Bad wind noise from truck door

New weather stripping and a door adjustment at a body shop should do it. Of course if the door is sprung out of shape, you might need that fixed. Some types of weather strip can accept a length of surgical tubing inside to help with sealing.

are you sure it is from the door, and not the trim on the side of the windshield? the reason I ask is that there is a TSB for wind noise, my 04 had it. cause wasn't the door, but the strip on the side of the windshield that would start vibrating with wind in certain directions, sounded like wind noise but it wasn't. the sound was amplified by the glass.

If it is loose, they apply VHB tape to it solved the problem. as the weatherstrip gets looser and looser, the noise keeps getting worse.

I swore it was wind noise from door weatherstriping, but after seeing the TSB and doing that, noise was GONE.

a bug deflector can make the noise worse, but it does happen without it as well.

tsb:
Some customers may comment on noise coming from the windshield and door area.

Correction
Replace the left and right side windshield reveal molding. Refer to the Windshield Side Reveal Molding Replacement procedure in SI.

The way to tell if it is the door weatherstripping is to close the door on a dollar bill on various spots around the opening and try to pull it out. It should have some resistance to pulling, if it doesn't your door needs adjustment. You should check the known good side first so you know what it should feel like.

I've adjusted the doors on a few trucks. The procedure varies and is hard to describe, but after the hinges and striker plates are checked and adjusted, sometime you have to bend the window frame one way or the other with a carefully padded 2x4 to get the gap to close evenly all the way around. A body shop should should be able to do this for you for a minimal labor charge if you catch them in a good mood on a non-busy day, maybe bring donuts.

What he said, adjust the hinges.

look at the stud on the door frame that the latch on the door wraps around when the door is closed. I had a similar situation on my Ford 250. Somehow the plastic or vinyl that encircles it had either broken or split off and the door would not close tight. Drove me bonkers for a while and I finally figured it out. I could not figure out what to do. Finally the old redneck country boy genes kicked in and I wrapped it in electrical tape (same width) until it was a thick as the missing band - several layers. Worked great and no more noise. The door was not being held closed tight enough.

X2 on the window frame. That's what mine was.

If none of the above works out, take a look at the hinge pin holes. They may have worn themselves out throwing off the alignment.

This is a common problem with older GMs. Lift the rear edge of the door by hand and watch the hinge pins for movement. If they are loose the door is sagging. Another thought is that the striker is out of adjustment, worn, or loose.
To eliminate the w/s mldg put some painters tape along the mldg gap to body and w/s and drive it.

More than likely the door is slightly bent.. YOu will need to inspect the seal and find where it's not sealed.. then grab the door with both hands and.. well, adjust.

Thanks for all the tips!

I tried the "dollar bill" one and found that about a 6" part of the door has much less resistance than the rest. It's around the area that curves downward from horizontal to a slant.

I put a couple of layers of black electrical tape in two places on the door where I thought it would be contacting the rubber seals. Definitely increased the resistance of the bill. Will be driving to a new campground today and will report back the results when I have a Net connection.
