replacing vinyl rear window
 
I have a 2000 boxster with a vinyl rear window. I used plexus and saw tremendous improvement, however there is a small hole developing in the corner and the vinyl window will need to be replaced eventually.

Does Porsche sell a replacement vinyl window? Has anyone else successfully replaced a vinyl window? Does the entire convertible roof have to come off?

I was considering a boat repair shop since boat covers use vinyl windows all the time, but I wanted your input before I did anything.

Thanks for any input.

Many top shops are set up to replace vinyl windows. In Long Beach CA a shop does it for $350, San Diego $450. It does vary based on where you live.

Based on what I've seen I don't want my plastic window trimmed right to the edge and another sewn in on top of the leftover flange resulting in 2 rows of stiches. That's how the Long Beach/Signal Hill shop does it.

When I hear of a shop that does it like original, I'll consider the price.

My recollection is that porsche does not sell just the window.. but for about $3k they will sell you a whole new top.

GAHH makes replacement tops, but I don't think they do "just windows".

I just replaced the rear window in my BMW 323iC but it was made to zip out & back in. I haven't found a rear-window-only anywhere yet for my Boxster though. I was at a marine canvas place today asking about replacing the window (he actually has roof replacement experience as well) but he didn't give me high hopes for an easy exchange.
Right now I'm looking at replacing the entire roof with a real glass rear window; anyone have a good source? (I did look here on Pelican; maybe I missed them....) Price & quality?

auto tops direct and GAAH are both good suppliers for tops.

If your canvas in good condition and you want to reuse it, you can remove the entire top with frame and a good top specialist with Boxster top experience can sew in a new plastic window. This will be the most economical as the labor cost to remove the entire top mechanism is far less than R/R-ing the canvas from the frame.

There are several options or techniques for the actual sewing or seam work. Some installers will try to match the location of factory stitching while others will sew a new seam next to the factory stitching. There are also options on the thickness and color of the replacement plastic window panel, green tinted to match OEM, "crystal" clear or tinted.

Fortunately, I haven't needed to have this work done yet, so I have no first hand experience, but have followed several related threads on the subject as I know my top is on borrowed time.

Good luck, let us know it works out.

You should be able to call any convertible top joint where you live and get a price. I'm sure it's cheaper if you remove the top yourself and take it to them. It only takes about 1.5 hours or so to get it off. It's pretty simple with two people. The micro switch on the left side of the frame is not hard once you've done it. You move the hold in clip sideways. Instead of what you think is correct.
After taking this thing off once. It's just not hard to do.
Good luck, Randy

I do not believe Porsche replaces just the window. If you go to a dealer it will be the entire top.

Personally, if I were going to redo the top I would go with a GAHH top and get the glass rear window.

I know shops that have done it correctly, but they are in the Pasadena/SGV area. Give Tony Callas a call, I'm sure he knows of someone in his area, which is closer to you.

Porsche does not supply vinyl rear window. They replace the entire top.

I have successfully replaced my vinyl rear window with another DOT approved rear window for $300 total at a shop in Philadelphia, PA called Rydon. It was an auto and marine upholstery shop.

They did require to take the entire top off so it took them about 4 or 5 hours to do the job. I have been driving for 3 months with the new vinyl rear window and so far there are no leaks or problems and visibility is clear. It looks like new.

BUT, I still have to manually push the vinyl window down to help it fold correctly when opening the power top because it can still crack even in warm weather.

rear window
 
I'm in Atlanta and the dealer told me of a local trim shop , +/- $600 . I think Jake has a shop in North Ga who he has used for @ $400.

Vinyl Window Replacement
 
I recently replaced the Vinyl Window in my 1999 Boxster. Would have liked to put in the Glass Window but you must replace with new Top if you do. The Glass is much small and reduced view as well. Cost was my factor here. My top was in great condition and the Vinyl Window replacement only cost me $475 in So Cal. The Glass Window was $1500 to $1750. After watching the crew of two remove the top and then replace it. Not sure I would want to do the job. They really knew what they were doing. SmileWavy

You can find OEM equivalent plastic rear windows for sale on eBay. A good auto upholstery shop should be able to sew it in for you but as has been stated already it usually results in two rows of stitching and a rough edge of left over plastic, from the original, on the inside of the top. My '99 Boxster had already had it done once so the top had to be replaced. The tops start wearing out at about ten years so if yours is getting that old you might want to think about biting the bullet and replacing. I picked a new GAAH A5 with glass window up on eBay for $329 from a couple who were closing their upholstery shop in Marin, CA and were liquidating the remaining stock. It did not come with the defroster cable though so I'm still looking for a used on or I'll make one.

I just replaced the back window in my 2002 Boxster. I picked up #138 polyester thread, .40 mil clear vinyl, UV 6800, and a Speedy Stitcher awl. I wasn't going to attempt taking the top off so I sewed the window in while it was still on the car. It took me a while, and lots of holes in my fingers from the awl, but I managed to sew in a new window! I used the same holes for the stitches from the original window. I think it may have cost around $85 for everything. One thing I would do differently is cut the new window larger than the old one. I used the old window as a pattern and this was not the best route. If I can do it, anyone can.

First step is to be sure what clear vinyl the 'top shop' is using. Beware bait & switch. If you use cheap chinese clear vinyl w/o a reliable marine u.v. rating ,it is a waste of money.
Do the research and buy "Marine Grade" vinyl. Thicker is NOT better. It will be difficult to fold. Take your top to a place that does boat tops?
Google Strataglass ,Crystal Clear and similar.

plastic window
 
Check out the Prothe, Mathews, N.C. , on ebay, under Boxster Hardtops. A window kit for $79.00. My top is in fine condition, but a cracked window. Top shops in AZ claim it can't be done on the car!

I just had a GAHH top installed on my 2001 Boxster last week. I could not find anyone in Houston who could sew a new plastic window into the existing top. I do LOVE the glass rear window!

Hello, I have a 2002 S. My rear window cracked one frosty morning in the UK just about 2 years ago. I decided to replace it myself. The job was a success I posted it all on this forum with lots of photos. And yes you do need to take the roof off and start the job in your lounge. Take a look anyway.
