Repair of the A Pillar Molding to stop the common ?rattle/wind noise? complaint.

[Easy Ed]

Brought over from other site for future questions.

At 46,385 miles the repair is needed again on the passenger side because I had been hearing the noise again for the last few weeks or so now.

The truck had both sides repaired at the dealership with 30,410 miles on the odometer using this same method. I am hoping this time it will last longer, if not the next time I?ll just turn the radio up louder when the wind is above twenty mph.

Picture one is the removal of the ?Non Functional Air Intake? and done by pulling straight up on it to release the four clips in picture two. Mine come off easier than I thought it would and went flying across the hood so don?t be surprised if yours does too.

Picture three shows releasing the doors rubber molding from the A pillar molding by pulling towards the front of the truck.

Picture four is of the doors rubber molding being removed from the A pillar molding.

Picture five shows the removal of the two Phillips head screws from the A pillar molding. Once the screws are removed you will need to pull down and out (and also release any possible 3M tape that may still be sticking to the windshield) to remove the A pillar.

Picture six shows the existing 3M tape on the inside edge of the A pillar and that was not sticking at all to the windshield when removed.

Picture seven shows the damage done to the windshield by the A pillar vibrating against it over time. Yes, that is a thin lined groove in the windshield and was actually in three places on it.

Picture eight is after the 3M tape is removed and after using denatured alcohol to remove any left over adhesive from the tape. Also need to clean the windshield off in the area where the 3M tape is suppose to stick with the denatured alcohol.

Picture nine shows the new one half inch wide 3M tape replacing the old tape. Got to get it as close to the edge as possible but just far enough away to not make it noticeable, about a sixteenth of an inch maximum from the edge I would guess.

Picture ten is of it all back together, just reverse the process. Took me about an hour or so to complete it on one side.

Planohummer, That could be true I just went by what the service manual said to get the molding off.

Sportsdude, Your welcome and you might want to consider the other options posted here for help also.

I've found using RTV in place of the 3M works and lasts longer. Never seen A repeat failure when done this way.

USING SILICONE: How difficult is removal/cleaning/reinstallation of pillar after using silicone? (considering how often the windshields get cracked, this might be a regular event!)

[KenP]

I suspect that if you have great adhesion, you could use a razor to cut the molding free of the windshield. Then trim the excess silicone off the A-pillar.

Thanks for sharing this way back when. Mine is doing the exact same thing and I have had one helluva time finding the culprit.

[Easy Ed]

You are welcome. Did ya fix it yet and which fix did ya use ?

I used the silicone yesterday...no issues at this point...no mess like i was thinkin there would be...keep ya posted on issues...if any...

[jmsspratlin]

Yeah, got it fixed. I will find out how it holds up in a few days when I get it out on the interstate. Usually it acts up at 70+ mph

I can't imagine this hasn't been tried, but so far it works for me....please let me know if you have done it, did it work, and why shouldn't I have taken this seemingly easy route...but after cleaning the vertical edge between the pillar trim and windshield, I purchased black silicone sealer for windshields or sunroofs, cut the screw on tip so that I could squeeze out a bead of silicone as small as allowable,(1/8")and gently lifted the edge of the trim at the top with my fingernail, I then inserted the plastic tip underneath the edge at the top with the tube at approx 45 deg upward, the trim does flex, and drag and squeeze ample amounts underneath from top to bottom. Pull out at finish, gently press trim so as to spread silicone out underneath and finish with smoothing any that will inadvertently ooze out. This is good because now you have just adhered trim down, and sealed the line between glass and plastic which will prevent the air from lifting and fluttering said trim. Works for me.....so far.

While an older post, I just finished mine with great results. I did not remove the air intake covers and the entire job took me about 20 minutes (both sides). Thanks to the author! :perfect10s:

Funny that you bumped this thread today. TODAY while driving I was hearing this rattling coming from what I thought was the dash or the outside airbox cover. I pressed down on it a few times and I thought it went down some, and the noise went away. Naturally I thought that was it. Looks like it wasn't.

Is this something covered under warranty?

Glad that folks are using the search and finding help here on the site. Congrats getting it fixed.

If you have a warranty left yet then yes it should, is a common problem.

Nice! It's going in for a few other things next week, I'll add it to the list.

I see you're just about an hour north of me. Recommend a dealership to use and those to avoid?

Thanks!!

[Easy Ed]

Cannot help ya there, I haven't been to a HUMMER dealership or any other dealership since my warranty ran out on my 2003. Been lucky enough and able to do repairs myself with the input and help from this forum :D

Easy Ed, just a quick thank you for a well detailed post. Your pics made the job very easy. My H2 pillar molding did not start vibrating until the last couple of trips. I left the old double sided tape on, cleaned it with denatured alcohol and then ran a quarter inch bead of silicone on top of the old tape. Easy, peasy.

Just found this thread after my new to me SUT starting having the wind noise issue. The truck has only 18K miles (2005), but I guess due to the age of the truck, it was overdue.

This DIY fix took me about an hour for both sides, and honestly the longest part was removing the old adhesive strip from the trim pieces.

The only thing I can maybe add is be sure to buy the OUTDOOR rated double sided tape. I used Scotch tape 1 inch wide, and I also noticed that the 3m/Scotch outdoor rated tape will have the red backing affixed to it.

After the install, I used some clamps on the trim & frame to make sure it stuck, for about 45mins while it sat in the garage.

Two days later, I was out on the highway at 80-85 MPH and NO wind noise!!!!

Thank you for this excellent write up!!!!
