The window regulator failed on my 93 Nissan Sentra, probably because I
cleaned the driver's window channel (2-dr) so well that the glass bound
up and the cable failed.

I think I can install a new regulator, but what do I lube the channel
with to prevent another problem? The passenger window is almost never
used, but probably needs help too.

I'm posting this to several NGs because a.a.nissan is a really slow
group these days.

Thanks,
Jm

If you are talking about the channel in the window frame, I'd use a silicone
lubricant because the silicone doesn't cause the rubber to deteriorate more
quickly.

The channel in the door itself could be lubricated with lithium grease if it
is not lined with rubber.

You're welcome. By the way, the silicone lubricant does not last very long,
so you may have to re-apply once or twice a year. If you want something
that lasts longer but is pretty messy, you can use soap-based brake caliper
grease.

The channel that the glass slides in is not lubricated. The various channels
of the regulator itself are lubricated, but not the chanel for the glass.
This needs to be clean,

My guess is that your 1993 Sentra window regulator simply wore out.

A typical construction is that there is a stirng of balls that is pushed and
pulled through a guide and is connected to the window. As the motor pushes
and pulls the balls, the window goes up and down. The string of balls will
break over time. There are variants that involve scissor mechanism to raise
and lower the window, but these are generally found in older cars.

In any case, the glass should slide freely in a clean track.
