Diagram Ref No 7
Installed within the air-conditioning housing, the sensor monitors temperature around the evaporator and intake-air area and sends this information to the climate-control electronics. The system uses the temperature signal to regulate air-conditioning operation and maintain consistent cabin cooling.
A correctly functioning sensor helps the HVAC system react accurately to temperature changes, prevent excessive evaporator cooling and deliver the selected cabin temperature.
What This Product Does:
The evaporator is the part of the air-conditioning system that absorbs heat from air entering the cabin. As refrigerant passes through it, the evaporator becomes cold and cools the airflow passing across it.
The temperature sensor continuously reports temperature information to the climate-control system so that cooling can be regulated correctly.
Its functions include:
- Monitoring temperature within the A/C evaporator housing
- Sending temperature data to the climate-control module
- Helping regulate compressor and cooling operation
- Supporting consistent cabin temperature control
- Helping prevent the evaporator becoming excessively cold
- Reducing the risk of evaporator icing
- Helping the HVAC system respond correctly to driver temperature settings
- Supporting efficient overall air-conditioning operation
Symptoms Of Wear Or Failure:
Temperature sensors can fail electrically or begin providing inaccurate readings with age.
Common symptoms of a faulty A/C evaporator temperature sensor may include:
- Air-conditioning cooling intermittently
- Cabin temperature not matching the selected setting
- A/C becoming cold and then unexpectedly warming
- Compressor cycling too frequently
- Compressor failing to operate when cooling is requested
- Evaporator icing or freezing
- Reduced airflow caused by ice forming on the evaporator
- Air-conditioning switching off prematurely
- Inconsistent vent temperatures
- Poor or erratic automatic climate-control operation
- HVAC fault codes relating to temperature sensing
- Temperature readings that appear implausible during diagnostic testing
Similar symptoms can also be caused by low refrigerant, a faulty expansion valve, compressor problems or other HVAC sensors, so diagnostic testing is recommended before replacement.
Why Replacement Matters:
- The climate-control system relies on accurate temperature information to regulate the air-conditioning system correctly.
- If the evaporator temperature sensor reports an incorrect value, the control system may believe the evaporator is warmer or colder than it actually is. This can cause the compressor to cycle incorrectly, reduce cooling performance or allow the evaporator to become excessively cold.
- An evaporator that becomes too cold can begin to ice over. As ice builds up on the evaporator surface, airflow through the ventilation system can be restricted and cabin cooling performance may deteriorate.
- Conversely, if the sensor incorrectly reports a temperature that is too low, the system may reduce or stop compressor operation too early, resulting in weak or inconsistent cooling.
- Replacing a faulty temperature sensor restores accurate temperature feedback to the HVAC control system and helps return the air-conditioning system to stable and predictable operation.

Information
Air conditioner series resistor
Air-conditioner series resistor is designed for the HVAC blower control in the Porsche 928 series. Installed within the climate-control system, this resistor pack provides multiple steps of electrical resistance, enabling the blower motor to run at different fan speeds (low, medium, high). Built to match Porsche’s original specification.
Fits:
Porsche 928 1989 - 1993
Diagram ref no 37
• Position on Vehicle: Within the HVAC unit - typically mounted near the blower motor or inside the footwell dash area, functioning as the speed-control resistor pack for the A/C blower.
• Part Numbers / References: OE references 928-616-101-00 or superseded 928-618-101-01.
• Applications: Suitable when the blower motor is stuck at one speed (typically high only), blower fails on low/medium speeds, or after servicing blower motor or climate control system.
While compact, the A/C blower resistor plays a vital role: degraded or failed resistors commonly cause the blower to be stuck on high only or no low/medium speeds - impacting comfort, defrost performance and cabin ventilation. Replacing with the correct resistor restores full speed control, safer driving (better defrost), improved comfort and avoids fan motor overdrive.
When to replace:
• Blower only runs on high speed or fails at lower speeds
• A/C or heater airflow is weak despite servicing the blower motor
• Blower control selector has no effect or is inconsistent
• You’re servicing or replacing the blower motor or HVAC system in your Porsche 928
