Thanks scott. On the blower motor there is a orange and black wire. And the other two wires attached and grounded to the car is black and black-white but one wire is relatively thicker that the other. That goes to the orange right?
I have a 99 Toyota Corolla and the blower was very loud and shaking so I decided to go to O'Reilly's and get a new blower and fan but when I replaced it I had to splice the wires. The old blower has a sensor plug but the new blower had an orange and black wire fixed to it. I spliced and cremped...
