The big plstic Circular part with all the wires fitted under the passengers carpet is secured on by 3 6mm bolts. Remove these 3 bolts and pull the blower out. There is 1 tex screw in the top of the plastic. When removed the whole plastic surround comes off. Now remove 2 6mm bolts and the resistor pack comes off. Job Done, Roughly 10 minutes. Hope this helps...
