incl. Expansion valve and o-ring seals.
This comprehensive air conditioning (A/C) system service kit bundles key HVAC components required to restore or upgrade the A/C performance in classic Porsche 911 (964 / 993) models. It includes the OE Match evaporator core, blower motors, expansion valve, and genuine O-ring seals necessary for correct installation and leak-free refrigerant performance.
Fits:
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998
Diagram Ref No 5, 34, 35, 37 and 38.
This A/C service set is a combination of essential climate control components engineered to ensure your Porsche’s air conditioning system delivers reliable, cold airflow and maintains proper refrigerant flow throughout the system. The kit is ideal for A/C system rebuilds, evaporator replacement jobs, or when multiple HVAC components show wear due to age, moisture exposure, or refrigerant system fatigue.
Kit Includes:
• OE Match A/C Evaporator – OE ref no 96457390100
• OE Match A/C Blower Motor – OE ref no 96457201501
• OE Match A/C Blower Motor – OE ref no 96457201601
• OE Match A/C Expansion Valve – OE ref no 92857312305
• O-Ring Seals – OE ref no 99970743441 and 99970725141
This kit is intended for use within the air conditioning system - specifically the evaporator chamber, refrigerant metering, and blower airflow portions of the HVAC assembly.
The A/C evaporator (Part No. 96457390100) cools the cabin air by absorbing heat from incoming air passing through the HVAC system into the A/C refrigerant circuit. As refrigerant enters the evaporator, it expands and removes heat - providing cold, conditioned air for the cabin.
The blower motors (96457201501 & 96457201601) circulate air across the evaporator core and into the cabin through the ventilation ducts. Reliable blower operation is essential for efficient A/C performance and passenger comfort.
The expansion valve (92857312305) precisely meters refrigerant flow into the evaporator, ensuring the correct pressure and temperature for optimal cooling. An effective expansion valve prevents evaporator freeze-up and reduces strain on the A/C compressor.
High-quality O-ring seals (99970743441 and 99970725141) guarantee leak-free connections between A/C components, maintaining proper refrigerant pressure and system integrity.
Over time, A/C evaporators can develop internal corrosion, refrigerant leaks, or blockages. Age-worn blower motors fail to deliver sufficient airflow, and expansion valves can become clogged or lose metering precision. Faulty O-rings degrade and allow refrigerant to escape. This leads to:
• Weak cabin cooling
• Unstable A/C pressure
• Blower noise or failure
• Higher compressor load
• Reduced HVAC efficiency
Replacing these components with OE Match quality parts and genuine Porsche O-rings ensures correct fit, proper refrigerant sealing, and long-lasting air-conditioning performance.
Recommended replacements if you notice:
• Diminished cooling capacity or warm air from vents
• Weak or inconsistent blower airflow
• Refrigerant leaks or low system pressure
• Excessive blower noise
• System not reaching cold set temperature
• During A/C system overhaul or major service

Diagram ref no 5.
• Engineered to match original specifications and fit perfectly, it provides quiet, powerful airflow so your heating and A/C system works like new again.
• Position on Vehicle: Mounted inside the front bulkhead/heater box on the left-side (driver’s side) of the vehicle, as part of the HVAC blower assembly.
• Applications: Ideal replacement when the original blower motor shows signs of failing (noise, reduced airflow, erratic operation) or when restoring the HVAC system of a 964 or 993 model to full performance.
The blower motor is a critical component of your vehicle’s HVAC system - it supplies the airflow needed for heating, cooling and ventilation of the cabin. When the motor wears out or fails, you may experience reduced airflow, noise, inconsistent cabin temperature, or even system shut-down. Replacing it with a high-quality OE-Match unit restores proper air distribution, helps preserve the lifespan of other HVAC components and ensures passenger comfort and safety.
When and why to replace:
• Noticeably reduced airflow or weak ventilation in heating/AC mode.
• Unusual noises (grinding, squealing, or rattling) coming from the blower motor or vents.
• Motor does not run or runs intermittently, especially when HVAC is switched on.
• Replacement of related HVAC components (evaporator, heater matrix or ducting) where the blower motor is readily accessible.
• Older vehicle (high mileage) where the original blower motor has been in service for many years and may be nearing the end of its life.

OEMatch Blower Motors & Fans — Fit, Function, Confidence
Blower motors and fan assemblies move air through a Porsche’s heating and air‑conditioning ducts to support cabin comfort, demisting and ventilation. OEMatch supplies replacement blower motors and fan units chosen to help restore reliable airflow and HVAC response for Porsche models, useful when servicing, restoring or upgrading climate control systems.
Available Types
- Replacement blower motor units
- Fan and wheel assemblies
- Blower motor resistor and speed‑control modules
- Complete blower modules with housing and mounting
Understanding OEMatch Blower Motors & Fans
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original blower motors & fans.
OE (Original Equipment) refers to parts matching original specifications for the blower motors & fans and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM blower motors & fans engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Blower motors drive the fan that circulates air through the evaporator, heater core and cabin vents. Correct selection ensures appropriate airflow at each speed setting, quiet running and compatibility with a vehicle’s mounting points and electrical controls. OEMatch provides a broad selection of items for Porsche HVAC applications and continues to extend its range to cover model-specific needs.
Benefits Include
- Restores strong, consistent airflow for heating and cooling
- Reduces noise and vibration from worn components
- Helps prevent windscreen fogging and improves cabin comfort
Why Blower Motors & Fans Wear and Fail
- Worn brushes or bearings causing slow or noisy operation
- Debris or contamination obstructing the fan wheel
- Electrical faults such as failed connectors, resistors or motor windings
- Moisture ingress leading to corrosion or short circuits
The Importance of Replacing with OEMatch Blower Motors & Fans
Replacing a failing blower motor or fan assembly restores effective ventilation and ensures the HVAC system can deliver the temperatures and airflow required for comfort and safety in a Porsche. Appropriate replacements reduce the risk of intermittent operation, eliminate distracting noise, and support clear visibility by improving demist and defrost performance.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Designed to fit original mounting points and clearances
- Compatible with factory control systems and common sensor interfaces
