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.

OEMatch relays, sensors and resistors for Porsche models help regulate blower motors, temperature control and other electrical functions within climate and auxiliary systems. These components manage electrical flow, monitor conditions and adjust motor speeds to keep cabin systems responsive. OEMatch relays, sensors and resistors are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable.
Available Types- HVAC relays for fan and compressor control
- Blower motor resistors and resistor packs
- Cabin temperature, ambient and evaporator sensors
- Pressure and switch sensors for system monitoring
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original relays, sensors and resistors.
OE (Original Equipment) refers to parts matching original specifications for the relays, sensors and resistors and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM relays, sensors and resistors engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Relays, sensors and resistors control electrical power, provide feedback on temperature and pressure, and regulate motor speeds. Failures commonly result in intermittent fan operation, incorrect cabin temperature readings or complete loss of heating and cooling. OEMatch supplies a broad selection of Porsche-focussed parts and continues to develop new lines to support climate and electrical system repairs across model generations.
Benefits Include- Restores accurate fan and temperature control for consistent cabin comfort
- Reduces risk of electrical faults that can lead to blown fuses or motor damage
- Aids diagnostic accuracy when troubleshooting HVAC and electrical systems
- Corrosion or oxidation on terminals and connectors impeding electrical contact
- Overheating or short circuits from electrical surges damaging components
- Moisture ingress, condensation or environmental contamination
- Age-related sensor drift and resistors burning out under sustained load
Replacing worn relays, sensors and resistors restores accurate climate control, prevents secondary electrical damage and reduces the chance of intermittent faults that affect comfort and system reliability in Porsche models. Timely replacement supports correct diagnostics, avoids unnecessary component changes and helps maintain consistent operation of related systems.
Advantages- Manufactured to original-spec dimensions to fit factory mounting and connectors
- Designed for thermal and vibration resilience typical of vehicle environments
- Can be fitted using standard procedures; follow model-specific guidance for torque and reconnection checks
