Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Expert:  rpmdiag replied 10 months ago.

The most common problem would be the motor itself, but you can confirm this with a bidirectional test with a scan tool, it will confirm whether it's the module or the motor.

Thanks, Ron
