I can't get my heater to blow heat out the floor vents. I just get heat out of the defroster when it's on mix and I get a little warm air out of the defrost vents when it's on floor as well. Near as I can tell it's a vacuum motor not working as I can hear the vacuum motor activate when I switch it to defrost. I've found 2 vacuum motors under the dash, one appears to be for defrost and the other for vent but I can't find the one for floor. Any tips on where to look or what else it might be? It just started happening all of a sudden, the selector knob for the heater function got some play in it at the same time so it could be in the switch too.
