09 Yaris Heater blower problem - Toyota Yaris Forums

motoxxx3 · 09-16-2010, 06:50 AM

I have had another look, and the only other thing I can see is a black module with 'fins' on it. It is in bolted to the firewall in the centre of the car - directly in front of the silver SRS ecu behind the centre console.. difficult to see colour of the connectors/wires though. There does not seem to be any module mounted on the firewall in the drivers or passenger side footwells.
I just discovered last night & this morning that it seems like if Iam driving with the car's lights on the heater blower runs at it's correct speed all the time and does not fluctuate with accelerator position. If I turn the lights off it starts to fluctuate again.
Iam going to try this again over a longer period just to be sure.
