TD4 fan runs all the time....Normal?

Hello All,

As title says, the fan runs on a slow speed from start up on my TD4, and I'm not sure it should.

It runs with or without the aircon on, and its both fans.

If this isn't normal, are there any common fauts that cause this?

Thanks in advance!

Hello , its not normal ive not heard or seen my fans working yet ! could be faulty temp sensor or relay

have you got it set to windscrean try the heater controls off because if it is in this position they will be on with the blower on number 1 but it is not normal if it is not switched on

Thank you! That's the reason why!

Why does the fan run with the heater fan running though? I'd understand if the aircon was on.

Thanks again!

So am I.

If the heater fan is on and set to windscreen the aircon/cooling fan runs on slow.

Weird!
