Three cars now. Two Pontiac and one Olds. From 1995 thru 1999.
Three for three. The right rear door window.
Goes intermittent. It will go out for a few days, then work again.
One Pontiac it only did it once or twice in a year, then the car was
totaled. The other Pontiac has only done it once. But the 99 Olds
Intrigue did it intermittently a lot till it finally failed solid. Then it
and the window dropped about 2 inches. I haven't taken the door
apart yet, but eventually I'll get to it. (My daughter has it at college
Anyway, it seems weird that it's three for three on the right rear.
All but the driver window motor is original on my 91 Bonneville. The
driver door window motor was replaced in 1999.
All the windows are opened up when I drive, A/C busted.

That's odd, generally it is the other less used windows that fail.
Corrosion occurs in the motors and in the switches. When used arcing occurs
leading to premature failures.
That is why we collectors are sure to run all of the switches and motors
once a month. The windows are my old cars work fine as a result ;)
I had three of four rear window regulators fail in a four month period. The
are never opened and when they finally were (accidentally hit the buttons)
the cable came off the pulleys. I'm thinking of disabling the rear windows
on my new car for that reason.
It certainly did; that's why I posted it as a warning to others to exercise
those windows. Crappy system that would cost pennies more per car to
improve. Not just GM, they all use junk regulators from what I've seen.
Since the car buyer can't see them, no reason to use more than the bare
minimum to get by for a few years.
One must admit not everybody maintains their vehicles as needed, it must be
something are doing wrong. My old cars are not GM products but one of my
collector friends owns a half dozen GM cars from or the seventies. He does
not have a problem with his "junk regulators" from what I've seen. They
have been working fine for over thirty years. ;)
How do you "maintain" a regulator? Disassemble the door panel every 3
months or 3000 miles? I've never seen anything in a service manual on doing
that, maybe my page was missing.
Those regulators from the '70s are probably much more robust than the
minimalist parts used today. I never had a problem with any regulator in
any car I've owned in the past.
I never had a problem with any regulator on any car I've owned either,
including those today.
Everything on ones vehicle should be inspected and maintained on occasion,
if you intend to keep it longer than the three to four years, with 45K to 60
on the clock, at which the average new car buyer in the US replaces their
Unlike the cars back in the day, that were lucky to last much past 100K, any
new car today from any manufacture will easily last to 250K or more if given
the proper preventive
maintenance. 100K warranties are not unusual today compared to the 100K
thirty day warranties of old
When I owned my fleet business we removed door panels annually to inspect,
clean connections and lubricate internal parts etc.. Fleet vehicles,
unlike rental car vehicles, are generally kept in service for five years or
300K because of federal corporate tax deprecation laws.
Collectors do extensive maintance as well because they do not generally
expect to get rid of their vehicle. They generally stick to OEM parts when
possible and stay away from the rebuilt and after market stuff.
That's a pretty foolish statement Mike. For one - how often does he even
roll a window up or down? For another, it's an entirely different
regulator. The regulators in use today suck. It's a pretty widespread
You certainly are entitle to your own opinion but you can't prove it by me.
I've seen thousands of fleet cars with hundred of thousands of miles on the
clock that did not have high rates of "regulator" problems
You are entitled to you own opinion but our experience shows the longevity
of a vehicle and its components has more to do with proper preventive
maintenance than anything else. ;)
