Just a bit of information I learned today. Took my 2022 2500 through a car was today. When exiting the wash under the car drying blowers my HVAC vents stopped blowing. Went through a lot of trouble shooting with no results. Come to find out the blowers had forced water into the air intake on my HVAC and soaked my in cab air filter. Guess what a wet filter doesn’t allow?? Air to move through it. Easy 5 min fix after two outs of research and trouble shooting.
