Radiator Fan not powering up on DC2

[kerim]

There doesnt seem to be any power coming to the fuse uinder the dash, fun works when connected to power supply, what could the problem be, it is an aftermarket slim fan, there is no power coming to the connector that connects on to the fan connection, what could the problem be?

anyone experience this before

thanks

Thermostat?

If the fan is working when you are throwing direct power to it, and the fuse is not blown.. most likely your fan switch has had it.

as above

but the thing is there is no power coming to the fuse under the dash and its not blown

with out looking at the schematic I would asume that its ment to have power at the fues. it might only get power once the thermo switch has changed state and the thermofan relay has engaged.

a quick ( cheat ) test is to remove the fan relay and bridge the contacts and the fan shoudl kick in.

another good test is to undo the thermofan switch connector and bridge its contacts, then if the fan spins thats your problem.

im guessing you have a EJ8 ???

Hey i got the same problem as well, try bridging the fan relay but nothing turns on.

What can be the problem and where is the thermofan switch connector located?

[Phuong1987]

Sorry bro, hope im not taking over the thread

[ECU-MAN]

DC2 should be the same.

which conacts of the relay did you bridge.

the thermofan switch is on the thermostate housing

[kerim]

DC2 should be the same.

done that, and fan worked, so the only thing that it can be is the switch, will change that and see how we go

[Phuong1987]

which conacts of the relay did you bridge.

the thermofan switch is on the thermostate housing

the one connects to the engine

[ECU-MAN]

thats not the relay, thats the thermofan swich, if you got it right.

take a photo of what you bridged.

[Phuong1987]

Yeah thats what i bridge, cos i tried it on my brothers car and it and the fan was working and mine doesn't. What does this mean

[ECU-MAN]

bridge the relay as I have mentioned.

note; the relay is not the thermo fan switch. you will find it in the under hood fues box.

[Phuong1987]

Ok, what happens if i bridge the relay and the fan doesnt work?

theres 4 pins, which one do i bridge

The relay may be faulty and need replacing, Check ALL fuses under dash and also ALL fuses under bonnet next to battery.
