{Chrysler 300} Power Window "Half" Blues

To all 300'ers:

First, thanks to those folks who have given me tips to get me this far. Bottom line: My passenger rear power window on my 1965 Chrysler 300 only moves with the switch in the down direction. When the switch adjacent to the rear window is hit to raise the window, a click can be heard at the motor and the dome light goes quite dim, but no movement at all. Now for the history:

1) The master switch connector on the driver's door has been replaced thanks to Murray Park (the old one was cracked). I took super care to crimp all wires tight and properly. That being said, there is no activity from that front switch to the right rear motor. This condition pre-existed the master switch connector replacement. All three other power windows work properly from either the master switch or the window switch.

2) The power window motor in question was just "rebuilt" by a local small motor company. After gooping the assembly tracks, regulator and rollers with grease and silicone , I hooked up a spare PW connector wire set to the motor and to a small 12V tractor battery. I am able to get the window both up and down doing this.

3) The PW switch at the rear window has not been replaced, but to me it does not seem like the switch would cause the problem I describe above.

4) After tracing and inspecting wires from the rear up to the front dash where the majority exit to the master switch, I have determined that there are no visible rips or tears in the harness tape between the two. The exception could be within the door-to-body wire shield, where I cannot inspect the wires.

My best conclusion is that there is some "dead short" between my two PW switches. My manual's wiring diagram is simple in this aspect...the two switches are directly connected with two "directional" wires. A third common wire leads directly from the instrument panel wiring. That wire must be fine or my window would not work in either direction. I am thinking about replacing (with splicing) one or both the two directional wires along the entire length to see if that corrects the problem.

If anyone out there can understand this and can either agree or offer another idea, I would be most appreciative.

Sincerely,

Ron Klinczar
