Heater fan problems

Mornin' all, just a a quick couple of questions.

My heater fan, doesn't work on any settings now, i've checked the fuse and unfortunately its not anything as simple as that.

I am intending to change this bad boy as its cheap - http://cgi.ebay.co.uk/VW-GOLF-MK1-MK2-GTI-HEATER-BLOWER-SWITCH-FAN-C325_W0QQitemZ190283094931QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item2c4dc19b93&_trksid=p3286.c0.m14
Could this be the most likely culprit?

If that fails then I will replace the actual fan unit but would like to know if the fan unit from a mk3 Golf will fit and work as i have one lying around?

Thanks

If your handy wth a m/m check for voltage at the switch, if there is bridge it out, if that doesnt work switch it on and check for a voltage at the fan if there is and the earth for the fan is good then replace fan.

Thanks for that, i'll get my electrical tester out and check.

Right, looks i'm going to have to replace the heater fan. Does anyone know if the fan used in the mk3 can be used?! if so, it would save me buying one!

Thanking you muchly in advance

I wouldn't have thought so. I would also advise steering clear of 2nd hand ones too as they're all pretty ropey by now.

mk3 one is a completly different shape, corrado & passat ones fit i believe?  Not 100% on that. just need to swap the 4 speed fan resistor for a MK2 3 speed one, or fit the 4 speed loom & switch as well like I did
