Voetverwarming defect

Hallo

Mijn Cooper S, bj 2002 heeft automatische airco. Wanneer ik op de knop voetverwarming druk komt de lucht aan de voorruit eruit en niets aan de voeten, bij de andere knoppen werkt alles correct.

alvast dank

Je kunt een zelf-test met de airco doen, waarbij je ook eventuele foutcodes te zien krijgt:

This is an on board diagnostic function of the IHKA (BMW geek speak for climate control) that provides three test modes. Mode 1:Read fault memory; Mode2:Calibration run (this is what I refered to in my original post); Mode3: Manual check of functions.

On my 2002 Cooper the diagnostic function can be accesed by simultaneously pressing the OFF button and the blower PLUS switch for approximately 2-3 seconds with the ing switch in position 2.

The display panel will show a single streamer bar for Mode 1 - read fault memory. Keep pressing the OFF button to scroll through all the modes; a second and third streamer bar respectively will appear to indicate the mode.

To enter a particular Mode, press the AUTO button when that Mode is displayed.

To exit turn off the ignition switch.

If no faults are present 00 is displayed; otherwise a fault code will appear.
Mode 2 will perform a calibration run of the servo motors responsible for actuation the flaps in the HVAC distribution box below the dashboard; if you listen carefully you can hear the flaps moving. This is useful to diagnose a problem where ther is no air flow to the footwell (common failure on Cooper). If the system is able to cycle the servos through full range of motion with no errors, the motor and electronics are fine. keep in mind that the feedback sensors are located inside the servo. So if the test passed it means the motor moved...but the flap may not have moved because the linkage is broken. The fix is to remove the entire dash and replace the broken flap.

There is a way to perform this diagnostic on all vehicles with climate control....without the use of expensive Dealer only tool. the diagnostics is built into the dash..all you need is your fingers.

pardon the long winded post and I hope this helps. Please advise of any further questions.

Waarschijnlijk bediening stangetje van de kachel los geschoten.

Hallo
Heb dat probleempje ook nu.. De voetverwarming werkt niet in m'n Cooper S 2003..
Lucht komt alleen naar de voorruit, en de rest werkt gewoon prima. Heb je dit probleempje opgelost?
Zoja kan ik weten hoe:P

Bedankt alvast:)
