Mk4 Golf defroster switch illumination colour?

[VAG Fan]

Quick question to Golf 4 drivers. Can someone check in their Golf 4 what is the colour of the rear window defroster switch illumination when one switches the car's lights ON, but the defroster is still OFF?

I seem to remember that this night-time illumination of my Golf 4's rear window defroster switch used to be red, like everything else. Lately I've noticed it is a medium yellow, which changes to bright yellow when I engage the switch. I seem to remember that it used to be the standard red, and only changed to yellow when switching it on. I find the medium yellow illumination distracting.

But I may be confusing it with my Audi, which changed from red to yellow when switching on.

You're confused. Yellow it is.

A few weeks ago, I de-mothballed my old 500 SE and used it for a few days. That's probably when my brain conbombulated itself. The switch-over from red to yellow in the Audi was what I had seen and internalised for 15 years.

Back in the Golf, to add to the confusion, the Mk4 aircon switches do exactly the same red-yellow-switch. So of course now I kept on noticing the difference on the defroster switch after having noticed it the first time. Thanks for disconbombulating me.

Thread resurrection for feedback.

Ha, I wasn't confused after all.

Yellow it is not! It should indeed be red, and only change to yellow once you switch on the actual defroster. Just like I thought I remembered it.
If it's a dim yellow, even when switched off, this indicates a broken earth connection, and the defroster doesn't actually work.
