So on My 2001 Gmc Z71 Im getting little to no air flow from my vents. It will switch between hot and cold fine. Also will go from floor to defrost to face vents fine. I can hear the blower fan running good and when I took a cover near the fan off, i got lots of air flow there. Any ideas would be helpful of what the problem could be. Thanks.
