Should the rear defrost button stay pressed in when on just like the hazard button does? Or, does it stay on but pop back out?
Anyone?
Thank you

Just trying to figure out if my switch is broken or if something else is wrong with my defrost.

Some cars have a time delay button. You push it in, but it doesn't stay in. A relay in the switch clicks and says on for ~15 min.

Thanks so far everyone. Mine does light up orange and does not stay in. I just need a condensational day to see if it's working.

Yeah it will stay in and defrost will run until you push it again to turn it off.
I don't think there is much juice going to it though cause even with a 45min drive if the snow won't all melt off my back window if there is more than a dusting.

Actually it uses a lot of juice. The switch to the non time delay button happened in 2003 as I recall.

There are two types of switches. The 10 minute timed and the non-timed.
My mk3 is non-timed. My 2000 is timed, my 2005 is non-timed.
I prefer the non-timed. I'd rather leave it on all winter.

I think the rear glass heater uses something like 20 amps of power. That's nearly 250 watts.

Some owners advocate using the defrost on cold mornings, even if you don't need it, to speed warm up time...the amp draw is enough to load the engine and bring it up to temp quicker.

For that kind of power draw it sure doesn't work well.

Heh you're right on that note.

Works fine on my 99.5

They work OK, but compared to my mk3 or another car....no contest.
Takes me usually two cycles to clear light fog.
