Q: What is the average service life of a qualified lifter motor for Mercedes trucks?

How To Identify A Faulty WINDOW LIFTER MOTOR FOR MERCEDES TRUCK

Early identification of faulty window lifter motors can avoid sudden system stuck that traps the window half open during rainstorms or long-distance driving. From actual test cases, technicians can finish full diagnosis within 10 minutes without disassembling the door panel.

1. Turn on the truck ignition and press the window lift switch for 3 seconds, listen for faint buzzing noise inside the door panel: if you hear continuous noise, the motor is stuck and needs replacement
2. Swap the switch connector with the other side functional window, if the non-responsive window still does not work, the motor is the faulty part
3. Use a multimeter to test the motor power input terminal: if it gets 12V current while the motor does not run, the internal coil of the motor is burnt out
4. Check the gear of the motor: if you find broken plastic fragments when you take out the old motor, the wearing gear is the direct cause
