Had a vacuum problem with my vents for A/C in kick panel and under cowl not working as designed. I have checked engine vacuum,checked both servo's with a vacuum pump and they work as design. I then took heater control panel out and pulled main vacuum source lines off back and tested the black with orange trace vacuum line. Both doors work as designed when vacuum is applied.
Is there a way to test heater control panel? If i can get all to work manually leads me to believe something in heater control panel is bad but would like to try to test before drop $78 on new one.
