I just replaced the pillar and t-top weather stripping on my 95 corvette. I've been trying to align the window, but seem to be getting no where. Is there a way to adjust the front of the window down, or in more. I can adjust the back, just the front doesn't seem to have an adjustment. The way the weather stripping sits with the window currently, I can't shut the door easily. Nor does it seal at all.

Here are some pictures:

 

My son and I had the same issues with my 95.

The previous owner replaced the factory latex with rubber. It is not the best quality and my drivers side had the same issues. The passenger side less. The previous owner gave up. Used adhesive type foam expanding insulation in the area in your picture. They couldn’t get the targa top back on because he also replaced the targa top weatherstripping and b pillar weatherstripping.

Back to your question. We had to adjust the glass. There are a couple of YouTube videos and a couple of nice write ups here by people much more knowledgeable.

A quick summary of what seems to work for me.

Connect a battery charger to the car.
Use some silicone grease on the weather stripping to make it easier for the glass to slide.

Remove the door panel. It is easy. The push pins at bottom of door pop out. The are screws by the door pull and under the door courtesy light. You have to pop the sliding lock mechanism out and there is a screw underneath.

At the back of door, there is a bolt with a nut. The bolt has a hex fitting in the center. It will be visible once the panel is off. If you look at the assembly while you move the window up and down it will be clear how the assembly tilts the glass and stops the up ward movement.

We had to adjust the glass in the regulator first then adjust the tilt.

There are 3 attachments for the glass. One in the front of the regulator and 2 on back. The glass has to be almost to the top to access them. The front attachment only allows forward and back. The back 2 allow up and down.

For us the easiest way to adjust was sit in the car with the window controller connected. Close the door to the first catch with the window half way down. Then slowly raise it to the point you can access the 3 bolts. Loosen all 3. Slide the window forward so the window is contacting the front weather strip. Then adjust the rear height of the window so the glass at the rear is 1/4 inch higher or parallel with the top targa top weather strip when compared to the front. Tighten all three bolts. Then raise the glass all the way to check for fit. It is much easier to move the glass if I stayed in the car with the door latched and my son on the outside. We could both slide the glass with smaller movement and less strain.

Once it fit well, we made sure the door would close.

We adjusted the tilt at this point to keep the glass tucked under the targa weather stripping.

We did this several times until we were happy with the fit in the front. The rear had small gaps. 1 inch long by less than 1/8 inch. For it I took 5/32 vacuum tube under it to lift it slightly.

Good luck.

 

Thank you for all the information. I have taken off the door panel. So far only the drives side, but it appears the front bump stop for the window is slightly damaged, because of this the front of the window wont stay down far enough. So I am going to order one for each side. Hopefully this helps that problem, but I will need to adjust that window a lot afterwards. I've heard many people say to put silicone grease on everything, I didn't know that helps the weather stripping wish I knew that a car ago lol.

 

Our forward stop was broken as well. When it was replaced, there was no effect on the front windshield stop. With the door fully closed the window stops due to hitting the top of the weather stripping. Even at its lowest setting it barely contacts the stop. We set the stop at its lowest position to prevent the window to go too high if raised while the door was open. But with the door closed it was the weather stripping that stopped the window.

That may all be due to our rubber weather stripping. I have no idea where it came from.

A slight rear elevation of the glass in relationship with the front made the rear weather stripping slow the lifting then the glass sealed back to front with the weather stripping. The front portion of the glass contacts the top weather stripping last. I hope that makes sense.

We drove ours this afternoon and except for the wind noise no leaks!

What brand of weather strip are you using?

 

Sorry I was waiting on those window stop alignment... things.. to arrive. I got the one installed and it is helping, I didn't realize how bad the one I had was. The weather stripping I purchased was off ebay, no particular brand. But it does seem to be of decent quality. Except for a couple of spots that protrude out and hit the glass first. I'm not sure if I should just try to shave them down. One big spot is where the top connects to the b-pillar and the weather-stripping from the top hits the glass before the rest and doesn't allow any seal from basically all of the tops weather-stripping. Its not much but when everything has to be pushed together to make a seal it wont work. Another spot is where is right along the a pillar inside the door jam, makes the door hard to shut and will bounce the door back even with the glass inside the door. I really don't want to buy another weather-stripping kit, because I fear the same thing will happen.

 

Both of our doors latch at the first catch easy. They do make contact at lower A pillar first. Before we adjusted the windows, the driver door was difficult or impossible to close. The doors take more force to close with the window up, but both close easily with a constant pull. No rattles in the glass. With her buttoned up and AC fan blowing, we stood outside the car. When we run our hand along the window, drivers side really minimally leak at lower rear glass where door meets the b pillar. Passenger minimal leak at front of glass mid way up. But I don’t think we are going to worry about it now.

