Re: [Chrysler300] Planes, trains and automobiles

One hesitates to say "All" , but most any modern car has the A/C  work in Def mode  just to  dry the air being blown over the inside of the windshield. My 2001 Dodge  Ram and Dakota  do it. Been around for many years.
Since it is essentially an air loop, from the blower, out the vent, across the windshield, down under the dash into the blower and so on, the A/C dries out the moisture blown off the windshield.

Webster rules and says: 





noun: motor; plural noun: motors

1.    1.

a machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts.


Engineers and purists must live with consensus.  Alan asked what does one call the turbine that drives the generator at the dam.  It is a motor, as is the air-powered device that the dental hygienist uses, the windmill that pumps water, the treadmill that the animal trots on to power another device, a steam engine and that belchfire 8 in our brutes.


It was interesting to learn that there is a filter in the sealed pulsation dampeners/mufflers on either side of the air conditioning compressor.  On the suction side, it is a final filter to prevent solid trash from entering the compressor.  It could conceivably become plugged if some extenuating circumstance created a lot of solid foreign material in the evaporator.  Similarly, if something broke loose in the compressor, a filter on the discharge side would prevent the trash from travelling downstream and plugging the capillary tube or expansion valve.


Last point:  I have the HVAC switch out of our ’64 300K and it is only set up to operate the A/C compressor clutch when either the MAX COOL or FR COOL buttons are pressed in.  Pressing in the DEF button does not actuate the clutch.  There is also no apparent low-pressure cutoff or thermally-controlled switch in the clutch circuit.  You press MAX COOL or FR COOL and the A/C compressor will be engaged.  Later design resulted in using the A/C system to dehumidify defrost air and inserted a protective switch in the clutch circuit to disengage the compressor in case of loss of refrigerant.
