The saga with the blower motor goes on...

Doggonit I wish I was an electrical wizard.

I had a bad blower motor and replaced it. The new motor didn't work. I posted a thread and many helpful responses flowed in. Much thanks. I changed the climate control unit and blower regulator with salvaged ones. Eventually, I got the blower motor to consistently run. However, the motor runs continuously. The fan speed is medium speed only. The fan speed buttons do not regulate fan speed. The fan off button does not stop the fan. Any thoughts folks? I tried each climate control unit in hopes of isolating the problem, but each work identical here. So in short, the blower motor runs continuously on medium speed and does not shut off.

Also, prior to the blower motor going kaput, I replaced the monovalve because regardless of where the temp wheel was set, only super hot air was blowing out the vents. The new monovalve has not fixed that problem.

Sage advice is requested...
