it will either be the one on the back of the plenum chamber that feeds the auto and heater or it could be the one that connects to the big sphere under the front right of the bumper.
