    How do I troubleshoot my heater?

    My 1998 Explorer Heater fan works intermittently. When it works it works on all speeds as normal, but then next time NOTHING! Not a whimper out of it. How do I troubleshoot this? Where do I start? Should I suspect a switch? Or a relay? Or a resistor? Or all three?
