2006 Hummer H3 with wiring problems! No blower motor speeds!

Todays video is a 2006 Hummer H3 that came in for an inoperative blower motor. This proves why you should always test the circuits prior to throwing new parts at it. 9 times out of 10 its either a resistor or the blower motor but that 1 time can cost ya!

I had this exact problem. I fixed it and a few days later the blower motor went out again, no blown fuses, relays or diodes, I replaced the resistor and still nothing.
