I am currently replacing the vacuum hoses or attempting to. Because the air is not blowing through the dashboard vents at all. Only through the side vents and the defroster. However, in taking off the blender actuator I see that its out of alignment and the only videos I can find are for a 7 prong recalibration. Can you help me? |

There is no procedure for recalibrating those actuators according to GM Service Information. I have also never had a need to when I used to work on them regularly. I have repaired broken vacuum lines several times over the years. I found it best to replace the entire supply line from the engine to the vacuum reservoir and usually a few more around the heater control valve area. |
