W201 rear window heater switch wiring - plug positions

[Stretch]

G'day Folks,

I've googled

I've FSM'd

I've lost my patience

I've buggered up the order of wiring of the back of the plug on my rear window heater switch - can anyone help?

'Ere's wot eye 'ave



1X red/brown wire
1X multi-coloured black yellow stripy thing with two wires joined to one joint
1X black wire
1X blue wire



Back of the plug looks like this



Two pins on the back of switch are marked with letters "A" and "E" - the other two have meaningless (well to me anyway) numbers on them so I've labeled them "Don't know1" and "Don't know2"

I hates electrickery I does

Did you mean to post in DD? A 6000 rpm w201 diesel seems unlikely.


Just teasing. Sorry I cannot actually help with your "diesel".

A- Blue
E- Black
31- Brown
16- BY/Yl/GN

A = aus or off (blue)
E = ein or on (black)
31 = ground (brown)
15 = power (yel/grn stripe)

Note the operating light is between E and 31 if you are trying to ohm out the switch.

Turning the switch "on" gets you continuity between 15 and E
Turning the switch "off" gets you continuity between 15 and A
There should be some high resistance (several tens of ohms likely) between E and 31 due to the bulb. If its an LED you will only read in one direction.

Thank you very much folks - I did find it in the FSM in the end.

Here's a link to the wiring diagrams

And here's a screen shot showing the diagram



It is called the "defogger" in the FSM

Well I often post here because of the helpful comments!

In development - in development...

After a bit of fiddling I realised there's a clip at the back to be removed

Is this a complete test to see if the switch is good?
