Need a PCB - keep overheating

[nigelpengelly]

I've got a diesel T25 and the temperature gauge doesn't work.

My van overheats as the fan doesn't kick in and I've had to bypass the sender unit so that I join two wires together by the radiator grill to put the fan on all the time.

The AA said that the PCB is dodgy, which is why the fan won't kick in. So I took the dashboard apart and the PCB has been lashed up with Sellotape.

The bit I need is: PCB/Foil part number 251-919-059/J

I can't track one down anywhere - or could there be something else worng?

Thanks.

Fixing the PCB will just fix the gauge not the fan. If it is just the gauge not working and the rest of the dash works fine you could probably bypass the pcb by adding a wire from the multi plug directly to the terminal on the back of the gauge.

Having done that you will still have the fan to fix. Do a search on the radiator fan sensor as I think I've posted before about it. You can test your sensor by removing the plug and connecting the wires two at a time in the three possible combinations. You should get fan off, fan slow and fan fast. If that is the case your wiring and relay is OK and if the fan is not kicking in when hot then either the sensor is bad or the sensor is wired wrongly.
