Dash Air '97 BMC 40' - Michael Brody - 07-02-2005 07:47
My dash air has suddenly stopped working. I have checked the center fuse
panel -- all are ok. The condenser fans are running as are the dash fans.
The compressor clutch does not engage.
The air worked fine Thursday morning and wouldn't work in the afternoon.
Ok all ye gurus, what do you think.

Mike,
I'm no guru but I suspect either a loose connection in the wiring to
the compressor or possibly a loose/slipping belt. If the wiring and
belt(s) check out you may have a clutch failure. I too await word
from the gurus.

Hi Mike,
I just had the same problem and it turned out to be the compressor
clutch coil had developed an open. New coil was $38.... Clutch was
okay. Disconnect the wire that feeds the clutch and see if you have
12 volts at that location with the system on. Secondarily, check for
continuity thru the clutch coil and third, to make certain, run a
jumper direct from the battery to the coil wire and see if it
activates the clutch. If not, remove the clutch and take to an auto
A/C shop so they can match the coil.

George, With only one coach to maintain.
Congratulations on the sale. What will you do with all your spare
time?? We still have two by choice, The Bird for long trips and a
smaller Dodge Roadtrek for short trips. We average our total on the
road fuel mileage, it really boosts the Cat fuel efficiency

George,
Excellent advise, as usual.
IF the clutch engages after it's jumpered with battery
voltage, the next step would be to check the pressure switch(es).
There's a switch in the high pressure line to shut down the
compressor after loss of refrigerant as a safety feature.
It will be a small aluminum sensor in the high pressure
line somewhere with 2 wires going to it. If you can find it,
remove both wires and hold them (or jumper them) together. If
the compressor clutch activates, either the switch is bad
or you've lost all the freon. If the suction pipes get cold
when the compressor runs, you need a switch.
Some systems have a 2nd switch on the suction (low) side
also, but it's rare.
ALSO, congrats on selling your bus. I was going to see if
you'd finance it for me at 10 bucks a week, but it's too late
now. Let me know if the deal falls through. LMAO!!

Bill,
What a great idea - averaging the mileage 8-) !!! We are trying to
get everything out of the house so we can get it on the market.
Astounding what you can gather in 35 years... Once we get on the
road, we will have only the Bird and the Cad Fleetwood but averaging
would help. (the Cad averages 26 mpg on the highway.) I'm looking
forward to having time to work only on one coach and nothing else.
BTW, John and Barbara Ely sopped by this past week and we had a short
but enjoyable visit with them. They are wonderful people. Hope to be
seeing more of them on the road.
