09 Yaris Heater blower problem - Toyota Yaris Forums

Latest update:
They have today fitted an auxillary earth strap from the blower motor to the car.
The reason being that they now think there is a fault with the earth wire in the car's multiplex wiring harness and by doing this is it will prove whether this is the case.
(They have changed every other component in the system)
I have to run the car for a few weeks and see if this has cured the problem.
Everything is checking out o.k. now with the voltage.
If this turns out to be the problem they are going to fit a complete new wiring harness.
