Re: [Chrysler300] Rear power windows sticky and slow

[Bill Huff <czbill@xxxxxxxxxx>]

Hi Jeff,

Based on my D, I can relate that all of the power windows were slow 
and needed help.  Actually the rear windows wouldn't move more than 1 
inch, even with help.  Lubrication of the window slides, etc. didn't 
help.  Probably a complete removal of all components would reveal 
some old lubricant/dirt buildup that could be cleaned off, but since 
this is not a body off frame concourse restoration, that won't happen 
if the problem can be solved otherwise.

I found that in my case, all of the gear boxes were bone dry and the 
gears showed signs of wear.  I cleaned them and re-packed the gears 
with good multipurpose grease.  At that point the front windows would 
work, although not with much enthusiasm.  The rears still didn't want 
to move very far.  I installed relays for the front windows, mounting 
them to the lip of the window mechanism opening.  Also ran a separate 
12 volt power feed from the circuit breakers to the relay 
contacts.  The front windows now move smartly.  I ran a temporary 
power  feed to each rear window motor and spent several hours 
(interspersed with long cool down periods) working the windows up and 
down with help by hand.  That is where I am at now, the rears will 
move all the way up and down by themselves, although there are a 
couple of stiff areas still.  I think more exercise and possibly 
installation of relays will fix that.  I am about to order a Gary 
Goers interior, so I have a few months to decide what the final 
decision will be.

For the fronts, I removed the winder mechanism with the arms.  For 
the rears, I worked in place.  In either case, for the 57-59 at 
least, there is a very strong clock spring that assists the windows 
up.  It must be secured if you intend to remove the gear mechanism 
from the spring/arm mechanism.  I can be a good finger or eye remover 
if allowed to fly free.

Your experience may vary.

Good Luck,

Bill Huff
