Heating dial not working properly
Is it an electric switch controller or the mechanical type found on the startline model? I've heard of problems on the mechanical ones with the cables braking.
Heat to the screen is either hot or cold, no in between.
It thermostatic, set it to a temperature and the system will maintain the temperature. This will mean initially you will get hot air untill the cab reaches the set temp and then it will cool off as needed to maintain the temp.
Even with aircon off?
As @Insert Coin says, when you're on the 'screen' or 'demist' (12 o'clock on the dial) setting it overrides the temperature setting. Turn it to feet, dash vents or any combination of these and the thermostat takes over.
Yes
Another T6 school day. Cheers.
This is correct. Heating set to 12 o'clock is 18 degrees. If the cab temperature is below 18 degrees then the heat will be full blast until the cab temperature reaches 18 then it cools off. I find this more noticeable in the summer as the heater will blow cool after a short time as the ambient air temperature is higher.
