Air conditioner fan relay. Porsche 924 / 924 S / 944

Air conditioner fan relay. 
The air-conditioning fan relay is used in the cooling and climate-control system of Porsche 924, 924S, and 944 models. This relay controls power delivery to the A/C condenser fan, ensuring the fan switches on at the correct time to support refrigerant cooling and maintain proper system pressure.

Fits:
Porsche 924 1979 - 1985
Porsche 924S 1986 - 1988
Porsche 944 1982 - 1985

* Please check and match the part number of your relay in your car before ordering.

This A/C fan relay:
• Supplies power to the A/C condenser fan whenever system pressure or temperature demands additional cooling
• Ensures stable switching performance for consistent fan operation
• Helps maintain proper refrigerant pressure and improves overall A/C cooling efficiency
• Replaces failing relays that cause intermittent or non-working condenser fans

A faulty A/C fan relay can lead to:
• Weak or non-functioning air-conditioning
• A/C system overheating or high system pressure
• Poor cabin cooling performance
• Erratic or noisy fan operation
• Potential stress or damage to A/C components (compressor, hoses, pressure switch)
Replacing the relay restores proper climate control performance and ensures the A/C system operates safely and efficiently.
