What This Product Does

The evaporator is the heat exchanger in the cabin cooling assembly. Refrigerant passing through it takes up heat from the surrounding airflow. The expansion valve controls refrigerant entering the evaporator; it is a separate component and should not be confused with the evaporator itself.

Functions

Transfers heat from cabin air into the refrigerant circuit.
Cools air passing through the climate-control assembly.

Technical Details

Supplied part reference: 96457390100.
Installation location: inside the bulkhead.

Symptoms of Fault

Cooling gradually weakens following a refrigerant recharge.
Vent air remains warm or cabin temperature becomes inconsistent.
A musty odour develops around the ventilation system.

These symptoms do not establish an evaporator fault on their own. Moisture-related smells may require cleaning rather than replacement, while cooling problems can also originate elsewhere in the refrigerant system.

Why Replacement Matters

A leaking or corrosion-damaged evaporator can allow refrigerant to escape, leaving the air conditioning unable to maintain cabin cooling. Repeated recharging does not repair the underlying leak. Confirming the source before replacing components helps distinguish an evaporator problem from faults involving hoses, the condenser or the expansion valve.

FAQs

Will a recharge resolve weak cooling?
It may help temporarily, but recurring refrigerant loss calls for leak diagnosis and repair.
Should the expansion valve also be renewed?
Consider its condition while the assembly is accessible. Replacement should follow inspection, rather than assuming both components have failed.
Which supporting parts need attention?
Check seals, O-rings and the receiver-drier when planning the repair. If contamination is suspected, assess whether further system cleaning is necessary.

Air conditioning (Air Con) evaporator and blower motor set. Porsche 964 / 993

AIRCONKIT18.1

Product Information

Air conditioning (Air Con) evaporator and blower motor set
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

Function
The A/C evaporator (96457390100) cools cabin airflow by absorbing heat from the incoming air via refrigerant circulation, delivering cold, comfortable air inside the vehicle.
The blower motors (96457201501 & 96457201601) generate and control airflow through the ducts and across the evaporator, ensuring you feel cool air at the vents when the A/C system is on.
The pollen (cabin) filter (99357247900) helps clean the air drawn into the cabin by removing contaminants and allergens, improving air quality and passenger comfort.
The expansion valve (92857312305) precisely meters refrigerant entering the evaporator, controlling pressure and cooling efficiency. Without proper metering, the A/C system can under-cool or freeze up.
The O-ring seals (99970743441 & 99970725141) ensure all refrigerant joints are sealed tightly, preventing loss of refrigerant and maintaining system pressure for effective cooling.
Air conditioning components degrade over time due to heat cycling, moisture exposure, and refrigerant pressure changes. A worn or failing evaporator can leak refrigerant or lose cooling capacity. Existing blower motors may weaken or fail completely, reducing airflow and cabin comfort. A clogged pollen filter restricts airflow and can circulate dust and allergens inside the cabin. Faulty expansion valves cause inefficient cooling or frost build-up, while old or hardened O-rings lead to refrigerant leaks, hurting system pressure and cooling performance.
Replacing these with quality OE Match parts and genuine seals ensures correct fit and restores the cooling system to its intended performance - keeping your cabin cool, comfortable, and leak-free all season long.
Recommend replacement if you observe:
• A/C blowing warm air or weak airflow
• Reduced or inconsistent cooling performance
• Unusual blower noise or motor failure
• Noticeable dust or odours from vents
• Moisture or leaks in evaporator area
• Difficulty maintaining A/C set temperature
• As part of a full A/C system service

Developed specifically for enthusiasts who want modern A/C efficiency without compromising originality, this advanced evaporator solves many of the common issues associated with ageing factory systems while significantly improving cooling performance with modern R134a refrigerant.

As Porsche 964 and 993 models continue to age, factory evaporators often become clogged, corroded, inefficient, or leak over time. A common issue on these vehicles is the appearance of white flakes or dust particles blowing through the cabin vents, caused by oxidation and corrosion inside the evaporator core.

Unlike modern aftermarket solutions, many replacement OEM evaporators no longer feature the original anti-corrosion coating due to environmental restrictions. As a result, even new OE units can begin oxidising shortly after installation, causing premature deterioration and recurring “white flake” issues.

The CSF evaporator was engineered specifically to eliminate these problems permanently while also improving cooling performance.

Modern Performance Cooling Technology

Leveraging decades of experience designing high-performance A/C condensers, CSF applied modern engineering and manufacturing techniques to completely redesign the original Porsche evaporator.

Working alongside Porsche specialists and development partner Motorsport Inc, CSF extensively tested and compared:
• Original OE evaporators
• Brand-new OEM replacement units
• The now-discontinued Griffiths evaporator

The result is a modern OEM+ evaporator that:
• Fits better than factory units
• Seals more effectively within the HVAC housing
• Provides significantly improved cooling efficiency
• Delivers superior long-term durability

Key Features & Improvements

• Designed for Porsche 964 and 993 models
• Modern parallel-flow dual-core evaporator design
• Approximately 2x greater cooling performance vs new OEM units
• Optimised specifically for R134a refrigerant systems
• Improved airflow and HVAC sealing efficiency
• Super-high pressure multi-channel microtube core technology
• Anti-corrosive powder-coated finish
• Eliminates common “white flake” vent issue
• More durable than factory evaporators
• OEM+ fitment and factory-style integration
• Lower cost than genuine Porsche replacement units

Why the CSF Evaporator Performs Better

Modern Parallel-Flow Core Design

The original Porsche evaporator uses outdated serpentine-style core technology originally developed for R12 refrigerant systems.

The CSF evaporator upgrades this to a modern parallel-flow dual-core design featuring:
• Increased surface area contact
• Improved refrigerant flow efficiency
• Enhanced thermal transfer
• Superior cooling performance with R134a refrigerant

No More White Flakes or Cabin Dust

One of the most frustrating issues on Porsche 964 and 993 models is white dust or flakes blowing from the dashboard vents.

This is caused by oxidation and corrosion inside the evaporator core.

The CSF unit solves this permanently with a durable anti-corrosive powder coat finish that protects the evaporator from moisture, oxidation, and corrosion — ensuring long-term reliability and cleaner cabin airflow.

Better Fitment = Better Cooling

Testing showed the CSF evaporator seals approximately twice as effectively as OEM or discontinued aftermarket units.

A superior seal improves airflow through the evaporator core, resulting in:
• Colder vent temperatures
• Improved cabin cooling
• Better HVAC system efficiency
• Reduced strain on the air conditioning system

Why Upgrade Your Porsche 964 / 993 Evaporator?

Restore Modern Cooling Performance

Designed specifically to improve R134a system efficiency.

Improve Long-Term Reliability

Eliminates corrosion and common evaporator failures.

Reduce Future Repair Costs

The evaporator sits deep within the HVAC suitcase behind the dashboard, requiring extensive labour to replace. Installing a long-term solution now prevents repeat failures later.
