3 Speed Fan - Rotten luck? - Page 2

*Update.

Had this checked out today, the fan DOES work through using the Aircon but is not triggered by the engine temp. So it looks like the control Module?

For now I can force the fan on by using aircon, if it gets hot.

Anyone had this before?

check the temp on the dash using the IPK diagnostics at see what the actual temperature is rather then relying on the guage

Hi Greeners, yes I do. I always run the car with the actual coolant temp showing using the diagnostic tool

Greeners · 22nd July 2015, 18:21

what temperature does it get up to ?

Not just recently either, I fitted one to my last car probably around 5-6 years ago and it only lasted 18 months, or to be precise, 18 months after I fitted it I noticed it was no longer working

The replacement however continued providing sterling service until I sold the car a couple of months ago

Driving along it stays around 92, then slower moving traffic on a hot day around 98-102

With the fan it stays in the late 80s.

Is the fan is running at 102° and does it successfully reduce the temperature to 96°?

No, the fan didn't kick in itself at 102. The fan only works if I stick the aircon on LO (not ECON) then it works. So it seems my problem is the control box/module. But I understand that is part of the fan set up behind the bumper.

Stephen; can you repeat the test using the windscreen demist button when the engine is cold. Using 'Auto' doesn't guarantee that the air con. is activated as you've found out.

Will do Simon.

So when the engine is cold I just switch on the ignition and press the demist button? Sure I done this on Monday but nothing happen (with the fan).
