I have the 2 zone a/c unit which doesn't have the same buttons, my heater was fine until a flat battery, now it comes on after about 15 minutes, is there a reset for this model?

To reset the Mercedes W204 AC, insert the key and turn the ignition to the 2 position. Press and hold defrost and recirculated air buttons at the same time for ten seconds. Wait a minute for LED lights to stop flashing and turn off the car. Wait another minute and start the car again.
