Rattle wind noise from A-pillar glove box area?

Deuce16GMCs · May 30, 2023

Has anyone else with 21+ had a rattle/wind noise coming from the bottom of the passenger side A-pillar or behind the glove box or the passenger side firewall area at highway speeds of 80 mph or above?

Probably another area where spot welds aren't made correctly, then covered up. LOL

That sounds unfixable.

Just a joke.....ish. some had welds that leaked above the windshield.

I would look at the grill that lays down below the windshield by the wipers. Maybe the wiper blades themselves. Or, possibly the cabin air filter cover.

If it sounds like the area you described, does the noise only happen at a certain mph? Does wind affect it? Can you hear it anywhere else if you sit in the passenger seat? Sometimes noises have a way of traveling and from the driver's seat it sounds " right there"

It's definitely coming from behind the glove box. Someone told me there's a bulliten stating that there's a rattle caused in the passenger side fire wall from a plastic cable harness thing.

It's happens at highway speeds over 80 and it's especially loud when there's a cross wind hitting the passenger side.

Hoping someone has more information on the bulliten. I can't find any info on it.

Noise near front passenger at high speeds (22 Denali): Anyone else?

When rolling dow the interestate at 80+ mph, I hear some weird knocking/tapping sounds coming from the passenger front. They sound outside. My wife was riding with me yesterday and commented on it. At first I dismissed it as crazy wind noise (which does not sound like wind noise at all), but now...

Thank you. The dealer checked the heat shield and said all the clips were good.

I'm going to check the AC lines.

I think I know what it is.

Where can I go to find a copy of a TSB?

I'm going to look at these items on the TSB. I have a rattle that happens above 70 mph on both sides and to me, it sounds like it's coming from inside the A-pillar. I had the sunroof drain TSB resolved and I think it could be those lines. This noise doesn't happen if it is raining which leads me to believe it's those lines. Do they run through the A-pillar?
