1997 Cadillac Seville Blower Motor

If you have a test light, or volt meter, check across the blower connectors red and black wires for 12v, or a light, with key on. If there is no light/voltage, connect to negative terminal of battery and check red wire for volts/light. If there is none, that is powered by the inadvertent 50 amp maxi fuse in the LH maxi fuse block(under the plastic shroud, lh strut tower). If you have power, switch the meter/test light to positive, and check for battery voltage at the black wire indicating a ground(G204). If you have voltage in the first step, you either have a faulty blower, or a faulty programmer.
