I have been troubleshooting my AC/Heater which has no fan speeds. I can disconnect the hot wire to the blower motor and have 12v at all connections including the hot wire to the blower but when I connect the blower the voltage reads 0 at those same connections. I repaaced the blower switch, resistor (used from e-bay) and the mode switch which I had a apare........still won't run. I ran the blower motor from the battery to the dark Green wire at the switch and it runs. In checking the resistor I did a continuity check and it's fine......took my ohm meter and check resistance and get between .5 & 1.5 ohms resistance......what should the resistance be,,,,can't find a NEW resistor anywhere if it is bad.....help! (not sure if this is the proper posting site)
