Now that you have access to the motor, unplug the harness and verify the motor windings again while directly in front of the motor, not from the CCU harness. See if it still shows the same readings as before.

OK, but how exactly do I verify the motor windings?

Page 10 of the tech sheet I gave you.

Missed the link before, thanks.

Isn't that the same sheet that was tucked into the plastic the bottom front panel?

Look familiar does it? :)

It's the bible as far as a technician is concerned....

OK, I measured the resistance per the pin matrix and got 5.8 to 5.9 ohms for each reading, which is pretty close the the 6 ohms they are supposed to be.

What should I do next?

Don't know about you, but I'd be on my way out to my truck to fetch a new MCU. The motor is OK, just be sure the tiny wires on the connections to it are ok.

OK, except my truck doesn't have a MCU in it.  In fact, I don't even have a truck...

Anyone got any leads on where I can get my hands on a MCU?  I am in Hawaii, so it will have to be a place that ships...

Thank you

The last time I checked, Hawaii is still America, so shipping is a moot issue :)

Follow this link to order the motor control, part # W10163007

Last thing - does the testing imply that that is what my problem is?  I'm trying to avoid paying $150 plus shipping to learn that that does not solve my problem (if that is possible...)

Free help does not come with guarantees.  You can probably return the part if it does not help.
