auxiliary relay panel I, picture 610-8
A/C control relay
the relays from right to left in the box (towards the engine):
normal speed fan relay
high speed fan relay
Headlight / fohlight cleaning system module (empty in case not ordered as option).
E-box fan:
the box is cooled by a 2-speed electric fan. The fan rund at low speed when the engine is running. If the temperature in the box exceeds 44 degree C., the fan will run on high speed.
