Rear fan airflow issues?
Hello,
I have been chasing down gremlins in my rear ac system and one of them is that the air coming out of the 4 rear ducts seem very low (in volume) when the fan is on the high position. I can hear the fan spinning loudly in the rear but the air seems just like a slight breeze out of the front 2 vents and the rear are only slightly stronger. I had a 00 Ex back in 07 and don't remember how fast the air came out but in my 06 Explorer and 03 Navigator when the rear fan was on high I could feel a good blast coming out all rear vents. What should I start to look at?
FYI I have taken to dealership and they don't see the air flow as a problem while they are chasing the other gremlins.
