Hi new to this as ive only had my t5 a month ,, got a problem with fan staying on .?. Its the smaller one on the drivers side not sure if its the air con or heater fan , but battery is dead any help would be greatly appreciated, cheers kevin
There's a well-known common fault with the temp sensor on the front bumper failing or getting disconnected, but that won't cause the fan to stay on with the ignition off. If the fan really is on all the time I would suspect a relay fault - it's ~probably~ one of the relays in the E-box in the engine compartment, but I'm afraid I don't have a relay allocation diagram for a T5 of that age.
