If the failure is that the blower motor doesn't run at all, they are
probably failing open. *If the failure is either that the blower motor
runs at maximum speed, or a fuse blows, then they are probably failing
shorted.


i guess they call replacing a simple resistor with a bunch of
transistors.... "progress"

i'd replace the module with a bunch of power resistors and maybe a PTC
(self resetting) fuse
