Heated Windscreen Switching Problem

[BrummyGit]

My 2005 Mk2 Galaxy has developed a switching problem with the heated screen.

 

Almost every time I start the car the heated front screen comes on and goes off a short time later. When on or off the push switch on the dash only actually switches its state maybe 1 time in 10 pushes.

 

I have swapped the relay R23 labelled 100 today but this seems to be a simple switching relay and hasn't made a difference. Can anyone help with this problem or point to either a wiring diagram or the location of the timer unit which could well be the fault.

 

Thanks

change the button (switch)

Thanks - do you know if that's where the timer module is?

WD 40 The switch. It could be sticking internally.

Module is probably part of the central junction box.
