Hi guys I am a new boss hoss owner from Scotland, I have an issue with my boss boss where the electric fan pulses on and off rapidly, has anyone else had this before? I have changed the relay to no effect (assuming this is a regular 5 pin relay), removed the connections on the temp switch on the intake mani and bridged them with wire which makes the fan run full power, as soon as I stop bridging them the fan goes back to pulsing on and off regardless if it is connected to the intake temp switch or not. Does anyone have a wiring diagram for a 2005 zz4 it would be much appreciated.
