Hi,

I have a 1993 Suburban that I just bought. The heater control doesn't seem to work. The fan turns on but will blow only air out of the dash vents. It won't blow any air out of the defroster vents or the floor vents. Anyone know whats wrong with it? Is it the control panel itself or something other under the dash?

Thanks in advance!
