Ford V10 Fleetwood chassis Bounder 36' one slide - Dash air not cool - compressor clutch controlled by a cycling switch at the end of a 30" boron tube that ends inside the evaporator coil. Switch is supposed to be closed and only
opens if the coils are cold enough to freeze the condensate coming off them.
This switch with the tube is considered "old school" new electronic switch controls a relay which controls the clutch. Dealer does not know what this part is so I did some investigating and found a suitable replacement at Napa Store part #207501 for $45.83
delivered to my home. New switch is also adjustable like the old one. If contacts check closed, the reason for air not
being cold my be low Freon charge. Hardest part of replacing switch is opening
the evaporator compartment so old tube can be removed from the coils and
new one installed. Switch can be located near or attached to the evaporator
compartment either inside the coach behind the dash panel or in the engine
compartment near the evaporator compartment. My results after new switch
and 1 can of Freon 50 degree at idle and 45 degree
at 3000 rpm sitting still.
Happy cool travels to all!
