Was wondering if there was a programming thing I needed to do to increase the air flow out the passenger side air vents. Air from the driver side come out just fine. Van has both Driver and Passenger side controls.

Thanks for your help.

It may help. Good luck.

This worked great, now air comes out both sides like it should. Thanks for the info.

You're welcome and thanks for the follow-up.
