Hi Tysamigo,

What problem were you having with the blower before? Did the motor not work at certain speed settings, if so, which ones? Or did it not work at all. If you follow the wiring diagram in the original post, it should help you to troubleshoot.

With a test light, check for power at each point along that circuit.

As you have the blower resistor out, make sure it is disconnected from the battery, then use an ohmmeter with one lead on the terminal that had the Blue/Black wire attached, then touch the other lead to each of the other terminals. If the resistors are OK, you will have a reading at each terminal with a different resistance at each one.

Hope this helps.
