Re: [Chrysler300] electric window motor removal ?

[Ray Jones <hurst300@xxxxxxxxxx>]

You are very wrong, largely dependent on if the assy. in in the door  
with the window attached or on the bench.
The purpose of the large coiled spring is to counter-balance the  
weight of the very heavy window assy.

With it in the door, it's not a big problem, you must watch as you  
remove the motor for the window slamming down and catching you when it  
does. Stick a piece of wood in there, cut to reach from the bottom of  
the door to the bottom of the window so it can't slide down.

If it's out, when you take the last bolt from the motor and pull the  
motor off the assy., that spring will uncoil, swinging the window arm  
violently around in an arc. I know this from personal experience,  
having a dent in my skull/forehead area. I thought my skull was split  
open, but was holding the assy. loosely in my hand and it flew across  
the shop. If it had been in a vise, .....

I've used vise grips, but prefer to drill a hole thru the assy. frame  
and thru the big arm and install a bolt to secure it.

It doesn't matter where the arm is as you re-install the motor, it  
just runs backwards and forwards until the switch is released.

Please correct me if I'm in error - but I had thought primary danger -
relative to spring energy was taking regulator apart - not removing
motor - and as I recall it had less energy in one position - but the
reason for vice grips would presumably be to keep an "up" window from
falling down due to gravity - or is there stored spring energy there  
too?
