Over the last week or so I noticed my driver side vents started blowing hot air, no matter what setting the driver’s side is on. It seams like it gradually got worse.
Is the the blend door issue. The rear vents are warm as well. No cold air thru the console.
I can actuate the airflow thru the defrost, upper, and blend on both sides.
I was told at the auto parts store there are 4 blend doors.
It’s a 12 inch screen model so removing the radio is not a big deal, but I wonder if I have to pull it out and how to figure out which one is bad.
My local dealer can see me till September and now it’s July!
From what I can tell the blend doors are suppose to control the air temp, but I wonder which one. What’s the probability that the drivers side and rear went bad at the same time.
Could it be a software issue? There was an update that was applied successfully in April.
Thank you for your suggestions!
