Vitara - heater fan stopped

[Apm83]

Just hoping to pick the minds of some wiser than me - this morning the heater fan stopped blowing in the old girl - 1995 Vitara..... checked the fuse, but not that.
Not real useful with the roar coming up and me wanting to disappear into the muddy bush

Do they have some form of replaceable resistor - where should I be looking next?

cheers in advance.

They have a resistor pack down by fan unit (behind glovebox) it is about $50 for new resistor pack or could be switch mine has stopped working on 1 and 2 you can replace that or buy a dc motor speed control find a place to mount and re run wiring they are $25 +shipping http://www.surplustronics.co.nz/products/6177-dc-motor-speed-control-controller-governor-12v-30v-
