Hi lads, after years of trouble free motoring I’ve had to problems develop over the past few weeks, one with the Tacho is sorted but another problem I have is with the heater controls 
It only blows hot air and the fan blower switch works erratically, position 2 is off, 1 is full on, 3 just low etc.
I replaced the blower and resistor yesterday (at the advice of a local auto sparks) but it’s still doing the same thing.
The fault on the dash is mid146 sid250 fmi9
Is is the switch panel that’s faulty? I’ve the dash all out and would rather get it sorted before I put it back.
Cheers
John
Just in case it helps you out, got the following off the net.
Mid146 = cab climate control.
Sid250 = sae j1708/j1587 data link.
Fmi9 = abnormal update rate.
Time to get shut fm tipper ,once the probs start they dont stop buddy
