Are they as bad in other cars GM makes? Is it just that since the F-body windows are so huge they die earlier?

 

What happens is gunk gets down in the tracks over time. The gunk causes resistance, which causes the motor to strain, heat up, and wear out. I read a post on LS1.com about a certain kind of solvent that you can squirt down there and cause the gunk to come loose, forget what its called.

 

I work in a fast food drive thou so i see people who come in and open there door cause there window is broke and most of them are GMs. I not a big ford fan but they can make a good power window....and thats about it lol

 

I think Chrysler pw are worse. My mom had her driver side window go out twice in 90k miles on her old 96 caravan.

 

lol... you see "most are GMs" because most cars ARE GM. GM "had" ~80% of the market place for several DECADES, and only recently has dropped that number to ~40%. The top three runner-ups combined don't have that kind of production history... until recently at least. Of course, you wouldn't expect a new car to have window problems at all, so maybe that's why the old GM marketshare is showing up in you sample methods.

Just a thought.

 

I have a slow mover on mine, anyone know what the name of this solvent is?

 

Gasoline.

Follow it with a match and no more window motor problems.

Think of all the things working against the window motor:

big, heavy, honkin' window in a two door car

compound curves

window does not go up in a vertical plane

frameless design that does not hold the window in place

all those darn drive-through windows!

 

I had to replace mine about a week after I got the car, that was the passenger side went out. I don't know what other power window systems look like but looking at this one it just dosn't seem it could be very reliable.

 

I believe people were using silicon spray on them to have prolong the life.

 

Gasoline.Regular or premium?Actually you can buy some time buy greesing all the tracks with all purpose greese.But when you have to replace the window motor(using Shoeboxes guide of course),then you and the car become one.Then you can do almost anything.It trully is an education.Anybody got a dictionary?My02

 

wow, what a pain I had a friend and my shop teacher helping me and it was still a pain in the butt. I was holding it, my friend was lineing up the holes and my teacher was punching in the rivits. Man nothing on these cars is easy!

 

I have doen quite a few of them in the field and for my buddies. Auto Zone has lifetime warranty motors. Shoebox's guide kicks ***.

 

Any idea how much the autozone motor goes for?

 

my family has had and still does have two luminas (92 and 96) and neither of them have had any of the window motors replaced while my 97 needs a passenger side motor pretty bad

if i had realized the motor was bad i would have been able to get the previous owner to fix it before he sold it to me...along with my cruise control that doesnt work that i didnt know about...i shoulda checked

 

My 74 Caddy still has all 4 original, working, power window motors. So no, it's not a regular problem with GM cars. But for this car, it's one of the more unreliable parts, just because of the design...
