Dash air - warm

[Old Scout]

Rdownward,

Couldnt resist the opportunity to discover a "new" solution for what aflicts our 03 dash A/Cs. I called Doug--and yes, he simple capped-off the fan control loop. I dont think this is the best solution--as a minimum your engine will tend to run a bit cooler which impacts MPG; and the fact that the engine fan motor is equivalent to about 25 hp, will also have an impact on MPG. Keep us posted on how this turns out.

PS--working with a auto AC fabrication shop here in town, I am thinking about installing a second evaporator [in series] in the space above/infront of the differential, to include an electric fan tied to the dash ACs on-off. This solution is done all the time for stretch limos, mini-buses, etc. If I go this way, I'd remove the aforementioned bypass valve that is tied to the aux freon pressure sensor.

Old Scout,
I did something very close to what you are talking about to our 99 alpine and had great results. The one thing I did different was to take the condensor that is in the radiator area and moved it to under the entry step and installed an electric fan.

Our dash air was not blowing cold air, so we took it into a service facility in Canon City, Colorado. Turned out that there was a worn o-ring on something in the rear of the coach that was causing the freon to leak out. When he repaired it and filled it up, the air coming out of the vents was at 32 degrees (as shown by a laser thermometer). Still cools great one year later.
