Have you seen this yet?With it getting chilly down here in the south I've been wanting to use my heater in my 07 4WD X, but when I go to use it on level 1,2,3 they dont blow. But on level 4 it works. Anyone know how to fix this??
Loosing some of the fan speeds is definitely the resistor card failing (which controls the fan).
My 08 X - replaced the factory resistor card ~2012/2013. Replaced resistor card again 2015. Read here on the forums about folks regularly replacing the resistor cards every year or 2. The 3rd card crapped in 2017. Replaced the card plus the blower motor as the forums suggested the blower motor was degrading and drawing more power thru the resistor card burning out the card. Now 2021 and still on the 2017 resistor card.
