I have a 98 Pathfinder and I'm having a problem controlling the air flow inside the car. No matter what setting I chose most of the air comes out of the upper vent. The fan is working fine, my problem is that I cannot get too much air to come through the lower vent or defroster ducts.
I have traced the dial down to a cable but I cannot find where it's going. I'm suspecting the problem is with some valve or vacuum switch within the ducts but I don't know where they're located.
If anyone has any ideas where it's located I'd greatly appreciate it.
Thank you!
Mike.
