Fan switch, bad earth ?
Fan wont come on at all unless its hardwired now.
Just really paranoid its not headgasket after all the googlin ive done on the matter everyone seems to think it would be headgasket leak and for most people it turned out to be that.
I assume i have the same problem then, new thermostat and fluids. Thermostat is opening and coolant is circulating however fan will not come on unless i short out the plug beside the thermostat or i give direct power from the battery, does this mean its the fan switch that's my problem???
