Hi,

My '17 Disco HSE blows cold air in the driver footwell no matter what temp setting I have for the HVAC.
A/C on or off, temp set to 59 or 80 degrees - doesnt matter.
Setting the heat on "Hi" makes the air hot also in the footwell.
If I deselect the footwell and only direct air to windshield and the dash vents, there is no air coming out of the footwell.

I have a feeling there's something up with the duct air temp sensor in the footwell, making the HVAC module think it's hot in the footwell.
Have anyone replaced this sensor?
Should be part number LR041044, I believe.

 

This seems to be resolved.
I pulled and replaced the air duct temp sensor in the driver side (US) footwell, and also removed and cleaned the interior air temperature sensor.
Not sure if the air duct sensor or the temperature sensor was the issue, but problem seems to be resolved regardless.

 

Just saw this and I seem to have a similar issue. Where was air duct temp sensor or is it fairly obvious once you take the panels off? What part number did you get?

Where is the interior air temp sensor? What did you use to clean it?

Thank you.
