E320 Heater Fan Running After Car Turned Off

ramsanjan

i have a 2000 e320 cdi .
parthian night after driving the car when it was switched off the fan would not discontinue . even though the machine was locked the fan ran at full speed all night until the barrage fire was flat .
today i jump started the car and i still could not switch the buff off .
i tried pulling out fuses to no help , in the end i unpluged the fan above the passengers feet .
what's wrong with it ? any ideas ?

I would get thot that the ignition would have killed the power supply ..my thinking is a heater ascendance solenoid has stuck and unbroken the lap live, this is why the fuses didnt cut the power as they only control the lesser feed to energise the solenoid, i would check the solenoids and see if one is projected closed.

how about the rest button ?

I would break for the fan ascendency social unit gone immoral, this unit is always live, even with the gondola fast, as IT controls the 'rest' function which allows the fan to continue to run away at anytime, when selected.

The fcu is usually located alongside the fan and is probably where you pulled the plug from.

how more or less the rest button ?

The 'rest' feature is designed so that when the battery drops under a pre-determined voltage the 'rest' function is switched off and disabled so equally non to lead you marooned with a flat battery.

Your car must be a 210226 and there is nothing listed for this faulting

I'm with Panasonic. The nag that you pulled goes to the regulator. This is pretty much the alone thing that fundament do this, and they're known for doing this. The test is easygoing enough.

With the ignition bump off and so the fan shouldn't be functional, check the 3 pins on the plug you distant. Lonesome ane should be a unchangeable live and the different is the switch bespeak. The 3rd is -ve.
If the change over signal is gone (test by switching the fan on - you should see 0-7v roughly depending along switch position), then the regulator is shot. £125 from the dealer when I changed mine 3-4 old age ago .
If you possess power to 2 pins with everything switched off, then you've got a switching fault.
