OK folks, here an issue I've never come across or been able to find any info on. My 2020 Laramie Crew Cab has developed a really odd wind noise/whistle at speed above 65 mph. It has started during past 1000 miles or so (31k miles on the truck).
The odd part is that it's not caused by outside air trying to enter the cab. It's caused by pressurized air from the HVAC system trying to escape the cab. It blowing past my driver's door seal and the driver's window seal where the glass meets the interior door panel. It stops when the HVAC system is put on "Recirculation" since the cabin isn't being over pressurized or when I slightly lower one of the other windows.
I've foundc the 2 cabin air exhaust vents located in the body pannel near the lower portion of the back doors. They do not appear to be blocked. Nothing is stored under the back seat where I assume cabin air enters the discharge vents. The door seals are good and the doors seem to be perfectly adjusted and tight.
Yes, the truck is still under warranty and I plan to take it in. But I am 1500 miles away from home on an extended trip and am hopping there is a simple issue that I am missing to keep me from getting further irritated on my trip back home.
Any ideas?
