Default cooling Fan

Asking for a friend.

I know this may have been asked many times before but I cant see anything with the same symptoms

135 diesel 2004 From cold or hot as soon as you switch the ignition on the cooling fan starts running, when you switch the ignition of it will continue to run on for a few seconds before stopping.

So any ideas as to the cause ie stuck relay, wiring in the wheel arch etc.

Hi John.
Your friends car when the ignition is set to II from cold or hot, is the A/C switched to the off position ?

If not and is on auto it will start right away, and maybe run for a few seconds after turning off.

check and report back

Hello Steve , That was my first thought, But no the AC is OFF..Also when you turn it off and take the key out all the ignition lights stay on and the fan runs for maybe 15/20 seconds, Then it all shuts down, The fan runs all the time even when driving. I dont know if it makes a difference but it is an Auto..Gear Box.

Hi John.
Sounds like it could have PCB trouble, have you tried pressing Econ to see if it makes any difference, it needs sorting other wise the brushes will wear down rapidly, you and your friend, are the right place, drop French Mike a PM or contact him to have a look at the PCB.

Hello again Steve,

OK, So where is the PCB located? as there does not appear to have the Box that was next to my Fan before I swapped it over. Not sure, Currently have the front off and cant see a Box where I thought there should be one I originally thought it could be a relay stuck. I suppose I could try another fan unit and see if that alters any thing..


John

Hi John.
The PCB will be inside the black control box attached to the fan top right hand corner.

Sometimes people do move the control box into the engine bay so also take a look there around the battery at the front is popular.
