A/C Compressor Cut-Out
WARNING: This page is about a different car, the 1996 Mercedes-Benz C280 and 1996 Mercedes-Benz C220. However, it is still accessible from the selected car via links, so may be relevant.
The A/C-heater control panel receives a speed signal from the A/C compressor speed sensor. If the A/C compressor is seized or hard to turn, the drive belt is protected by disengaging the A/C compressor. The A/C compressor clutch receives voltage directly from the ACC push-button control module (A/C-heater control panel).
