Ac fuse blows when ac/heat turned on. Manual control. Blower has a separate control than on/off control. I've checked the wiring and can't find any obvious breaks or pinched wires. I've got a good ground to the blower motor. I've replaced the blower motor, blower motor resistor, blower motor relay, control panel. Checked for power at the resistor and I only have power on the high setting. Blower motor doesn't operate at all (but fuse blows instantly when heat/ac is turned on). I don't know what to to try next.
have the same problem?
