When The weather gets a bit better and i can move it nearer i will investigate further. I have taken a quick look and tried to eliminate the easiest thing first.
Checking the + means taking out the fuse box and checking the back of it and checking the connections on the switch...

Hi,
Any update on your heater issue?
I have the same issue but haven't looked into it yet.
Got to get my DMM out and do some probing around.
Only the middle element heats up on my window.  |

If one element is heating up then looks like power is getting to the screen. At a guess the elements in the rear screen are damaged. You can get small pots of conductive paint to repair heated rear screen (difficult bit is probing with the multi meter to find the breaks).
All the best
Keith

What a stroke of luck!
Had a rainy day the other day and the whole car was like a sauna.
Could only see through the windscreen due to the heater there.
Parking in my rented place was a little difficult between 2 Hilux pick ups with about 18 inches either side!

Probing with a multi meter will not find the breaks, the element is one big cuircit. Weather it has a break the meter will still bleep unless all the elements are broken.

You can probe fore resistance though, which will jump after the break.

I was probing around with my DMM last week.
I found that the lines with the mat grey material on them seems to be the conductive material.
I was getting 12 volts on these areas on the right hand side.
Where this has rubbed off leaving the dirty yellow underneath film I was getting no reading.
So I guess there is no way of fixing this.
Next week I'm getting UV film put on the windows anyway so it's all going to be covered up.
