928 Fan Controller Repair


Porsche cooling fans in a 928-S4, GT or GTS model are operated by a power stage that often fails after many years of service. The power stage is located in front of the engine compartment.

Common symptoms of a broken 928 fan controller are:

  • One fan is running at full power while the other fan is not running at all.
  • Both fans do not run.

  • 928-ecu-repair repairs the fan power stage and make it run within specs again. Repair involves sending in the broken unit and get a replacement unit in return.
