Heater/Aircon Fan working intermittently

[Billrw136]

I have a Disco 3 TDV6S - 7 years old - in the last week the fan shuts itself off after a minute or so - not every journey - if I then trying turning it on again, it will usually work again for similar amount of time then shut down again.

Any one got any ideas??

Makes no difference if aircon is on or off.

Cheers

Bill

You might like to swap the fan relay for another in case its switching contacts are burnt.
