BMW 64116972165 Automatic Air Conditioning Control

Heating and air-conditioning functions are programmed via the A/C Switch in the center of the dashboard, which includes air vent control for windshield, face level, and foot level, as well as driver and passenger temperature selection. The LCD display panel shows automatic blower speed mode, AUTO mode, and actual blower speed numerically and with bars. The windshield defroster maximizes defrosting and activates the rear defroster, while the NC compressor control manages the cooling system. The recirculation feature toggles between fresh and recirculated air, with an automatic recirculation control that responds to high levels of exterior air pollution. The rear window defroster operates for a set duration based on outside temperature, and the interior air temperature sensors on both the driver and passenger sides continuously monitor conditions. Air volume can be adjusted through a toggle switch, and the residual heat feature allows for heating the vehicle interior for a limited time after the engine is off. The automatic operation button overrides manual settings for preprogrammed cooling and heating. If the control module is replaced, it is essential to recode using appropriate BMW service tools.

To unlock the IHKR A/C Switch, one needs to use two pieces of plastic prying tools and remove it, disconnect the electrical harness connectors and the Bowden cables at the back side of the switch with attention to the colors. Some included cables that need to be connected to proper control levers during the installation process during the reinstallation the same cables may also need to be properly connected for the machine to perform the intended function. For the IHKA, open the A/C Switch, using a plastic prying tool utilised in BMW, but if one is not available, any similar thin plastic such as a credit card will suffice. Remove the module harness connector by unlocking the connector lock by inserting a thin screwdriver by the connector lock on both sides to unlock it.

Exercise caution as the right side harness connector is permanently attached to the gear position neutral safety switch, so avoid pulling on it.
