1991 subaru loyale ac fan does not work fuse is ok

Is the blower motor not blowing or the fan on the radiator not working? didn't say exactly which it was. If it's the blower motor and the fuse is good, it could be one of 4 things. Broken wire, bad fan speed switch, bad resistor switch (controls fan speed) or bad blower motor. Check for power to the fan speed switch, if it's good move to the resistor switch( this switch is normally located near the blower motor and is bolted to the air box to keep it cool) Pull it out and check it. It could be burnt up. If so, replace it but before doing so check to see if your blower motor works by hooking it straight up to a power source. Most of the time on older vehicles the resistor goes out due to excessive dust build-up and finally burns the coils out or it just dies of old age.
