WTB - I need the door glass guide (C4)

[QB93Z]

I need the door glass guide for passenger side glass.

This guide (a plastic piece) attaches to the lower, forward corner of the glass and rides on the guide bar to position the glass properly as it is raised.

My guide is broken and the glass goes too far up and then the upper rear corner of the glass hits the edge of the halo when the door is closed.

I believe that the part I need is not year specific, and it is not ZR-1 only.

Anybody got one?

Jim,

Found the the guide on ebay.

Thanks Phil. I thought it was too obscure a part for eBay. Silly me.

Bought it!!

Jim, I just did this repair as well. You're going to have fun with the nut that holds that stop/guide on. The back side is basically a big washer with 2 opposing holes and you have to either buy the tool ($65) or improvise. I used a set of 90 degree needle nose pliers. It is very tight and has thread locker on it. That was the most difficult part of the install. The only difficult part actually.

[GOLDCYLON]

Does anybody know if these will work on a 90 or 91? I know it was an improvement for all MY92s and up because of the rattle glass problems in 90and 91 when the windows are down. Anybody has this mod or done this yet? I dont think so im not sure if the 90s and 91s have the rod guide that holds this stop in the window, nor the hole in the window where the guide stop goes? Phil ??/ Anybody please advise -=JEFF=- ?

Note to JIM I think I have this specific socket with the two tines on it. LMK if you like to borrow it? Also Jim great pics below of the work details.

The parts are still available at the dealer and if you've a relationship with a dealer you should be able to buy them competitively priced.

The parts were added in MY '93 I believe and the glass was updated at the same time. These would not work in '90 cars as the glass isn't the same as later cars. "91 & '92 if the glass is original I don't believe the hole is present unless the glass has been replaced and then it's likely.

The parts mentioned are '93 thru end of production.

Note to JIM I think I have this specific socket with the two tines on it. LMK if you like to borrow it?

That is a 'spanner' socket and if yours has the round projections that are direct fit to the spanner nut that would be fine but *I don't believe the guide uses the spanner nut. The 'spanner' socket is generally pretty easily manufactured using the appropriate old socket and a grinder/dremel to modify it.

* I found a couple references to the 'spanner' so it's likely used. I've never had a later door apart.

[GOLDCYLON]

I believe it uses a spanner nut as can be seen in the mirror in the corvette forum link I provided in my post. Good info thanks.

Has anybody done this conversion yet with an earlier model car? GC

[WVZR-1]

I see a couple revisions on the glass BUT they're all 4 hole glass so if a person had the guide channels and the stops I would think they could be maybe added to the '91 or 92. I can't find any visual images of the '91+ door glass. I can find many for the '84 - '90 and again it's a 4 hole glass but is the forward most hole in the same location? If it were then the add to a '90 could be possible but you need to be able to cannibalize '93+ doors for the guide channels. There are left and right with no availability from GM.

If someone has a '93+ door on the ground they could remove the glass and I believe comparisons by snapshots might answer the question: Can these be added?

[GOLDCYLON]

Jim here is a picture of the tool. Which basically is a special socket. Lmk GC

Jim - If the tool is available I would def use it. It can be done without it but that spanner nut is so tight with the thread lock it can be very frustrating. Just my .02 worth...

GC, if I decide to do my passenger side while it's fresh in my mind do you mind a quick loan of the socket?

No problem lmk

I messaged Dan (Y-ME) and he mentions having likely a '94 glass as well as an earlier than '90 glass so he's going to lay them one on another and compare the holes. I read that the holes were changed many years ago but I'm not so sure, he can confirm. '90 and earlier glass is SoftRay, '91 is EZKool and it would be interesting to know what the '93+ door glass were. Were there actually changes physically to the glass or just the tint and maybe the sourcing. Anyone with a '94 or '95 want to confirm the branding on the door glass 'bug'?

If the glass matches then if a person cannibalized some '93+ doors for the guides then all years could be updated.

Funny I checked this thread out tonight, as we had the ZR-1 out for dinner earlier, and I noticed the exact thing that is mentioned here is happening to my RS door glass, leaving a mark on the halo.......now I know how to correct the problem.....great info.....:dancing

[QB93Z]

Thanks for all the great info guys. I am in Florida (ZR-1 Road Trip) right now so I won't be doing this repair for a couple of weeks.

