Cooling fans operating sequence
Good morning to all Porsche fanatics and friends
Does somebody know the operating sequence of the cooling fans (left and right,low and high speed) on a 2000 Boxster ? Also which relays are for low and high speed? My right fan only works....all my fuses and relays test Ok..I am suspecting bad ballast resistors... Thanks in advance Michel |
Good chance it's the Ballast Resistor.
Both Fans operate simultaneously whenever the DME calls for it, never singly or at different speeds. The default whenever the AC is operating (compressor turning) is high speed. Low speed is determined by the DME using a number of variables, there is not a simple set operating parameter. Coolant temp, RPM, Speed, even ambient temp all play a part in the DME determining low speed operation. The relays, located in the driver kickpanel are as follows:
