Blower inoperative at all speeds

[Homie_Telefrag]

When I first bought the car, the A/C and blower system were all okay. Year after that, I only had Hi blower setting. This past month I went to turn it on and no settings whatsoever. Replaced the A/C fuse, Resistor, Relay and blower switch. If I disconnect the power wire from the blower and throw a jumper harness from the battery to the blower, it fires right up on HI. With the purple wire connected, I probed it with a test light. Nothing for power, BUT it lit up for ground. Same with the resistor wires - all ground. Anyone run into this one before? -Ben

If the Blower Motor does not operate at all, check the A/C Fuse. Here is the blower circuitry. Would also check the G130 ground connection but you already eliminated that by running your jumper. The main power has to be interrupted somewhere. I.E. fuse, corroded connection, broken wire, etc.