Note: The YellowZ has the mark on the halo on the drivers side also, but I never knew what caused it until now. A previous owner must have repaired the glass guide.

Did the RS today, and it was going real well, but the bolt removal KMA. Ended up using a snap ring 90* pliers to fit on the other side of the glass, as there are two small holes on that large "washer". I know some of this has been mentioned earlier, here are some pics. Also removed the "cover, plate" from the door to have more room to work. Took way longer than expected, but the job is done, and the window works great. Broken piece was in the bottom of the door, I just don't understand how these parts break like they do......:confused:
Next up, LS which should be much easier to install......:-D

No problem, glad they can help you out.....
On a side note, there are 5 plastic push tabs at the bottom of the door panel. I used a tool that had a screw driver handle with a "U" at the end which worked great in removing those tabs. I found the best way was to use the tool between the top of the tab and the outside of the door panel, rather than using the tool in back of the door panel. May be common knowledge to some, but thought I would post the procedure, as these tabs can break very easily. I did not break any, as they popped right out. I am sure that the plastic trim tools would work just as well.....

Yes for the '94 &'95 cars there are 'colored' retainers across the bottom but the earlier cars are screws across the bottom.

Thanks for that info, didn't know when the change was made. Those retainers are expensive for a small part. I ordered one for a spare and will try to match it up with the ones that Home Depot or Lowes offers in their automotive section.

[-=Jeff=-]

GC,

you would also need the guide rod for the 90-91 if it is even feasible. I have my windows pretty solid without them and have one very minor leak in rain.. I am quite happy with the how the windows turned out for fitting on my car.

Great pics, However what are the attachment points (Top and Bottom) of this plastic rod?

[-=Jeff=-]

GC.. I am guessing a different hole int he bottom that might be there on our cars

But the top is the left most bolt head you see in this pic..
http://i127.photobucket.com/albums/p138/SSROADSTER/94%20ZR-1/20140810_113010.jpg

Not sure there is an advantage to adding these to older cars though

[Roadster]

Thanks......I did not even pay attention to the rod attachments, other than that the bottom of the rod is attached to the bottom of the door. I don't even know how:redface: I didn't realize that the earlier models did not have the rod or the guide???
If I get back into the door panel before anyone else does, will let you know....

[-=Jeff=-]

Tom,
my guess is a 3rd bolt head along the bottom of the door.. the other 2 are the window regulator.. when you get a chance run you hand along the bottom and check.. I am 99% sure I pegged the top bolt based on your pictures

Jeff,
I am sure you got the top bolt correct, and did run my hand along the bottom to get the old guide out, and felt the rod bottom, but did not even think about the attachment....hopefully I'll get the driver's side checked out soon, and will check.
I still don't understand how that part took so much abuse!!!

PS....on a side note, I was amazed how how good the inside of the door looked for the age and considering the number of owners this vehicle has had and its history...

[Fully Vetted]

We should all pitch in and buy that freakin' socket ($60) and just pass it around as we all need it. It really is tough to do without it. Possible to do but I bet I spent at least an hour just on that.

David, I hear you on that. ...but if you reread my post, the snap ring pliers worked within minutes to remove that bolt compared to the hour or so that I also spent trying to remove that bolt. And your idea of buying that freakin socket is a great idea. ....

[Fully Vetted]

Like I said in my previous post, I ended up using a small set of 90 degree needle nose pliers. I was afraid I was going to break the tips off of my snap ring pliers so I switched to the needle nose.

The Club should buy all of these special tools and loan them out for a PP deposit equaling the cost of replacement plus $10. I would've gladly paid $10 to borrow that socket.

Yes, did see that on page 1, I guess we were lucky as the snap ring pliers worked great for us. What a design????? It would have been better if they just put a nut on the other side.....

Good idea on the loan program, that way everyone would use the correct tool for the job.....

[GOLDCYLON]

Design? Try the heater core. It was part number 1 for the c4 and then they built the rest of the car around it. GC

I have, but that was on the 82 and the dash was completely out, which made it a breeze. I know, sometimes these are not the most fun vehicles to work on....
