Blower Control

WARNING: This page is about a different car, the 2018 Land Rover Discovery and 2017 Land Rover Discovery. However, it is still accessible from the selected car via links, so may be relevant.

When the system is in the automatic mode, the Automatic Temperature Control Module (ATCM) determines the blower speed required from a comfort algorithm. When the system is in the manual mode, the ATCM operates the blower at the speed selected on the Integrated Control Panel (ICP) or Touch Screen (TS). The ATCM also adjusts blower speed to compensate for the ram effect on inlet air produced by forward movement of the vehicle. As vehicle speed and ram effect increases, blower motor speed is reduced. The blower motor speed will be increased as the speed and ram effect decreases.

3 Zone Climate System

The blower switch on the Rear Integrated Control Panel (RICP) controls the blower in the climate control assembly in parallel to the blower switch in the Integrated Control Panel (ICP).

4 Zone Climate System

The blower switch on the Rear Integrated Control Panel (RICP) has no control over the blower in the climate control assembly. Instead, the ATCM adjusts the rear distribution doors to increase the air flow through the rear distribution ducts from the auxiliary climate control assembly.
