Heat system makes heat, blower motor appears to be brand new. However, blower fan will not do anything, no matter what I set it to. Wasn't sure which part to replace to fix this problem. Took out blower motor resistor thinking it was that, but it appears to be just fine. Someone had previously installed an amp in it and did a poor wiring job, old amp wires and plugs still inside dash cavity. Some wires coming from heater selector board are testing as "dead" (purple and black on left side, and a blue and black near the middle) but the other wires in each cluster are testing good. Please help...
