In case you don't know who take your car to for auto electrical repairs, you can ask for references from fellow motorists; ideally friends and relatives who are unlikely to mislead you in this (potentially sensitive) matter. As long as they have faced such situations before, they are likely to guide you on which service providers to visit; or at least which service providers to avoid.
Use a multi-meter to make sure that the motor is getting the correct voltage. Attach the probes of your multi-meter to the motor’s plug and toggle the switch up and down. Make note of the voltage in both directions. Your owner’s manual should list the specific voltage required. Ensure that the window moves freely during this test. There should be no slow spots or blockages. Unplug the motor. If you the motor is getting the proper voltage but not functioning properly, you likely need to replace it. Start by unplugging the wiring connectors from the motor.
