p reg vauxhall astra. The first 2 positions on the heater blower switch stopped working but positions 3 & 4 still worked. now pos 3 has also packed up, only 4 still works. I'm guessing that each position has a different value resistor across the supply to the fan, so to fix it i need to replace the burnt out resistors.
Am i guessing right or is a different system being used.
Any help appreciated.
Thankyou both for your help. That's me busy this weekend !

if you remove the pollen filter you will see it held in by one screw.

Yes you are correct you need to replace the heater resistor. Not 100% sure but i think its located on the heater fan under the wiper panel on that year.
