Knowing that all 928 owners are rich, someone smashed my passenger side window and foraged for things to steal. Great video. He left empty handed. I have removed the door panel and got replacement glass off of EBay.

I am assuming that the glass needs to be put in from the top and from there slid in to the carrier. Assuming I am right, does all the molding around the window first need to be removed? If so, can anyone direct me to a "how to" site? I am trying to get away from my standard "just tear it apart" propensity and approach this in the correct step-by-step manner.

Thanks in advance.

remove the door panel, remove the inside rubber molding thats under the door panel. ( this runs along the inner side of the window)
Remove the 2 felt guide pads . Then you can slide the new window into the door. With the felt pads out you can inspect them if the felt is worn then glue on new felt, if they are dirty scrub them with a dry tooth brush .
You may also have to remove the center tube that runs from top to bottom , but try installing the new window without doing this first
None of the outer rubbers or moldings need to be removed

Thanks. I see the guides. Should the window then just slide in straight, do I have to tilt it, ...? I can't seem to get it to "fit" in.

Mrmerlin

there is a rubber strip that runs along the inside edge of the window opening remove it then remove the 2 felt pads the window will slide in once the felt pads are removed

Thanks! One last question since I still can't seem to get the damn thing installed. The glass itself sits it a carrier that attaches to the glass. The shop manual picture, poor that it may be, seems to show this attached to the glass before the glass is "slid" in. Not going to happen even with the rubber strip off. With your suggestion, should I expect to be able to get the glass into the carrier without having to mount the carrier to the glass first? Having tried that once it will be a real pain but I see no alternative.

Is ANYTHING on these cars easy????

Thanks again.

Ah you may have to remove the bolts that hold the window regulator in position, to that first remove the wires from the motor then 4 bolts 10mm heads then let this part rest in the door then install the window and use tape to hold it in place up position. Then slide the window arm into the window track and the refit the motor. Then let the window down and install the felt pads, put the window up and see if the felts are both in a good position tighten them then install the rubber window felt strip test the window again then lube the roller and the inside door latch then fit the plastic sheet then the door panel

I hate those felt wraped retainers. Seems like an Uber engineered Porsche would at least have little rollers on this part. I've had two sharks (my current one included) that have had scratched interior sides from the worn away felt. I've got new glass for driver and passenger waiting for instal, but I'm going to wait until the mechanicals are all corrected before I start on the beauty items. I swear I will come up with something better than that cheap felt.... I know someone recommended Dr. Sholes moleskin? or something along those lines to replace the felt with. Post some photos of your replacement job if possible. It could really help me as I am going to be doing this same operation really soon.

Good Luck!

Mrmerlin and Mike:

Well, I got it in but ended up attaching the carrier to the mount on the guide tube and then slid the glass into the slot on the carrier. Removed the rubber from the carrier itself as it was the only way I could get the glass to go in. Sorry, Mike, but I had it in before I got your post re pictures. Not too sure they would have helped anyway as there is so little room to do ANYTHING in these doors that I doubt I could have made any good, or helpful, pics. Removing the felt guides and the inside rubber trim seems to be a must to get you the room you need to slide the new glass in.

I would LOVE to see how the "experts" (like the guy shown in the shop manual) get these things done. They must have smaller hands and much more patience than I do. I'm still working on replacing the latch mechanism in the driver's door which has been out for several months. Don't get me started.

Anyway, thanks MM and shoot me an email, Mike, if I can help shed any light on this repair. patrickpbme@yahoo.com

A little help please.

Does the window come out toward the inside of the car?

I've got it almost all the way out, but it seems just a couple more inches.

I hate working with glass.

BTW, this started because of the horrible rattling due to the insert at the bottom of the rod going.

Of course, the fastening plugs (928 537 281 04) are broken.

WSM shows the door glass coming out of the door toward the outside of the car.

I couldn't find it in the WSM.

But I got it out toward the inside of the car.

Mrmerlin

do you mean that the center guide tube has failed at its lower attach point?
So you need a new center guide tube?

LT Texan

The rubber grommet at the bottom of the guide tube failed and I get a hell of a racket from the tube banging against the pin.

The plastic things that hold the nuts on the back of the window have cracked all to hell. The top guide attaches to this.
