My original post: "I bench tested the heater blower and found it blows better wired one way. Positive to brown and neg to yellow ( a 75 ) . When I reverse the polarity the air flow is weak, + to yell and - to brown. The difference is very noticeable
Then I installed the heater fan motor with the intent of getting the stronger air flow: 12v green from relay board to fan motor brown, and brown ground from relay board to fan motor yellow. Blows fuse every time Next I reversed the wires: green to yell, and brown to brown. Works, no fussiness blowing. The air flow is weak.... Is there a way to get the change the fans rotation so I get the stronger air flow like when I bench tested it ? (IMG:style_emoticons/default/sad.gif) " |
