Fan blows fuses
The heater fan on my dad's 1990 keeps blowing fuses. It does ok on low but blows fuses on high.
Is the motor going bad? I figured the bearings is dry. What do you guys think?

Motor sounds like it is going out and pulling too many amps. There is a resistor that lowers the voltage to the motor during the lower speed settings. If that goes bad it won't work on the lower settings. Since your blows fuses on the high setting it should be the motor.
16 years of blowing is a long time for a 12V motor.
