air blower starts at ACC - wastes batteries - Toyota Yaris Forums

D-Flo · 04-18-2017, 06:00 PM

When I turn the ignition to ACC in my Yaris SE 2012, the cabin air system blower fan starts up for some odd reason, even when I have the fan control knob turned to off.

Any way to stop that from happening? I like to sit in my car sometimes for 30+min to power up and use my smartphone. But the batteries drain faster with the blower motor spinning. Any way to turn off the blower motor completely?

Thanks.

did you find a fix for this? my 14 yaris is starting to do the same thing.

Sorry iam_elmanny,
No easy solution yet. I was able to find out where the power dongle attaches to the blower fan, and conceivably I could disconnect it, but that would mean the cabin air blower would simply not work any more (no A/C, no blowing of air on hot days, no front window defrost, no nothing)
