1996 Bentley Turbo R - Heated Rear Windscreen

Is it automatic?

How can I test if it is working?

Thanks

Yes, it's automatic.

You'll know if it's working by whether or not it clears the screen

In all seriousness, I believe it is set to come on when the car gives the "ICE" warning on the information panel. As I never drive any of my RR/Bs in the winter, I've no idea if mine work either.

so not much use if it's misted up inside, but not very cold outside.....

The rear screens fail when water corrodes the heater matrix where the fine wires enter the glass. New rear screen is the only solution.
Best of luck with it.

But how can you tell for sure if it's working or not?!

Roy,

On my spirit II it, and the heated wing mirrors work when you put it onto demist

If the mirrors clear,and the screen doesn't say goodbye to 1k

And dont take it to autoglas, there is a lot to be moved inside he car. leather wood etc

Go to the Thermometers Direct website, and buy a digital thermometer with a surface probe. Thermometer 100334 will read up to 750C and the surface probe is part number 101536. Cost will be about 50 quid. You might be able to hire one, or you might have a mate with access to one. After all, you'll only need it once. Search e-bay?
Best wishes,
David.

Without any direct experience of this, I would

1. Check for voltage at the inputs to the screen (not sure how tricky these would be to get at or how you'd know the screen was on - ref your earlier comments)

2. Measure the resitance of the screen at the terminals. If its open circuit then there's a problem

In both cases a 10quid meter from Maplins would be enough to do the tests

Thanks for the suggestions guys!
