Well I found a mess behind my mode switch...thanks for all the help with it guys. The brown hose was connected into the orange hose at it's T junction (basically system was vacuuming on itself)!!! So once I hooked up the brown hose correctly the amount of air now blowing out of the vent tripled!! Now my problem is this: In the parts manual it shows that the orange vacuum line operates the re-circ and the water valve. I am missing the hose (or simply can't find it) that operates the water valve that connects into the T junction. (I capped it off until I can find the hose) Where is the vacuum hose that operates the water valve routed as it approaches the mode switch? Also where is the heater water valve located? Hope all of this makes sense... Michael
