1999 Cab triangular windows

Recommended Posts

I have a 1999 996 C4 Cab. The rubber part of the triangular windows has worn out to the point that it has gray fuzzies on it. Loren or anyone else who might know, can I do anything to make these 2 windows look like new or should I just replace them? If they should be replaced, could you please provide me with the part numbers? Thanks.

I don't think you want the glass and gasket - just the gasket (item 2) right?

996 543 615 03 Left Gasket

The service manual says you need to remove the side window to replace this piece - but I wonder if it can be done with the window fully raised. Send me a PM if you want the window removal instructions.

To replace the seal:

1. Remove adhesive residues from above and below the window profile if present. Pull the side window seal from below into the window profile. Pull it in using soapy water as a lubricant.

2. Clean the upper seal end (free from grease and lubricant). Coat the upper surface of the seal with Loctite 480 instant adhesive, and bond with the profile of the side window.

Do we know how it went ?

I am looking at the same problem. The seal item 2 needed top be replaced. Has someone ever tried this ? and does the window need to come off just for changing the seal ?

Even my local dealer did not look to happy when I asked for a fixed price on the job <_<

Thanks for any imput,
