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.
These can often be difficult to bolts to remove. You may need to use a ratchet with a long extension to provide the necessary angle to access and turn the bolts. Pull the motor and harness out as one assembly. Once you have the assembly removed, you can separate the two pieces and replace the one that is malfunctioning. Re-install the motorregulator assembly. Once you have replaced the malfunctioning part, whether it was the motor or the regulator, it is time to slide the assembly back into the door's interior and bolt it back into it's original position.
