The defrost vent on my 2019 Trail Boss is always on, even when I turn it off using the mode button. This occurs when the AC button is off too. Any DIY fix to resolve this? It gets way too hot around my head when running the heat.

find the mode door actuator, and see how it's moving, and perhaps try manually moving the levers for the doors to see what might be the problem (if any).  maybe that's just how it is, maybe a door is jammed open for some reason, maybe the actuator isn't moving properly.

there is a way to reset the climate control, google it

Why don’t you just share the info?

Note, that's the AI results for a google search, which are commonly wrong...  In particular, I would expect the a/c relay to be controlling the compressor, and removing it would not have any effect on the hvac system other than the compressor not coming on, when commanded to.

      2010 Avalanche 5.3 not running correctly after engine swap.

      By contrabombarde · Posted

      I went through again with a test light and everything checked out.    I suppose it could be the MAF itself but I've tried 3 different sensors, 2 of which were in running vehicles previously (the one in this truck, and the one in the donor truck), as well as a new one I picked up from NAPA. I would just be surprised if all 3 were bad.   EDIT/UPDATE: I swapped in the MAP sensor that was originally with the 2010 PCM, that made the code for map sensor voltage high Go away, and the map sensor seems to read normal with key on engine off (14psi or so), but it still doesn't run and does the same thing as before.

      No Software Updates - Old Build

      By Atlas · Posted

      In addition to a cell or wifi connection, the infotainment needs to be enabled to download software updates. That's a toggle within the system settings.   But...if the truck was prevented from receiving updates in a past life, missing a bunch of updates may mean it won't go back and download all of those because they're not available or the system is too far out of date.   If a formal recall depends on a software update, the recall for that truck remains in an open status until it's applied. The dealer would need to apply the software update in that instance.   Most updates downloaded and applied via the infotainment aren't recalls/safety recalls, they're enhancements and usability fixes which aren't critical.

      Brake Pad Warning Message

      By Vu1can · Posted

      Recently I've been getting a message, "New Brake Pads Detected. Reset Brake Pad Life?", But I haven't had the pads replaced and the truck only has 28,000 miles. The Brake Pad Life shows Front 64% and Rear 79%. I select NO to resetting the brake pad life and the message goes away but comes back at the nest restart.   I stopped by the dealer and was told that it sounds like a software glitch that would require reprogramming. Even though I have the extended warranty, they tell me that reprogramming is not covered unless a module was actually bad and needed to be replaced. Simply reprogramming is not covered. So, they want $200.00 just to diagnose the problem. If it turns out no bad module, another charge on top of that to do the reprogramming. If the cause was an actual bad module, everything would be covered under the warranty.   Just wondering if anyone else has had this problem. Should this issue be covered under the warranty?   Thanks

      NHT is diesel only, correct.     The GVWRs for NHT on 3/4 ton bring them to the same numbers as many of the 2WD 1 tons.  A crew 4x4 standard 3/4 with NHT is 11,750lbs, a 1 ton same cab/box/4x4 is 12,100lbs.     Hubs and hub bearings are the same for 11.5" and 12" axles.  Housing, diff carrier and ring/pinion are larger for the 12".   All gas use the 11.5" axle, 3/4, 1 ton and 1 ton DRW.
