Tore aux fan apart; brushes look fried...

[The Warden]

Well, while doing other things on my car (ripping out old car phone, digging for coax cable, re-wiring the fogs), I decided to remove and disassemble the auxiliary electric radiator fan. First, it's amazing to see all the stuff that can hide behind that fan; I don't think I was getting any flow whatsoever. Maybe the car'll cool a bit better now.

Second, the front bearing was fried...metal particles all over the place. Not really surprised.

Third, it looks like the housing around the contact brushes on the fan motor melted. I'm guessing they overheated as a result of the bearing dying and no one disconnecting power before I pulled the fuse. The brushes don't spring in and out like they did on the voltage regulator, but I don't know if they're not supposed to or if they're bonded enough to the plastic housing that it's beyond repair.

Is there a way to replace the brushes? Or is it too far gone? Maybe it's scour-the-junkyards time...

Thanks in advance!
