Hi All,

The left hand passenger side of the quick clear heated windscreen on my bmax is not working.
I have read a few posts around this being a common problem that normally results in a new windscreen.
Also checked the wiper problem that could knock against the fitting but this seems ok.

My Bmax is also out of warranty.

So I was wondering if it is worth changing the fuse?
I can see in the manual there is a normal blade fuse for the right handside but not the left, then a larger relay for both left and right handside.
R9 being left.
Please can you tell me if it might be worth changing this to see if it fixes the problem, and if so, where I can source the correct replacement from in the UK, as when searching I only seem to find the normal small blades and not this larger relay?

Many thanks.

Thanks for the reply. And can't believe I was that stupid to not think of swapping the fuses over!
After trying this the left hand side still does not clear, so its not fuse/relay related.

So looks like electrical/element problem that probably means new windscreen. So I think I will stick to the old school scrapper method rather than waste money replacing the whole thing.

Thanks.

I suspect the problem is low battery voltage. The car has a 'power management' system and the combination of cold weather and use of electrical loads may have caused low battery voltage. The object of the system is to try to ensure sufficient battery voltage to start the vehicle. Annoying as it is, I'd rather have a car that will start rather than have a fully functioning heated front screen. A long run or an overnight trickle charge may cure it; personally I'd just wait for the weather to get a bit warmer.
Thanks for this. Could well be it.
As I do not do a lot of mileage, and most of the time the car sits out the front of the house and only does very short trips when in use.

Will try to give it a long run or a charge and see if that helps kick the left side in next time.

But agree with you.....would much rather the car start when required and live without the heated screen!
