This is actually driving me nuts. The blower itself works fine when hooked directly to the battery. When the blower switch is flicked on, I can hear the little passenger side relay click, and the blower relay under the hood is functional, but my blower just doesn't turn on. I also have tried resetting the circuit breaker to no avail. I do get continuity on it if that matters. I'm at a total loss. Any ideas? Could it be the resistor? Wouldn't the blower work full speed if it was?

The blower motor is wired like this....



Power (12V) is supplied to the motor from J/B4 Pin A5 and the speed of the motor
is controlled by switching to ground via a resistor block...
LO Speed - current flows thru all three VVV VVV VVV
M1 Speed - Current flows thru two VVV VVV
M2 Speed - Current flows thru one VVV
HI Speed - Current bypasses the VVV and flows directly to ground.

When the heater relay is activated by turning the switch to LO, 12V should be applied
to the motor. If there is no 12V applied, check the heater relay and its switching circuit.

The relay seems to be working ok, but I don't know if maybe a connection is bad or something. I'm not that great with electrics. I made a demonstration video.

Bumping, still can't figure it out.
