RE: [Chrysler300] 300 K bucket seat rear flap

["'Rich Barber' c300@xxxxxxx [Chrysler300]" <Chrysler300-noreply@xxxxxxxxxxxxxxx>]

I had a number of helpful hints on a RH power seat in our ’64 300K convertible that would only move forward, not backward.  Original message below.

 

I’d like to hear from anyone with clues on servicing the RHS switch once I do get it out.  The switch will drive the seat forward but not back.. I’ve just read the service manual direction to pop the switch out using two screwdrivers and have also read the suggestion to just cycle the switch to clean up the contacts but that does not seem to work.

 

By removing the switch and a short 3-wire bundle between switch and motor, cleaning the contacts (they all looked OK, giving the spades a 15-degree twist (thanks Ray) and reassembling the wiring, the motor returned to proper operation without removing the motor.

 

Things I learned with this project:

It pays to go to those with more experience in resolving unusual issues (I really already knew that).  Special thanks to Ray and John for help and encouragement

It is hard to full the connectors apart. I ended up clamping one connector in a vise-grip and prying the other connector off using the vise-grip jaw for leverage.  Whatta wimp.  

My hands, fingers and the hide that cover them are not as strong as they were in 1964.

It is possible, but difficult to remove the power seat motor wiring and even the motors from underneath the seat.

The power seat switches are held in their places in a little steel frame by four flat spring clips-two on each end.  The switch is released from the frame by sticking two medium screwdriver blades into one end of the switch (there is a little notch to guide the screwdrivers) to release the two flat springs on one end.  One can find these springs by using the screwdrivers to feel the flat springs which will give a little as they release.  You run out of hands about here. The switch can then be rotated out of the frame.

The letters “TOP” are subtly embossed on the top of the chrome power seat switch frame (this embossing is also present on the power window gang switch and the three other single-window switches (concours judges??)).

One should carefully note the routing of the wiring under the seat before removing it.  A mistake might lead to a dead short and (hopefully) a popped breaker.  I think I have it right by running the harness under the track..

It is unlikely that one of these small reversible DC motors will malfunction in only one direction.

 

Really glad to be able to share pix.  I tried to resize these so here goes.
