What would cause poor air flow out of 4 of 5 air vents in 99 Jeep Grand Cherokee Limited?
I have a 99 Grand Cherokee Limited / dual zone climate control. Air flow out
of driver's side CENTER vent is great. But, air flow out of passenger side
CENTER vent, driver's left vent and both passenger side vents has really
poor air flow. Just replaced blend doors and they work great but still weak air
from 4 of the vents. Blower motor appears to work normally. So, what would
cause the air to blow normally out of just one of the 5 vents??
