I have this exact same issue, well it's in reverse. External temperature is about 85f. My drivers side vents blow cold and passenger side blows hot. It does not matter what temperature setting is set. I tried everything from both lo and max to max on the passenger and 75 on the driver. Same result every time, hot out of the passenger upper vents and cold out of the drivers upper vents. Tried starting the car with ac system off also. Any thoughts would be appreciated. My edge is out of warranty due to mileage.
Anyone know of TSBs or have dash removal procedures?
