06 GT no heat?

Both of mine have floor heat. That is definitely not normal.

Heat

NOT NORMAL

Not normal, no way.

There should be heated air coming out of the floor vent. It's possible that the diverter inside the airbox that directs the air to the different locations is either binding, or an object is blocking its movement.
See what another dealer says.

Definitely not normal, in fact without any ventilation on at all after a long drive on a warm day it can get downright warm in the footwell.

Alright I'm tired of listening to my wife moan about how her feet get cold in her 06 GT, because it has little to NO floor heat.

Get a different wife. Keep the Stang.

Hmm, I have this as well, but I live in the south. Only on the coldest of winter nights has it been a concern. Doesn't bother me.

Not normal at all mine are kinda always on.

Mine was the same way when I got it. I took it back to the dealership and after looking at it for a while he pulled forward the glovebox and there was like a 8 (can't remember exact number) wire connector sitting behind it simply not connected. He plugged it in, and voila heat. I hope this helps.

whats normal is the dealership cant figure it out and lies to you. thats perfectly normal.

Did you get the problem fixed?

mine had this problem, first they did something which didnt fix it, then they changed the climate controls, now it works perfectly.

The air distribution is no longer a vacuum system. The SJB controls 3 actuators and a recirculation door motor (for fresh air). The actuator for floor air is located just to the drivers side of the centerstack inboard of the instument cluster it is connector C234. It has 5 wires so I would assume that it's a 6 wire connector with one empty slot. Wiring is as follows:

RD-LG V REF ACTUATOR

RD-WH V REF GND

YE-LB PANEL/FLOOR FEEDBACK

GY-LB PANEL/FLOOR CCW

BR-WH PANEL/FLOOR CW

Pinpoint Test B: Incorrect/Erratic Direction Of Airflow From Outlet(s)

Normal Operation
Under normal operation, to rotate the mode door actuator clockwise, the EMTC module supplies voltage to the BLEND, DEFROST and FLOOR/PANEL mode door actuator motors through the door actuator feed B circuits, and supplies ground through the door actuator feed A circuits. To rotate the mode door actuator counterclockwise, the EMTC module reverses the voltage and ground circuits.

The mode door actuator feedback resistors are supplied a ground from the EMTC module by the mode door actuator return circuits and a 5-volt reference voltage on the mode door actuator reference circuits. The EMTC module reads the voltage on the mode door actuator feedback circuits to determine the mode door actuator position by the position of the actuator feedback resistor wiper arm.
