    Hi Stuart. Ive been pipped to the post again, I will have to start finishing work early to beat this lot, But as David say's it is nearly always the heater valve on the bulkhead that causes this problem, all we do is put a voltmeter across the 2 wires going to the valve and if it fluctuates as you turn the switch to hot and cold it is usually the valve that is the problem. we have also had one in that would not turn off hot, that one turned out to be bad soldered joints on the control panel. best thing is buy a spare valve and just plug it in and watch it as someone turns it from hot to cold, I think it needs the engine running to do this.?? p.s if you buy the valve and don't use it, it will come in at a later date for KA.s, Fiesta's, Puma's etc.
