Anyone know about them played with one? I can’t find a decent wiring diagram. I have a good earth to the motor. If you remove the 3 pin plug on the resistor it has 12 volts on each pin depending what speed setting your on. So I guess that’s the interior wiring and switch ok. There is a single wire the other end of the resistor. I’m guessing that’s the signal through the resistor to power the motor. If I un plug that terminal and power prob it the motor dose not work. Am I right in saying the blower motor is the fault?

 

I’ve never played with a sapphire heater blower but I do get paid for mucking about with electrical stuff and if you are directly and correctly powering the the motor without any of the controls then it has to be the motor. I would try giving it a clean. Does it turn freely?

 

Yeah turns freely. The small terminal on the resistor has to be the live to the motor. The 3 pin plug must be the 12v supply to the motor via the resistor to regulate speed. Just nice to see a diagram or have someone say they had the same issue. Think I’ll order a motor

 

i had issues when i swapped a motor from a granada, it had more wires on it and so it wouldn't work at all
so make sure you don't get the wrong one

 

im pretty sure you can buy them new from Germany .they are a lot quieter and better than the old ford ones andy

 

I’ll take a look into that.
