I have a noisy aircon fan. Squeek is proportional to fan speed, and is noisier under braking.
Sounds like the bearings in the fan are shot.
a) where / how much for a new fan?
b) how big a ball ache is it to replace? I've got the "replaced an E46 hedgehog" medal, but hoping its easier than that!
If someone could post some snapshots from TIS that would be great - my copy no longer works on 64 bit Windows
