Part # 9666748

 

Dan:

I bought a fleet not to long ago and that was one of the problems noted with the car. Truth be told - I spend about $10 and about 2 hours fixing all four windows. Taking the door panels off wasn't too hard (easier with special tool and remember too much force can pull the tabs off the door panels). The next issue was shaving the replacement slide down to size to fit into the track [you're right either end is tappered] - but I was able to do it. I would recommend that you lubricate (at least WD40 thought silicone is the smarter way to go). Hope this was helpful

 

P.S. - the link above is EXCELLENT!

 

that's awesome. I went into the cadillac dealer with this issue a little over a year ago and they told me the only way to get the clip was to buy the entire window regulator unit which was just over $300 at the time. I guess now I can go to any gm deal and buy the clip directly. Thanks, you guys have been a lifesaver.

 

interestingly enough, the local chevy dealer had 4 in stock for $3.74 a piece. Unfortunatly rather then being stock they looked like the attached picture. They seem to actually work better, partial because it was freshly regreased but partially because they can rotate. I feel confident that these are less likly to break then the originals.

 

Wow, that's news to me too!
Too bad you guys didn't pass this on a few weeks ago, you could have saved one of my grumpiest customers quite a bit of money.
The real problem is his other window is starting to do the same thing.
Now if I call him he'll just be mad I didn't fix it this way before!

Yes, they stopped using those original-type sliders a while ago and replaced them with the rollers for obvious reasons--mainly the sliders have a few weak spots and can snap easily. The rollers don't break.

The driver's side doors of my '95 have fresh rollers, but both passenger ones are still going fine on the original sliders. It was a VERY easy fix, especially since you don't have to drill out the rivet or anything like some instructions say, you just have to bend the end of the track out a bit and tap the roller sideways (we used a screwdriver in the roller hole, then tapped the handle of the screwdriver with a hammer until it was in past the rivet and rolling free.

 

On my two '94 Fltwds, one has a left read window broken, and the other has a right rear window broken. Haven't fixed them yet, or even opened them up, but I suspect the same problem as you all describe. I just keep the window lock on at the drivers door controls.

Thanks for the offer Dan, but I would hate to commit to a price and not have the part work as well as the OE replacement.

Thanks for all the information on the window fix. One day I'll put it to good use.

 

as you can tell I didn't actually have any machined since gm had a replacement part available (gm part # 966-6748). Just order up to 3 per window and it is a pretty simple replacement. It was a little snug to push in which is a good thing and don't forget to lube it, white grease works best.
