Evening folks.
Ever since I got the MK5 GTI the demister has never worked. Was fixed under warranty, sh!te job (just bypassed the relay and used a button switch). I know it's not the control unit (i.e. heater control panel). Is there anywhere I can get a copy of the wiring diagram for said system. I wanna fix it properly so when I press the demister button, it lights up orange and actually works!!.
The button doesn't do anything on the heater control panel, no light relay doesn't click etc.
Thanks
Paul
