Likely cause of no air out the floor vents?

[simanco]

So, it's gotten cold in Kentucky and the 95 GM is not putting ANY air out the floor vents. Panel vents and defroster still work as they should, but with the EATC on AUTO it likes throwing heat to floor.

I have been running it on the VENT setting to get warm air, but I don't like warm air around my head and my toes are freezing ...

When the blend door rod on the Continental broke, we could hear the door flapping around. This one is silent.

I did pull cable up through the dash there for my stereo install -- what are the chances I just dislodged a connection?

Thanks,
Jim

This is a common problem with the heater hose coolant sensor - its designed to keep air from being blown on the floor or when its broken.
Find the sensor and jump/join its 2 electrical wires together and you will have floor heat.
