1999 Mercury Tracer LS 4 Cyl 2.00L
Blower fan works but little air through vents
I can hear the blower fan, and it seems to be working well in all speed levels, but little seems to be coming through the vents. I have read that there is no cabin filter in this model, so it can't be that.
Several possibilities; faulty blower switch, faulty / binding vent diverter linkage, faulty defroster linkage.
