08 mega dash air vents
 

my dash vents in the center flow fine, but the outer vents have very little flow. is this normal for this truck or do i need some ******* service.
thanks

i guess most of you are using the defrosters this time of the year.
i hate to bug a dealer if the dash is working normal.
we are already spending a evening on here helping each other.
thanks anyway..

my dash vents are somewhat weak also. i've read that it is a common problem on these trucks.
