I recently changed my none working 3 speed fan to a 2 speed fan, having finshed the job, today i decided to have a look at the bushes inside the motor of the 3 speed fan i had taken off and boy did i get one big surprise the plate inside had disintergrated, also 3 of the springs which work the bushes as they wear down had become so week they no longer pushed the carbon bushes forward to contact the motor no wonder it failed this must have been like this since i purchased the car as i have only done about 800miles in the car since i brought it in Oct 2010.
I wonder how many other cars out there are in this state unknown to the owner if they are not this bad and only the springs have failed that to would stop the motor from working surely.
Note how this as rotted away pic 3
pics 6/7 is the other side also rotting away.
Pic 8 shows the bushes and their springs note from left to right how the first one as no spring must have disintergrated or fell out, second and third springs failing to push the bush forward fourth is still strong and working as it should.
pic 9 shows the bushes have all worn the same length approx so it must have been the springs that failed burning out the motor thus helping to rot the plate on which they fit.
All bushes are approx the same but to be 100% from left to right are 18mm 19mm 21mm 21mm so i would think the 18mm would have been the low speed bush yes ?
What are the opinions of those in the know about this please. If any cheers Arctic.
