Re: blower fuse
I'd look for the short. It shouldn't be popping a 20 otherwise.

Re: blower fuse
Put a 30 amp. in it. Sometimes these old motors drag a little. If it blows that you have a short or bad motor.

Re: blower fuse
You could try diconnecting everything from the fan motor and running hot(12V) and ground directly to the motor and verify the motor works. If it does you can eliminate that as the culprit. If the fan comes on check the 12V side for a short to ground with a volt/ohm meter. I would guess if the motor is good the 12V side has a short to ground.
