Heater blower only working on 3

[gary_126]

Hi, started my nova up yesterday and let it get up to temperature, put the fan/blowers on and its only working on position 3.

Any ideas what the problem is? Ive heard of newer vaxhalls needing a resistor replaced in the controller, but not of any common issues with nova blowers.

It worked on 1 and 3 the last time i tried it, about 6 weeks ago (the cars garaged, and has been since last october)

rheostat on the motor has failed

^ The little green resistor on the heater blower? I think you can get them new from Vauxhall but it's quite expensive as it comes with the wiring...

Oh right, anybody know if an aftermarket resistor of the same resistance value/s is available?

quicker, easier and cheaper to fit a second hand motor unit

Only problem with a second hand motor for me is it would have to be posted, and therefor it could quite easilly be a dud aswell :(
