Hi Guys -

Here's a weird one...

When I have the blower on (air or heat) and it's going through the panel, if I hit the accelerator the air STOPS coming out the panel and comes out somewhere else.

I have replaced the blend door actuator, the vacuum control motor for the defrost/panel (since I have not had any defrost controls at all), and the floor/panel vacuum control motor works fine.

This problem existed before I changed any of the above parts, but the air did not come out any of the 3 main exits (floor,panel, def) that I could determine.

Thanks,
Mike

 

You have a small vacuum leak on the line that runs from the engine compartment to the control head or in the control head itself.
