The switching on and switching off of an air conditioner is primarily determined by signals which are supplied by a temperature controller. However, operating conditions are present wherein the temperature controller supplies the signal "on" but that the operation of the air conditioner is nonetheless unwanted so that the torque of the engine can be available for driving the vehicle. The fulfillment of special conditions for switching off and again switching on the air conditioner are therefore investigated when temperature switch-on conditions are fulfilled. According to the method of the invention, the air conditioner is switched off when the accelerator pedal position exceeds a switch-off threshold value and the difference between the actual permissible full-load quantity and the actual correct idle quantity is less than a predetermined minimum difference. The air conditioner is again switched on when either the accelerator pedal position lies below a switch-on threshold value for at least a predetermined time duration or when the engine speed exceeds an rpm threshold value.
