Normal Operation

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

When the instrument cluster detects a headlamps ON message, it sends a variable voltage to the climate control assembly through circuit 19 (LB/RD). The climate control assembly is grounded through circuit 57 (BK).
