Important Notes
Please compare your original part number and connector style before purchase. Programming may not be required for many applications, but some vehicles may require initialization or diagnosis with Mercedes-compatible scan equipment after installation.
For best results, inspect the liftgate motor, wiring, latch, hinges, and struts before replacing the module. A bad motor, weak struts, or damaged wiring can cause similar symptoms.
