I have a 2002 clk 320 convertible. The windows have started to squeal as I put the windows up or down. I'm assuming it's because of the aged rubber trim which also is starting to get caught on the edge of the window when I put the window up. After an attempt to repair the slightly torn rubber, I'm sure it's just a matter of time before the whole rubber trim just gets caught and shreds as I roll up the window. Is there a simple treatment to soften or grease the rubber to preserve it and to prevent the annoying squeal?

got a 02 430 cab, the windows sqeel when going down only, really bad when half way! never looked into it though

it happens when the rubber is dirty. clean it and use a rubber lubricant in a small cloth. you could use WD-40. a small amount will do the trick.

No, No, No

Sorry, jalberto, but you should NOT use WD 40 on rubber, as it will chemically react with it and promote its disintegration. Use spray silicone instead, which will not damage the rubber.

Thank you neodoc. I really appreciate your help. I will get the silicon spray tomorrow.
