copter steve,
Appreciate your reply. Our mechanics did a battery charge test and say the battery is charging correctly. But as I said they also tell me there is no power being delivered to the fuse block or the blower moter, or the dash mounted fan control.
I am going to try and locate the resistor block and have a look at that, but I still suspect the alternator right now.
Have a small plug-in the cigar lighter heater on the way for a tempory heat solution, just really need to keep the window clear on the cold morning drives.
