heater fan wont work,keeps blowing fuse
can feel heat.problem is with fan
Unplug the blower motor, install a new fuse and if the new fuse now does not blow, then your cause is a bad blower motor. If the fuse still blows even with blower motor unplugged then your cause is a shorted blower motor resistor or a burned and shorted out connector or both.
