Crunching noise - passenger window
« on: June 11, 2014, 10:49:55 PM »

My window has started to make a crunching noise as it's going up and down.  The window got stuck in the down position but I was able to pull it up as I played with the window switch (pushing it up/down repeatedly).  What is making the noise?  The window is in perfect condition and the window switch still works.  Is it the regulator that everyone replaces or could it be something else?

Regulator.   That noise is the steel cable kinking and chewing up plastic parts.  If its up, leave it up until you get it repaired, eventually it will fail in the down position..Chris

Yep, it's the regulator. The cables twist, bind, snap inside and make all sorts of noise. I need to do my driverside AGAIN

One of the folks here played around with using a motor assembly from I believe a Ford Escort? (I believe you have to integrate it with your existing regulator) Theyre available aftermarket at least. Worth looking into IMO

Thank you, I remember that post.  I think my motor is working fine but the regulator is not.  Is it possible to just replace the regulator?  Or fix it?  Or does the crunching noise mean there are broken pieces in the regulator?

For all practical purposes, the motor is integrated into the regulator assembly, there are no open gears that allow easy motor replacement like in many other cars.  There are 2 steel cables in there that are wound onto a plastic spool.  Once the cables start kinking (crunching), they don't wind onto the spool correctly anymore.  The cables would have to be replaced, and the spool may be so damaged that even new cables wouldn't work correctly (new spools are not available).

It is a challenge to repair these regulators.  Having a cache of spare used parts is required since none of the parts that usually break or get damaged are available new.

Buy a rebuilt regulator assembly if you can rather than one advertised as just used.  They are all used, but the rebuilder repaired broken items, and probably repaired/re-enforced parts that eventually break.  James Whitt at jewhitt2005 at yahoo dot com is an accomplished rebuilder... Chris
