Air con regassed & 3 speed fan brushes replaced, but...

[Billy1mate]

Andrew, I know what you mean, mine was checked before they replaced the brushes & all was ok. I think 2 speed fan might be the way to go but until I can narrow the fault to the relay/pcb Or a fault with the car.

You have a diesel I think. Did the control box from the scrapyard come from a diesel? A petrol control box won't work on your car.

Well Andrew I'm sorry to tell you that that isn't always the case. I have a 3 speed motor and have not suffered any commutator wear. I fitted new brushes some years ago and my original motor is working just fine. I'm not alone; there are other forum members who have also successfully refurbished 3 speed motors.
It all depends on the vigilance of the driver. If failure of the slow speed is detected early, all that will be needed is a couple of inexpensive new brushes. Do nothing, and only then does the risk of more serious damage increase.

I've just had a brain ****. My fan hasn't worked since I bought the car in Feb, ergo the fault must lie with the relays/pcb. Two of the brushes were 1/3rd the length of the others considerably shorter but not completely worn out. Although it could be the car wiring.
