Alright,

I thought I'd give the above a go using the write up in the articles section, but when i connect a wire from the hazzards to the heater switch, the heater switch lights up as if its on even though it's not (if that makes any sense?)

Just wondering if anyone has had the same problem & knows how to sort it?

Thanks

Stu

what the article doesn't say is, you need to swap the demist switch with a spare hazard switch and swap the face of the buttons.

and also attach a second wire. then it will work.

the demist switch is dimly illuminated in the dark just like the hazard switch. And bright when switched on.

The article was written based on using a modified demister switch rather than a hazard switch with the cover swapped. It's 100% accurate if using a correctly modified switch. It was also written before it was found that you can swap the covers over.

So I have now done this mod to mine, and it lights up, but seems dim compared to the rear wash wipe and hazard switches. Any ideas?
