Aussie subi fan

Thanks for the help guys, I got stuck into it and pulled the dash out. The problem ended up being twofold - the thread on the heater dial had stripped and the whole switch moved rather thatn the wheel on the rear. I fixed that by adding a washer and then the locking nut. The ither problem was the control gate under the bonnet near the firewall where 4 heater hoses enter. The gate was very stiff. I replaced that and bugger me, the car has hot air!!!! Cheers and thanks.......

Thanks Callum, I checked the vacuum hose under the bonnet and it sucks fine! Not sure about diaphrams but thought I might pull out the dash and see whats what. Will let you all know when I find out. Stuart

Hi, I have a 1986 Brumby utility and the heater wont work. When I adjust the temp dial to heat nothing other than cool air comes out. I have heard that it may be the switch tap on the heater hoses under the bonnet, any help would be great. Thanks in advance. Sorry but I also live in Australia where the winter here now only gets to about 8 degrees celcius. The car had been sitting for about 5 years before I got it and started to fix it up.
