Hello all my name is Lee and I have a 1998 GTO SR.
I haven’t used the car too much over the last few months but a few weeks ago the rear demister didn’t work - (the little orange light didn’t come when i press the button also). The next time i drove the car it worked, and the next few times it just hasn’t worked at all.
I have replaced the switch unit (with the ECS - which works fine) and has made no difference. I have also checked the fuse (I have the GTO manual and its hard to tell which fuse it is). I have also checked the back window connections and they are connected and look ok.
Any advice on how to fix this please?
