Windshield molding

The upper molding on my windshield has been cracked for some time. Now pieces are starting to break off. Is this something that a auto glass co. can replace or do I have to get a new molding from a parts source?

I'm getting ready to replace all of them around my windshield. My understanding is that many places will tell you the windshield must be removed, but this isn't true. The parts are cheap and its an easy DIY. I plan to do the lower windshield cowl at the same time. That's about $120 whereas the top piece is closer to $30.

Mine did the same thing on my 2004 Z4 . I replaced mine myself. All you got to do is pull out on it gently and it will peel right off. I purchased my new one from my BMW dealer parts desk. Line the new one up with the groove than just press it right in. Very easy fix.

Don't pay to get this done. Far too easy to do for anyone to give money away to another person.

This will take you less than 10 minutes.
Make sure it is inserted all the way...if it's raised from the windshield it will make noise from the wind. You might not notice it till you drop the top down.

My girlfriend has a 2006 330i - the glass company told her it would be over 270 because they needed to remove the windshield....

I am not mechanically inclined at all and installed the trim in about 20 minutes. Like someone said a glass installer had told me the windshield would have to be removed. Again thanks to this forum that saved me a bundle. Do not be afraid to do it yourself because it is a piece of cake to do.

Any tools needed?

None. Just the palm of your hand and a little window cleaner.

A plastic putty knife will be helpful.

Windshield molding

The upper molding (Mfg Part# 251-31-7-017-021) on my windshield had been cracked for some time and pieces started to break off. Also the cowl (bottom of windshield) (Mfg Part# 151-71-7-017-022) started to crack. Replacing the cowl was the hardest part.

The molding was easy, just pull out the old one, starting at the corner and finding a section that doesn't crumble and push in the new one. I don't what the trick is to keep the new one from popping back out at the passenger side.

The challenge for the cowl started with removing the wiper arms. Here is a well done thread (for 3 series, same idea): http://www.e90post.com/forums/showthread.php?t=459978 The mount is conical, there is a taper on the shaft that matches the inside of the wiper arm. I am glad I had a small universal gear puller for that task.
Note the location of the wipers before you remove them. Place a piece of tape on the glass where the wiper rests and then make sure to return it to the same spot.
Where the cowl is mounted to the firewall are four mounts. Don't remove the plastic screws all the way. (I did and it was difficult to remove the grommets, lost one when popping it out). With the plastic screw one turn left in, pull out the screw along with the grommet.

The damage was $64.10 for the molding and $149.72 for the cowl, guess prices have gone up - or is it Florida?
