Blower Fan Diagnostics
My blower fan for my climate control stopped working and I tried the following.
First off I test voltage at the harness and still got 9.5 volts on high speed, then I applied direct 12v from the battery and the fan started right up. All fuses and relays related to the blower check through fine. So what can it be? Blower module doing wacky things or what?

So between the harness and the fan, power was lost. Did you check ALL the wiring? Make sure the fan'* end of the wire in the harness made contact with the lead from the other end of the harness.

K, I think I got you now. Tomarrow I'll pick at the prongs inside the harness connector and pull them "out" a little to make sure the blower leads make a good connection. Otherwise what other connectors to check? The back of the ECC (electronic climate control) itself?

This one is a stumper because there is voltage at the fan harness and the fan runs when voltage is applied to it. Therefore it has to be a bad connection at the fan, doesn't it?
I might be tempted to remove the pins from the harnesses and touch them together to test/ensure a proper connection.
