Is anyone able to shed any light on this for me?
The auxiliary fan (the electric one) does not run on high speed, I am activating this by shorting the connections at the thermostat switch, I got a second fan, but this had the same issue.
So I put 12 volts in to the fan & it now runs at both high & low speeds.
Put back in the car & still only running at low speed, so now I know it's not the fan.
I have also replaced (what I believe to be) the high speed relay, but still no joy.
There are voltages everywhere I'd expect to see them, but no high speed fan.
Would anyone have the part numbers for the high & low speed relays?
And also, can the relays be swapped round (so in a perfect world, my low speed would not work, but high would).
Apologies for the long post, but with summer looking like it is here, the last thing I want is a car overheating again.
Thanks in advance.
