Dear experts,

First thing, it is a safety feature for merc that it will auto switch to take outside fresh-air after 20-30min of driving.

When you feel hot air coming in, take a look at the panal....is the internal-air-circulation light goes off ? if it is, press it to switch back to internal circulation.

Next, check your 4 Zone Thermotronic Control , passenger side and driver side have their own temperature setting. 

Is all the Zone same setting ? Sometime, one of the zone-valve kana stuck...that zone will blow hot air...

Not the Air Con.......air con is super cold all the time. 

Is after you park the car .... engine off and re enter the car. 

Whole car feels warm. even if its at night. 

Feel that there is heat from somewhere...

This is the Climate control that's working in winter condition when engine is off.....it blows hot air from the engine heat for about 10-15min at very low fan speed.

Switch off the REST button....its in the manual.

Rest is not depress.
