All,
ive just completed this fix on my GU and thought id post up some photos to show how easy it is.
Remove ~8 screws from around the glovebox and remove the glovebox.
then disconnect the plug for the fan resistor
then remove 2 screws and pull the resistor out of the fan module.
photo of location of resistor
then on the resistor check to see if there is a circuit between the right pin and any of the other pins (as shown below). If yours is like mine there is no circuit and the fusible link would be corroded.
Carefully scrape away the dark coloured coating till you get to shiny metal either side of where the fusible link should be and solder a piece of wire across the gap.
Then check if the fan works.
Note that the resistor gets cooled by the fan when its installed in the car, so either only turn the fan of for 5 second max or completely install the resistor in the fan module before testing. Otherwise you could overheat the resistor.
