Jerry,
Since you lost the passenger's side control light as well as the driver's side blower motor, the first thing that I would check is the A/C control panel. The only way to diagnose an electrical problem like this, is to take a good voltmeter and find out were the power stops.
If there is power in and out of the control panel to the blower motor, go to the driver's blower motor, and if there is power to it you have a bad motor. If not, trace the circuit back until you locate the open in the circuit.
