Mercedes GLC Hybrid Power Window Failure

It's not unusual for window regulators to fail early, even on newer cars. The error code suggests that. Have you checked the power window switch itself A bad switch can look like a bad window regulator. Do you hear any noise when you try to use the power windows, or is it silent

Good idea about the switch I didn't think of that How do I test the power window switch If it's not the switch, can I replace the window regulator myself, or should I get a professional

Testing the switch means checking for continuity with a multimeter. If you're not comfortable with electrical testing, a workshop might be better. You can replace the window regulator yourself if you're skilled, but it can be tricky. You'll need to remove the door panel and maybe deal with the window track. A professional might be safer, considering the risk of damage.

Thanks for the advice I went to a local mechanic. It was the switch. A new switch cost 200€ and it's fixed. Thanks for the help
