When compressor locks < vehicles with 3.0 L engine >

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

Since the compressor and alternator are driven by the same belt, the electric generating function of the alternator also stops when the belt is broken. In order to assure the electric generating function of the alternator, there is an automatic compressor controller to prevent breaking of the belt due to slipping when the compressor locks. The automatic compressor controller makes a comparative calculation of the compressor revolutions and the engine revolutions which are detected by the revolution pick-up sensor. When 70% or more slip ratio continues for 3 seconds or more, the A/C compressor clutch relay goes from on to off; at the same time, the operation display in the air conditioner switch blinks to announce an abnormality.
