Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

Tried to change the bulb today, but it did not help.

Measured with a voltmeter, and there was nothing between the + and -.

Tried to measure the red wire to earth, and got 12 volts.

Someone with any suggestions?

I did the very same check on my wife's Corsa that we bought on Saturday with the same result. I won't have time to investigate further until the weekend but I reckon the lamp is probably switched on the earth and not on the live.
