Its always something . Cruise started failing this weekend. It will set but then slowly slow down, I looked at hoses going to the diaphram thingy and the seem good. I'm sure this is a common problem, what should I check? Thanks!!!
Went for a cruise tonight and the vents wont switch from floor to dash. Considering just replacing all the vacuum lines. Can you get thoses little check valves at a parts store or must they be ordered online?
Thanks Steve!! The issue I'm having is the door wont change position to change air flow from floor to vent, it will turn AC on and off. If this switch is bad would you hear the vacuum hissing in the cabin? I assume there is a hose leading into the switch? If thats the case maybe its broken/leaking in the engine bay causing the heater control and the cruise not to work. I'll dig into it tonight. High 90 degree temps and high humidity here, need to get this AC working
