There is some info on adjustments in our tech article here: Porsche 911 Window Regulator and Motor Replacement | Pelican Parts DIY Maintenance Article. Also look at the comments/suggestions section below the article itself for additional info. Hope that helps.

The Bentley Manual has instructions.

It does take a while.

pm me as needed.

Best,

Short summary before you go to your Bentley- remove the door cards, loosen the adjusting nut, put the window all the way up, tighten the nut, repeatedly run the window up and down to ensure you got it.

Repeat in two years.

The main trick is the front windshield targa top seal, if proper OEM style then the windows need to be align accordingly. If OEM 964 superceded one it will not fit properly and cause the top to sit too high and not properly align the windows. Also if PO or body shop messed with the inward angle, you will need to adjust that as well.

OP, Post pics of all angles and it will be show us the state of the window alignment. One more thing make sure the "L" bracket is not broken, that part is the weakest part of the window on a targa and cab, especially if one uses the window to close the door when they should be using the the door handle or door itself.

This is exactly my problem,window is adjusted with the heights problem is that when i close the door glass does not go inside of the rubber seal,it always seats on the top and i have to push the glass in so it slides inside of the seal.Seals are OEM,i did a targa top 6 months ago and I kept seals.
I have two photos they are not the best,it was raining today so I couldnt do nothing better,ill try tomorrow to make better

Yes I have this problem too. Anyone have it documented how to fix?

A couple of observations: (1) the window is going up too far relative to the rubber window stop, this is adjusted via the motor stop adjustment; the alternative is that the vent window frame is too low, which this is adjusted via a set of bolts that hold the frame in place. To see if the frame needs adjusting see if you have a good firm seal along the A pillar and vent window frame, as well as the space between the top seal and top of the vent frame. To test these gaps try pulling a test strip of paper through both of these spots, and if the paper doesn't tear you need to raise the frame a tad. Don't overdue it or else you won't be able to close the door (2) the top of the window doesn't fit into the rubber roof lateral seal. This can be adjusted by either slanting the entire window frame and window inwards, or by adjusting the rubber roof lateral seals by loosening the screws holding it in place and shifting outwards. I would suggest moving the lateral seal first to see if that addresses the fit.

What about the fit at the upper rear edge of the window, as well as the fit on the rear vertical seal. You haven't posted a photo of that area, so it might be a factor that will impact the rest of the window fits towards the front.

Frame is def too low and going to leak if you can see those screws with the door closed. Need to raise it. Frame could be out a bit too far at its top also, but seal on A pillar looks tight to me. So you could be well served by moving top's side seal out first ... easy to try. A dollar bill makes a good test paper for both A pillar and top-to-glass testing.

Once frame and top side seal connection is dialed in, then work on glass and rear of glass align, otherwise you'll be chasing your tail.

I have some new photos

Based on the photo showing the complete window, it looks like the top seal looks to be angled, since the rear upper corner seems to fit under the seal as it should, while the front upper section of the window runs on the outside the seal. Loosen the 4 screws on the underside of the lateral upper seal, and move the front half of the seal outwards, re-tighten and check to see if the window slides into the rubber channel along the entire length of the window, and that very little if any of the screws on top of the vent window frame are showing.

One note, the vertical seal on the rear targa bar appears to sit a little low (the ideal is to have a tight fit between the top lateral seal, and the ridge along the vertical seal). Does the vertical seal fit tight against the glass?

David

^^^ good advice

you'll get leaks into the cabin where the bar seal hits the top seal (the "ridge" area dyerkes described) if this car gets wet.

And the frames are too low also. Your L-brackets (rubber catch for the window on the vent frame) have split due to overuse/hardening/the window being raised too high over they years. Not an easy fix but if you want to do it right, you should R/R those too...

It's a slippery slope when you start tweaking a targa top...

My other problem is that the plastic in door stricker is broken and doors are kind a loose,they can't be closed all the way.i ordered from pelican today plastic for strikers so I'll try that first and after that I'll start with adjustments

[DRACO A5OG]

Thanks for the pics Sleeper.

Okay first thing, note the front part of your top's edge, that actually should be sitting into the windshield groove. The reason for this would be the seal is sitting too high, as a result, you have a gap on top of the quarter window.

When it stops raining, please show pics of the front seal. Unfortunately, this means the window will need to be adjusted down and angled in. Then finally the parallelism will need adjustment along with the window height stop adjustment.

[universeman]

Dial in the doors and the top before you start messing with the glass, there's no point otherwise. Get that top as low as you can get it, per DRACO - keep messing with the front seal if you need to

[gazzerr]

Here is mine for comparison. Seems like a common problem. I think my window just comes up too high.

[DRACO A5OG]

^^^ oh yeah, you need to adjust the stop height and angle her in.

Hello There:

I have had this problem a long time ago, with my Targa, and it appears that you may need a new Targa Vent Window Cap. (It looks like yours is broken, cracked or split from the pictures shown.)

Wayne sells these parts.

Hope this helps. Good luck.

This is how you want the front part of the top to sit inside the windshield groove, any other way you will have a leak and windows will not be properly adjusted.
