Thermo fan issue

[BLK_20v]

Just wondering if anyone can help out with my electrical issue of my thermo fan not working...

Have done the following troubleshooting.

* Checked relay terminals for 12v ign power
* Checked A/c pressure switch is connected
* Checked continuity between temp switch and earth to relay
* Checked thermofan works - (bridged power on relay and on comes the fan)

My understanding is if I unplug the temp switch the fan should come on.

When i plug the temp switch in, I can hear the relay click but the fan doesn't turn on when I unplug it. Nor does it come on when the car is getting warm.

Any tips / help would be greatly appreciated

You bridge power on the relay and it worked.. I would say your relay coil is switching but not properly, try a new one

^ ^ or check your relay is wired correctly
