Power Seat Switch 1960-62
by John Grady
I had
occasion to get into this pretty good, as one direction was not
working. I spent some time on it and thought I would share the
experience. I had cleaned and rebuilt the power seat clutch mechanism
previously and it worked OK. The FSM is good on that as far as
keeping things synchronized.
The switch is
a very rugged switch inside and there is not too much to go wrong.
The sliding copper spring loaded shoes connect wires to 12v in
various clever ways. The system has three clutches, two motor
directions to create four motions.
Inside the
switch, I could find nothing wrong! The contacts look like new. I
think what happened is oxidation on one of the contacts. Next time I
think vigorous working this switch back and forth 50 times will fix
it! Slide type contacts should clean themselves. I added a drop of
75 weight oil where knob shaft goes in, and it all moves much better.
After
reassembly, I noticed the solder job by factory was very poor where
wires attach to tabs on the back. I resoldered them and the switch is
working OK now. This might have been the problem.
I hope this
helps somebody frustrated by power seats. One more 300 item
down!
