I have an '86 coupe that I have been slowly renewing. Last year did carpet and weather stripping. The weather stripping was real tight, had to open door to close window. Thought it would smash down a little and be okay, but it didn't. It gets about 3/4 of the way up and slows way down. Can help it from the inside or open door to close the rest of the way. Is there a way to adjust the window so it tilts out just a little more as it approaches the top? Any input would be greatly appreciated.

 

Had the same problem.....
roll the windows up close the doors and and let it sit in the sun as much as you can. I ended up having to shave off some of the seal about 12" up from the lower window(drivers side) seal. if you watch you will see it draging. after you trim it heat up a putty knife and smooth out the seal. It seams to be working for me.
I used an after market seal kit, guess thats what it get for that.

Good luck

 

I have not yet shaved any stipping but I feel your pain. I left the top on and the windows up ALL winter hoping the new stripping (both halos and the top) would settle in. I took the top off a couple of weeks ago then put it back on Friday to wash the car for a parade...same ol' BS. I have to sit on the rocker well and PULL down on the top just to get the bolts started. Sometimes the passenger window won't go all the way up. Learned my lesson (again!)....always do what the manual says, run the fluid the manual calls for, and only use GM parts for replacement!!!!!!!!!!!!!

 

I replaced the windshield and targa weatherstrips last Fall with US-made repros (not sure of the actual brand name). Initial fit wasn't bad but I ended up adjusting the side glass anyway. The end result was great. I didn't think the original glass alignment was perfectly 'square' with the frame to begin with though it did mesh well with the original weatherstrip. There is an adjustable bracket at the upper/outer edge of the door that seems to have some effect on the tilt of the glass near the top of its travel and also limits the travel of the rear part of the glass. It took a LOT of time fiddling with these and window regulator adjustments to get it right. Finally dragged a dollar bill to check for how much the glass squeezes into the weatherstrip all around.

One thing about the '86 is that it was a transition year away from the old style ribbon regulators. Some may have had them on both sides and many (mine included) had the new style on the driver side and the old style on the passenger side. I found the old style slow and weak compared to the new one and upgraded. (I rapped my glass with a ratchet during the regulator upgrade and how I learned about about glass replacement and adjustment. ) The ribbon regulator may lack some muscle when having to deal with new weatherstrip. Silicone grease might also help.

 

I have heard that Rain-Xing the window will help it slide on new weatherstripping.

 

I have not heard of that before. I supposed it could have hapened, but more likely, someone replaced an old style regulator when it packed it in with a new style one and never got around to doint the other side. b
I had the same problem with the slow windows and cured it by replacing the regulators with new styles.
As far as the targa roof goes, that can also be adjusted. Simply take the plastic trim off, (the sun visors and rear view mirror will have to come off for that) then put the targa roof on after loosening the two torx bolts on either side and mount the roof. Once it is on, tighten the two torx bolts. The targa should now line up and go on way better.
Worked for me.
