The engine fan on my 2001 Octavia 1.8T 4x4 does not come on what ever the engine temperature. I have resorted to turning the heating up fill  when in stationary traffic which drops the water temperature but is only a temporary solution. I have taken the plug off the water temperature sensor towards the bottom of the rad and get 12v on the bottom right spade  but when I connect the tp the to  spade the slow fan does not come on. When I connect to two lower spades together with the ignition on I do not get the high speed fan on either. 

 

Is there a fan relay or anything else in between the   fan sensor plug and the  actual fan that could cause the issue.

 

Mu next action will be to put 12v directly onto the fan and check if it operates. 

 

Any advise would be appreciated.

 

 

Welcome.

 

Well worth trying to see if you can get the fan going manually, also the coolant temperature sensors are prone to failing, what colour is the top of your sensor?

There is a fan controller at the front of the engine bay down below the battery tray. Just follow the fan cables back until you reach the controller. Have you checked the fuses on top of the battery?

I have checked the fuses over the battery cover so will check the fan motor operates witha dirrct 12v source and then work back to the controller under the battery.

 

Thanks for your help
