Yes, but what is likely to go wrong with the blowers? I would suggest it's either the bearings or th windings (probably the insulation breaking down in the latter case). The bearings are likely to be ball races nad will be standard sizes. I have never found a custom ball race in a computer. So you extract the old onws, measure internal and external diameters nad the thickness and go to the local bearing stockists. If they're bush bearings rather than ball races, you can make replacements ina good home workshop. The windings could be more of a problem. Yes, you can rewind motors, but in a lot of small blowers, the stator laminations are spot-welded to the casing, adter the thing was wound/ Rewindign looks to be a very fiddly job, but I guess it's possible. -tony
