Another minor annoyance. The passenger side power window will not lower
without a little push-down help. It will elevate, however. It seems
that the motor is weak on lowering. What might be the likely culprit(s)
and how many Ben Franklin's will be required to fix this newest reported
Thanks, er, thanks Tegger :-)
The lube goes in the "run channels". These are the black-felt-lined slots
that guide the window edges as the window runs up and down.
I should have asked first: Is the window reluctant to lower from ANY
position, or only from fully-closed?
If /only/ sticks at fully-closed, then it's sticking in its channel at the
very top (and the angled part that meets the windshield). That would be
where the silicone spray would be administered.
If it's sticking in /any/ position, then the run channels on either side
are where the lube should go.
If lube is applied with no success, then start looking more deeply at the
Use whichever one you can find at your local hardware store; they're all
pretty much the same.
Industrial supply shops often stock a dry powder spray as well as the wet
spray. I'm not sure one is better than the other in your case.
I lowered the window and discovered the track you mention is on the
outside. I applied the silicone spray and operated the window up and
down through several cycles.
It is much better.
But, the motor labors about half way down (only) but gets the window
down. It elevates without any noticeable labor. What might that be?
Also, I found a DRY lubricant, PTFE-based, aerosol can. Would that be
compatible with the materials it would come into contact with for this

Possibly the part of the track that you can't get at with the spray
because it's inside the door.
Sometimes hangups like this are due to worn parts, but the passenger-
side usually gets quite a lot less wear than the driver's side, so wear
is probably unlikely.
It's possible the regulator's horizontal track is dry of lubricant, but
you can't see that unless you start taking the door apart.
I think you'll need to remove the interior door trim panel and rain-
protector sheet and visually observe the window's travel up and down.
Repeated ups-and-downs while watching carefully will either solve the
problem through lubricant distribution or reveal the source of the
hangup. Plus this will allow you to spray that part of the run channel
that's hidden inside the door.
Teflon works about as well as silicone, I've found. I forgot about PTFE,
otherwise I would have suggested that as well.
Thanks for the offer. Every bit helps. You can send contributions to the