To get an idea of how small these leaks are, both corners of the rear hatch weather strip are torn and gone. The air leaks at those locations was much greater. The air coming out had the same force as the setting we selected on the blower at the main center vent in the car.

The targa top weather strip in the front and back is firm rubber and must be completely seated. If it protrudes, the glass will be pushed away from the pillar.

We coated both ends of the targa weather stripping with silicone spray and slid them in to the groove. Once the ends were in place then the center portion was popped in. The strip seated much better and didn’t push the window out.

Adjust the glass in the regulator. The last adjustment was the tilt. About 35 degrees inward tilt on both sides worked well. Finally, we used the vacuum tubing to shim any leaks.

 

When you say adjust glass in regulator, do you mean the two nuts that hold the glass in towards the back? I've been adjusting that, I feel like I'm not quite getting what I want accomplished. The problem I'm now having is the front portion of the window doesn't tilt inwards enough, where as the rear portion tilts too much. I plan to bring this car on Hot Rod Power tour, so I might just have to bring it to someone since I'm struggling to figure this out.

 

I figured it out!! Fighting myself this whole time. So to anyone who has a similar problem. The solution is just to slide the window back, using the 3 window bolting bolts. Don't worry about tilt as much as I did.

 

How did you attach the vacuum timing to fix the leaks? Under the weather-stripping? Connected to the window? Or just glued to the weather stripping.. if so what glue did you use.

 

Glad you got it. I agree the tilt is not the important adjustment. When you look at the glass it does seem that would be the issue, but the window tilts on its own. The important adjustment is the glass in the regulator itself. The forward and aft position seems critical. Then a slight elevation of the back portion of the glass so it contacts the rear targa top weather strip first.

Our air leaks were at the rear of the glass on the b pillar. We were able to lift the weather stripping away from the plastic interior trim and wedge a small section of vacuum hose in the space to lift the b pillar weather stripping slightly. The main portion stayed in its groove. This sealed it well.

 

I have moved on to the passenger side now. I'm starting to realize there may be no way the bottom of the window can seal into the a pillar properly. The door weather stripping prevents it (look at picture). But the other problem is I've run out of adjustment. I cant put the window any further back to fix the problem like I did on the driver side. It is maxed out for the 3 bolts that hold the window in. On the other side if I did this the window would touch the b pillar. But the passenger side wont even get close. I'm thinking of bringing it somewhere to fix it, since it has been a major headache.

 

Try to tilt the glass in the regulator so the rear of the glass is more elevated. The front will not contact the weather stripping until the glass is completely raised.

The real problem is the cheaper rubber weather stripping.

You almost have it. Don’t give up.

 

I looked at again. This might be an area where you could place some vacuum tubing under to lift it too.

 

The rear of the glass is elevated as high as it can go and pushed as far back. The front adjustment is all the way down.

I wish I bought the better weather stripping now.

I'm not sure I understand what you mean here. I believe you mean to push the a-pillar weather-stripping towards the window. Just correct me if I'm wrong.

I appreciate the help a lot.

 

Hang in there.

Star over. Close the door to first latch. Center the window in opening with the window level as compared to the targa top weather strip. Do it seated in the car.

Latch the door fully and raise it fully. See where you stand.

You are correct. You can lift the weather stripping slightly from the trim and put vacuum tubing under to lift it some.

 

I had gotten the weatherstripping best I could for what it’s worth. But the $140 eBay weatherstripping is trash. I do want to fix it right though. What’s a good weatherstripping kit someone has used. I don’t want to waste my money on that junk again. If I have to spend $500 that sucks, but I’ll do it.

 

After living with my cheap weather stripping on the doors. I bought Corvette Rubber Company. Night and day better. Better seal. Easier to close doors. Targa top goes on so much easier.

Money well spent.

 

New weather stripping from corvette rubber company. So much better of a weather-stripping, doors shut easily, way less wind noise while driving. Along with the weather-stripping aligns with the window better. I can now comfortably drive 75 mph without a annoyingly loud wind noise. One thing holding me back is the plastic front window guides/stops. After already replacing each one on both sides, they broke again. They are cheaply made of 1/16 in plastic. So I decided enough is enough and I have 3d modeled and am currently printing a thicker (1/8 in) model of the guide/stop, along with filling some areas that can improve the strength of them. I'll post again later with the file for each side, but I'm gonna test them out first and see if they work good.

 

I think that’s awesome. I thought about doing the same, but mine were so shattered I couldn’t see how they looked originally. Are you using nylon or PTEG?

I agree the Corvette Rubber company is great! No window adjustment needed with it. I got caught in a thunderstorm no leaks front or back after it was installed.
