all speeds behave the same? If you switch it to 3 it won't come on right away? What about 4?
check the 12V to the switch(ref your manual)
12V goes to the switch in your dash, then through settings 1-3 to the resistor unit on the bottom of the fan motor. speed 4 is 12V direct to the motor. Check your fuse as well(#20?)
There is a chance you have a bad ground on your motor too. To check this, open the cover and remove the wire on the ground pin. attach a wire(alligator clips on both ends works well) to a secure ground(bare metal in the engine - hood hinge, etc. - scrape a clean spot for good contact)
try to turn on the fan, if it works now, bad ground, you may only have to clean the original grounding contacts properly.

ahh thanks something just clicked in.
A while back the fuse blew and it litterally melted a bit of the plastic in the fuse box. I managed to get a new fuse in but its pretty messed up. Thats probably the problem. Is it alot of work to swap in a new fuse box?

BTW: All speeds. The fan would just litterally shut off.
