Front speakers in and out with vent

Interesting issue. My 2008 2500 with Bose has an issue in that when the vent is blowing at the top (face), the front pillar speakers only cutout. I finally replace to an aftermarket head unit but still the same issue.

It's not speakers as the work perfect when the blower is set to feet or defrost. It only is the front pillar speakers and only when the vent is on the upper vents.

Any ideas?

  +1 for the 3.0 Perfect for 1500 pickup towing duties. Perfect engine for a 1500 pickup period. Huge torque at stunningly low RPM makes it feel a lot lighter than it is. The fuel mileage is insane for a tall and heavy 1500... 30+ on the highway. Mid 20's around town. It's probably not perfect if you bought a 6.2 for the braaaaaaapppppp V8 noises and wrapping it out to 6k. The LZ0 acts and sounds like a small turbo diesel and there's nothing you can do to make a small turbo diesel sound like a big one, and you can't make an inline diesel sound like a V8 diesel/big Duramax. It's a different driving experience altogether. Drive one, I think you'll like it, though...

  I'll bet your truck lost the bearings on a roller on 1 of the lifters, and now is wiping out a cam lobe.
- "Reduced Acceleration, Drive with Care" message for Valve Body malfunction

  2024 2500 gasser with 47,000 miles. Driving on interstate Friday when my truck shudders, downshifts, and I get the above message with check engine light. Transmission would not upshift. I had to drive home 2 hours at 65 mph at 3600 RPM with transmission temps 190-200 degrees. Got it to the dealer Monday. They ran the code and said the #1 valve body was malfunctioning in the transmission. Miraculously, they had the part in stock and I had a new valve body installed that day with new transmission fluid/filter. Thankfully, all under warranty. Shout out to Everett Chevrolet in Hickory, NC.

  My truck rarely sees a dusty, dirt road, if ever. Actually, never. Within 6mo of ownership, mine was totally covered with road dust and yellow, Louisiana pine pollen. I swear, it looks 6yrs old. You'd think it was an oilfield, or pipeline service truck. Did GM just do a piss poor job of sealing the bay? Anyone else with this issue?
