it is not as simple as that. the fact that it is not 0 ohms or infinity makes it ok as you are measuring the resistence of the windings in the motor. it is the controls that need checking from the ecm. you need a scan tool to manipulate the motor to work from full open to full closed.

as i said, it is not that simple and requires a scan tool for further checks.
