Hey guys. My blower motor wouldn't turn on one day, so I figured I'd replace it... Well, six months later, when winter hits and I finally give in to the cold, I did replace it. Problem is, the blower motor still doesn't turn on. I'm not sure what it is at this point, but here's what I've got so far:
1. The heater fuse has power.
2. The wire that goes into the blower motor has power.
3. The wires that control fan speed have power in only the high position when it's unplugged from the side nearest the blower motor, and when plugged in, have power in all wires regardless of fan switch position.
At this point, i'm guessing that it's the climate controls themself, but the buttons do make the air switch from recycle to vent, and changes position of the vents from upper vents to lower vents to windshield defogger, so those buttons do work. Could it be the fan speed switch itself inside the climate control housing? Or could it be that thing that the wire harness that comes from the fan speed switch is plugged into? I don't exactly know what it's called, but it looks like a black sort of "switch" with a spring "sensor" inside the blower motor housing and is labeled lo, m1, m2, hi. I'm assuming it's a resistor. Could that be the culprit? Anyone please help, I'm freezing my ass off here with no heat. Thanks again.
