Yeah, that's basically what needs doing. I also change the reisistor value to give the correct brightness.

Aparently you can just swap the switch cover from a heated rear window switch into a hazard switch and it works. Never tried it like this though.

Thats not what i need, The Actual rear heated Screen Switch internals need bits adding to it from the inside of the hazard switch. But i dont know which bits.....

The Hazard Switch has 8 Connetors on the back, the heated screen switch has 4.

yes but the 4 terminals on the heater switch is the same layout as the 4 on the hazard switch.
The others just are not used

So if the swap has made is the extra wire needed from the tech article or it will work without it

[oze30]

Hmm.. slight problem. My heated switch plug has 3 wires/pins.. where did my 4th one go???

Yes, as this is the "Dimmed" supply for the bulb.

the covers arenԚ´t actually the same or the componetry inside is different?

[kam-325i]

Right, here goes.

Switch covers are swappable

The extra wire is needed to supply the voltage to the switch for the dimmed light.

[johnono]

good man for checkin that out ;)

You will have to come round my house Keith and show me how its done!
What parts do I need to get?

[kam-325i]

Atleast a hazard switch to butcher, but a spare heated screen one aswell, just in case, also a spare spade connector for the heated screen.

Someone please explain this modification to me?

My defroster switch already lights up, and dims with the dash lights.

So does the one in my girlfriends 89 325i...

As standard, the rear heated screen switch is not illumminated when you switch on the lights, only when the switch is in the "On" position.

Not sure if this happens on US models.

It would have to be a weekend......
