Hi guys,

I have w211 - 2003 and my heated front seats doesn't work. The red indicators are not even lighting up when I press the button. I have checked the car's VIN number and indeed I have heated front seats. Also I've changed the fuses and doesn't seem to work again (I've found the fuse diagram on the internet).

What else can cause this? Or may be I have replaced a wrong fuse (#36 on the driver's side)?

Thanks!

Control unit may be faulty. DK though. DAS/Xentry is what you really need. You could always remove you lower control panel and perform a hard reset by pulling the connectors for 30 seconds or so and re-connecting.

If reset does not work, you can check fuses for precaution - interior f36 (25A) & rear SAM located behind left trunk panel f16 (20A) but as mentioned more than likely CU needs replacement definitive diagnose pull codes using MB DAS.

Thanks for the replies guys. Will STAR diagnosis show where the problem is?

Possibly in "AAC". Some actual values and guided test could very well explain your issue. That would be your next best step if all else has been performed. GL

Ok, thanks so much. I will do that in a few weeks probably and let you know.

Thanks!
