Selective windscreen demister

9 posts in this topic

Hi,

I hope you all had a great Xmas.

Today's little problem is that I seem to have only half of the electric windscreen demister working! ( passenger/nearside ) Is this possible, common, rare, unlikey or should I change my psychiatrist? Any clues would be greatly appreciated.

I wish you all a fantastic New Year.

Regards,

Probably one of the element wires in the screen is broken. Only fix is a new screen, not cheap

Hello again,

Thanks for the replies; jam, I seem to be in the same boat as you, I've found both fuses and they seem to be OK, I've bought what I think is a replacement from Motorworld but I haven't tried to fit it yet, 40 amp but the case looks a bit big. If replacing the fuse doesn't work then it may be that SY is going to be right!! What a New Year's pressy ?

I'll let you know how I get on.

Regards,

The windscreen has 2 constant wire element running through the glass. One on the left side one on the right. It gets warm by power flowing through it. If that one wire gets even a tiny crack in it it cant conduct the power therefore it doesnt get warm and doesnt work. The other side though is a seperate wire so will still work. Basic physics really buddy

Yep and guaranteed its close to the middle of the screen where the 3 lines are missed???

I'm not taking wild guesses here mate, this is whats wrong with it, 100% certain
