RE: [Chrysler300] power window help



If like 60 , two field windings. You put 12 volts from one wire to motor
case , NOT  between the two wires. One field is wound opposite to other so
only one field works at a time (weird) ; but if you do not do this, then
you have to reverse the polarity of armature or field (only one!) to reverse
a DC motor, takes a relay,  lots of wires come out for wound field, 4 plus
relay, power lead and command leads. ( some can be common)  . But original
300C to F G design ( at least) works ok, just means bigger motor , ground
motor;  12 V to one is up, 12 to other is down. Easy to test. I get into
this as you may be testing it wrong ? Or have wrong motor. I do not know
which type 300K has, but probably first type. Where did you get "a motor" .
A heater motor looks like it but will not work at all. 

Later power window motors have magnets in them, no field windings  so you
cannot do this . On those you swap + and - volts to reverse ( relay or
special switch with 6 pins (vs three to our first type) .

Good luck, 
John

Hi Out there,
A little background before I reveal my problem. I have a 1964 300k
convertible power windows.  Front passenger side stop working all others
work as they should.  Found motor frozen  Replaced it greased gear box,
motor and gear box both turned fine.  Tested switches they seem fine.
Hooked up motor only and all worked fine. With the switch it seemed to run
in one direction when switch pushed up and another when switch pushed down.
Now my problem!  Hooked up gear box all turns easy by hand.  Tested motor
with gear box and it only works in the going up.  Nothing when I hit down?
Any enlightenment from someone out there about this conundrum would be
greatly appreciated.
