I've got a 96 Isuzu rodeo that seems to have electrical problems. First it was the heater, which blew a 20A fuse every time it got really cold overnight. Replacing the fuse worked but now the heater/AC only blows at full blast, not any of the lower levels. Is the heater motor going? Is it the heater itself?
Now the front windshield wipers are not turning on. I can't find a fuse for the wipers so I don't know if it blew too, but I'm worried that this new problem is related to the heating problem. If fuses keep burning out, what should I do to fix it? Is it the motors on the individual parts or the battery or what?

The heater motor is fine. There's a resistor that controls the motor at lower speeds. It's bypassed when the motor is on high, so when it goes bad, that's the only speed the motor works at. It could be causing the blown fuses too. The wipers are another story. Only some troubleshooting with a voltmeter will decide if it's the switch, wiring or motor.
