Well there is me thinking I've passed the 100k mark in the Ph3 and all is going well. That is until this week when the heater blower has stopped working. I've been reading through the site and others for fixes but as of yet it's still not working.

So far I have checked the fuses and all are OK and swapped all the green relays around to check one of those hasnt died (light green ones). I've checked the voltage going to the motor and that is OK. There is a three pin plug on my motor with a thick Red, thin blue and red, and thick Black. At the red I have 14 volts so all good. The black is earth and I have that. The blue I get varying volts from 1 - 4 I think it was depending what I have my fan speed dial set at.

At the motor terminals I have 10-12volts on the positive terminal depending on fan speed dial position. Oddly it starts at 11 then dips to 10 and the rises to 12. On the negative terminal of the motor I thought this would have continuity with earth but it doesnt?

I've put 12 volts through the motor direct and the fan spins fine.

I've read about a resistor pack so I removed the scuttle etc and air feed but I could not find said resistor pack. Is this in a different place on a phase 3?

I'm now stumped at what I check next. Any help would be much appreciated

Cheers
Paul

Thanks for the reply Grumpychef.

I went back out to the car and checked all the voltages again and still had 12v across the motor terminals. This had to mean the motor should be spinning!

So I stripped the motor from the unit again and on closer inspection I could see that one of the brush housings had come loose and the brush was not at the correct angle. This morning when the motor spun I assume I must have made the brush make a good enough connection when looking over the motor.

Anyway £15 later and I have a heater blower that is fully functional again No idea if that is a good price for a 2nd hand unit, I should have done my research before heading to the local scrap yard.
