An automatic car-cooler clutch control apparatus such that the compressor can forcedly be engaged with the engine when a predetermined period of time has elapsed after the compressor is disengaged or when the vehicle speed reaches a predetermined value, in addition to when a vacuum pressure within the intake manifold is more than a predetermined value, that is, a relatively light load is applied to the engine. The automatic car-cooler clutch control apparatus of the present invention comprises a timer or a speed indicator including one or two switch circuits for energizing the clutch relay to engage the compressor with the engine, regardless of a vacuum pressure within the intake manifold, in addition to a vacuum pressure switch and a vacuum pressure chamber communicated with the intake manifold.
