My ventilation motor only works on the highest speed and the Air conditioning is not activated on this setting.
The a/c is turned on and it seems to work on the lower speeds, but the blower engine doesn´t work on this setting.
A bit confusing, but it´s th best I could explain.
I think the resistor or transistor ou eletronic comand module (diferent names for the same part I guess) needs to be replaced.
I´ve been told to look for the part 644178, but it brings to parts that fit to diferent car models.
What reference should I be looking for?
I was trying to find a match for this part number without having it dismounted - of course the reason for this is not having the blower out of order while I wait for the shipping of the part and havind double the trouble on the removing process...by the way...is it to difficult to remove or it´s made to be easy as changing the ventilation motor? I already burned 1 motor vent...and now this resistor... in 6 years?? don´t understand what am i doing wrong. Might it be because i use the blower to much? To hot? Car enigmas
