Climate Control Thermostat Not working

Hi All, Apologizes if there is already a post for this. I searched but did not see anything on the forum here like the issue I'm currently having.
I have a 09 Sypder GT. Noticed yesterday when driving that even when the heat is turned up to Mid 20 Celsius (77F) the climate control is blowing cold AC air. The outside temp was mind 50s F. The AC does not shut off till I max the heat at which time the heat kicks in at full. Basically the heat/ac is now an on or off switch. Guessing the thermostat that controls this is toast. Has anyone else had an Issue like to or can lend some insight to my situation?

Thanks

After doing some more research I have a feeling I need to replace the Temperature Control Module. mfg part # MN162847HA. I assume the thermostat it uses is built in?

Auto. I can get the manual versions from a local wrecker but not sure if it will fit?

Ohh, did you do a code scan on the A/C system?
Yeah I don't think you can swap one system to the other

I haven't done a obd2 scan if that's what you are referring to. Not getting an engine light on the dash.

Nope an advanced scanner that can read A/C codes; it’s been discussed many times now; there will be no dash light, and a generic OBD reader can’t read it

There is an servo control that mixes the cold and hot air, basically controlling the temperature. They have a habit of failing. If you can stick your head under the dash on the glove box side. Look up and towards the center consol. You should see the control. Move the temperature control from hot to cold and back again. The servo should move.

The part number is: MR958193

If you turn the key to on without starting the engine, then move the knobs, I can personally hear the motor move with my ears on the foot/head one, and also turning the recirculate one on and off

Better yet, with a proper scan tool that can read live data from the A/C module like my Autel DiagLink, I can see the commanded position of the motor according to the current position of the dial, and then what the potentiometer inside the motor perceives the current position of the motor actually is, they should be matched up pretty close

Then u can see when you move the knob the commanded position changes instantly, and the actual position will move to that same number as the motor moves to that position

If these aren’t matching up because of a faulty motor of potentiometer, u most likely already have a fault code stored in the A/C module for it anyway
