Heater unit got me stumped... HELP!!
The story so far...
(2000MY 2.0 GTV Phase2)
No heater controls working (just the rear demister but that not the issue)
1/ fan works when 12v across it (but nothing on a/c panel)
2/ control unit replaced
3/ replacement speed resistor pack replaced with known good item
4/ 30a fuse under bonnet supply good
5/ all fuses under steering wheel good (fuse panel looks ok at the back)
6/ visual inspection on all plugs and wires
7/ 12v supply at large white plug (red wire) & 12v supply with ign on (orange wire) good earth
8/ fresh (30a fused) power supply by-passing car wiring to heater cable (still nothing)
9/ earth checked in loom at heater ok
10/ still nothing on a/c control panel.....
Am I missing something obvious, and any other things to check please!
(its driving me nuts...)
