cab heater blower dead on all speeds, ????
high speed never uses a resistor block,
high is full 12vdc to the blower (fast max)
fuse 37 and fuse2 not blow or wrong size or blower is dead.
the blower is 2 pin 1DC motor, and can be hot wire tested easy in place to see if it is bad. fails this simple test, the controller is not bad.
BINGO this car.
most modern cars have no such resistor block at all
the BCM and CCM climate control module modulates the fan
ending blown up resistors forever , (glory on high)
did you check fuse first and scan the PCM next/ oops?
your car came new with
2 HVAC types
full
auto and manual controls, so I will now answer for both.
Neither has a resistor block, it has blower motor control processor 6 wires. (end block hunts)
I will read your SM manaul to you now
ok both work the same for blower,
now where is it.
B for blower, 1 for here it is, the controller processor
the manual tells all steps to reach here. RTM"?
