R Klasse Fresh Air Blower Failure

I had a similar problem with my R Klasse climate control. The air flow was practically non existent. Did you check the fuse for the blower motor? It's worth a look before diving into more complex diagnostics.

Thanks for the tip. I did check the fuses, all seem to be fine. I also ran a diagnostic and got an error code related to the blower motor itself. Did your issue also throw an error code?

Yes, it did show an error code. Given that you've checked the fuses and are still getting an error, it does sound like the blower motor is the culprit. I ended up taking mine to a workshop. Saved myself a lot of hassle.

Appreciate the confirmation. I suspected as much. Got a quote for 365€ including parts and labor. Seems reasonable enough. Will get it sorted at the workshop.
