weak floor heat

[rollavvti06]

My heat is hot through all sections but floor its kinda I weak blowing on floor but it does have air flow, all other selections do work ie vent defrost. Would this be that one vent door doing this that I have read about or should I start to see if I have a clogged vent

I have manual heat controls, that's for the digital. But everything thing works like it should but the floor heat is weak, that's why I'm stumped, but its to cold to start tearing things apart

when you put the heat to floor, do you feel it coming out any of the other vents could be the damper for the floor isn't closing fully

When FLOOR is selected:
• The air inlet duct door is in the no vacuum position, blocking recirculated air and admitting outside air.
• The floor/panel door is in the full vacuum position, directing all airflow to the heater outlet floor duct.
• The temperature can be adjusted to mix air flowing through and around the heater core to achieve the desired temperature level.
• The panel/defrost door is in the no vacuum position, blocking air circulation to the instrument panel A/C registers.
• The A/C compressor will be disabled when FLOOR is selected.
• The blower motor is on.

I'm not sure of the location of that door I'll check and see what I can find in the service manual in the meantime hopefully someone that has worked on the syatem can offer some advice

It appears that it is in the plenum in front of the center console where the floor duct connects
