some thoughts from a guy who has rebuilt his entire front AC system...:

1) Coolant might be empty or extremly low
2) (sad your coach is a '06 and AC has not worked for several years... wierd!) If your clutch engages and disengages properly and obvoulsy your dash fan blows air (just not cold).... then i would take a stab @ your coolant. Evaporator fan should also kick on and off periodically but the coolant prolly needs to be charged. Sheesh a 2006 coach and dash AC goes out approx 2009? Maybe a leak?

P.S...: Dash AC to me is EXTREMELY nice to have working properly and is EXTREMELY expensive to repair. Most people just leave them broke but not me. LOVE to have cold air blowin' on my [moderator edit] while sippin' a cold one & lopin' down the freeway...

Air Conditioning

Footdoc, the front air system does two things; it provides heat from the engine coolant and it provides air conditioning from a freon system just like in a car. The coolant level has nothing to do with the air conditioning part of the system, and many owners shut off the two coolant valves on the motor to keep hot water out of the system in the summer. The two most common problems are low freon charge due to a leak in the system, and vacuum problems with the control doors that guide the air to the various vents. In default mode, all the air will go to the defrost vents. If that is what you find, then it is a vacuum leak in the control system. If the air is directed properly when you rotate the switch and the air is not cold, you should take the coach to an airconditioning shop for evaluation. Very few backyard mechanics like myself have the tools to service the freon system. Hope this helps. DACOTAH

If your EVANS control valve is not closing off the heat portion of your heater people have added a BALL VALVE..

Here is information on EVANS VALVE.

After rechecking, the ac clutch is NOT working and the fuse is ok...and I think I see evidence of an oily residue at a hose fitting...must be the culprit

Most systems have a hi/lo pressure switch to shut off the compressor for safety. It is usually on one of the high pressure lines, and looks like an oil pressure switch except that it has 2 wires rather than one. It is 12 volts so it is safe to jumper it quickly for a test. If the compressor comes on when you jump it, you are probably low or empty on freon. DON'T RUN IT FOR MORE THAN 5 seconds with the jumper. Any competent A/C shop can recharge and leak test the system.

The outside (Condenser) fans may be operated by a relay which turns them on when you select A/C or they may be operated by a T-Stat, if the condenser (or radiator) does not get hot enough, NO FAN.
