What controls the direction of of the fan blower (i.E defrost, floor, etc.) On a 02 Chevy Tahoe? Mines is only blowing on defrost now no matter where you set the control.

Could be something as simple as a system relearn, but could be the mode acuator or the control head itself, to properly diagnose the problem though, you will need to get the HVAC module scanned for codes using a factory compatible scanner, ( a regular code reader does not have the capability to scan this system)
