Re: wrangler blower motor problem
They're customarily mounted inside the heater box. They generate a significant amount of heat, and being in the airflow keeps them from overheating. Look around for a three or four wire plug. On CJs it's forward of the bottom edge of the glove box.
They don't often burn out. It's probably a loose connection, or it could be that the plug is off completely, since the resistors aren't in the high-speed circuit.
