Heater fan intermittant.

[bandit44]

The heater/ac fan in my series 2 vt has decided to play its own game. Every other day it decides it does'nt want to switch on, if you button up to max it works fine. If you don't touch it and let it just sit on any speed it will eventually come on, could take 10 mins, could take 1/2 hour. Is this a problem anybody else has had? and does anybody have a fix? Thanks

I had the same problem,turned out to be a relay.To check,lower the fuse panel under the steering wheel and locate the blower fan relay and swap it with the rear window demist relay which is located next to it and hopefully the fan will work.I bought the relay from holden for $19.00.
