After my recent electrical shennigans (Battery drain leading to new keys etc) I have found that I have another problem.
My Max aircon button no longer works. The climate control works fine both hot and cold and the blower motor works fine too but the max button which worked fine in the summer has stopped working, no light comes on at all and there is no difference in the fan speed either.
I have had a look at the fuses and they all look fine. Also if I use the residual heat function (IE engine off key position one and press max) the light comes on and the function works, but when I try it when the engine is on absolutely nothing.
Obviously I have a fair few months (till we get the one day a year when the Max function is needed) to diagnose this lol, but I would rather try and diagnose it myself rather than spending any more of the wifes shoe fund on Big Bertha.
As always any help is greatly appreciated.
