If you are certain you have a two speed fan with a resistor then one option is to contact member Jules or DMGRS on here for a resister upgrade kit. on a 2005 car its a bumper off job.

Have a look through the grille and somewhere on the right on the fan mount you should see a silver or gold resistor. It's about 3 inches long and is the only obviously metal bit in there with all that plastic. New ones are easily obtained from DMGRS or eBay, but make sure you get a gold one as the silver ones are the cause of your problem.

If you've got a Mk1 then you can get at what you need by just popping off the grille and one of the little plastic shrouds behind it. Whip off the old resistor, remembering where the wires go and re-fit in reverse order. If you've got a Mk2 then I think it'll be a bumper-off job.
