Anyone else have a high pitch noise above 75ish that is linked to the climate control recirculation? At first I thought it was a windshield air leak. Only does it @ 75mph and up or with high winds with either the climate control off or with the recirculatory air on. Had it to dealer about 2 weeks ago. Tech acknowledged the noise and said they would get with GM on what to do but have yet to get back with me. I did a search and found that it's a vent door not sealing in the climate control. Anyone know if it's accessible through the glove boxes?

Mine does it too, I had a brand new rental with 40 miles on it, did it as well. I figured it was normal.

Dealer just got back with me and gm responded with the go ahead for warranty repair. I asked about if they needed to romove the full dash and I got a "we'll see" answer. I am scheduled next Wednesday.  "We'll see" what happens as they told me over the phone that they are not sure what exactly the will have to do or get into.

Definitely keep us updated. Mine has done the same since day 1. Dealer said they’d probably have to take out the dash. I’m reluctant because I would rather turn recirculation off on the highway than have my dash rattle....

So I finally made it to an appointment to have this checked out. They told me that they took to cowl off and checked the flapper and also took some inside dash trim off and used a stethoscope and determined that the noise is not from the HVAC system. They said there was a lot of wind noise at the bottom passenger corner of the windshield. And that changing the recirculate function is just changing the pressure in the cabin. So now they want to take the windshield out, inspect the area, and reseal the original windshield back.

I've been back to the dealer since they wanted to replace the windshield. After my last post I noticed the dealer broke some trim pieces and glued them back into place. I went in and flipped shit. Plastic breaks, and stuff happens, but to hide it and glue it back together is inexcusable. Went to another dealer afterwards. They will not work on it until what was broke from the first dealer is fixed. Waiting on parts during the strike. I will say that I have played with the HVAC settings some more and my problem has specific requirements on the settings to replicate the sound and that kinda tells me the whole windshield stuff the first dealer told me was a bunch of bull. So far I have no answers.

Oh my! That is terrible. After my last exp in a Chevy dealer... I'm not surprised. It's quite sad these days that they can't do the right thing. It's all about speed, and making the boss happy... not the customer.

This is gonna sound funny. Guys that have complained of this occurring before had to open the rear console air vents. After that they said the sound went away. May want to check those.

I have yet to get this issue straightened out. Dealer recalibrated the actuators but didn't help it. Haven't really played with my rear vents to see if that changes it.

I remember similar issue with mine when new.  Opened all vents (to far up or down up front restricts flow and to far left or right in rear console vents restricts flow). No issue since adjusting.  Current generation System appears to move more air and vent restriction can cause noise for sure.

I have tried all tips and tricks. Nothing seems to help. Stealership is no help!!!  Now it has brake issues as well. Only 4K on the truck.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
