Rear windscreen heater
The heater/demister on my rear windscreen does not seem to be working have checked fuse and cannot see any damage in element, light comes on in dash when its switched on.
Is there anything else i can look in to?

It's HIGHLY unlikely that element damage would cause the whole thing to stop at the same time, it's more usual for one, or two of the lines to fail.
First, check the connections at either side of the screen. Have a look for evidence of oxidation of the contacts due to moisture ingress. Look for any signs of detached/damaged wiring.
Next, use a multimeter to check that you have 12V on one side, when it's switched on, and a decent earth on the other, when it's off.
My guess would be a faulty relay, (best guess), or a wiring break, (less likely).
Sorry, I'm not sure where the relay is located........
