Blower Motor Resistor, 2002 Infiniti QX$
When my daughter informed me that her blower motor would only work on high speed, I went directly to 1A Auto on line and ordered the resistor/amplifier.
The new resistor was around 1/4th the price of an OE part and it arrived in two days.
The install went smoothly and the blower motor speeds have been fully restored!
I would recommend this part to a friend.
