Sorry for posting yet another post about this.
My heater/blower seems to have a mind of its own, blows at min then max then min then max, sometimes changes within seconds or can take a few minutes to change.
Changing temp up or down does nothing. Ive worked out from reading on your site that its probably the Final stage resistor that needs replacing (am i right)
How can i find out which part number to buy before i take out the broken one, also anyone know the best place to buy one, please.
Any help would be great.
