Vacuum pump
Just inside the front "hood" on the drivers side of my MC is a small vacuum pump that appears to be for operating the ac/heat controls. Mine runs constantly when the heater control is turned to "off" or to "max AC". When I turn the control to one of the other setting such as "AC" or "defrost" air then I can hear the controls operate and then the vacuum turns off. It seem to me that it should only run as long as it is changing controls
I have a picture but I am having trouble getting it off my phone. but there is a fitting on the pump where it looks to me like a vacuum hose should have been attached, but I can't seem to see any loose hoses around to attach to it??? I haven't crawled around under the RV to see if it is hidden below my site line. There is one vacuum line attached to the control running up to a round control under the dash on the firewall.
if any one has any experience with this I would appreciate your help
