Hey Scotty. I have a 2017 Toyota Tundra SR5 Supercrew with 68k miles on it. I just bought back in February. I live in northwest Ohio so it gets pretty cold around here in the winter. When that snowstorm hit around Valentine’s Day, I noticed that when I turn the vent selector knob to adjust the blower, it comes out the dash vents or defroster vents no matter where I set it. Do you think it could be the blend door actuator or something in the controls? Thanks.
It may have been your electronics acting up, in the cold weather.
Does it still do it now (or in warmer weather)?
