Re: heat/ac fuse keeps blowing
The only thing that blows fuses are a shorts down the line. What I would do is to start at the end of the circuit and work my way back to the fuse as follows:
Disconnect the blower's motor, install a new fuse, and turn power ON. If the fuse blows, then you have to consider the switch itself, the resistor block, and any of the power leads all the way to the motor. If the fuse does no blow, then the motor is bad. |

Re: heat/ac fuse keeps blowing
Opps! forgot the AC circuit. But for now try the heating circuit and see what happens.
