S40 fresh air blower issue

Hi, I'm having a problem with the fresh air blower on my 2003 Volvo S40 diesel. The blower motor isn't working, and I'm seeing an error stored in memory. I suspect the blower motor is defective, but has anyone else run into this before I start replacing parts? Has anyone experienced something similar with their S40's air conditioning or heater fan?

I had a similar issue with my S40 a while back. No air flow at all, regardless of the climate control settings. Did you check the fan speed controller?

Thanks for the quick reply. I haven't checked the fan speed controller yet. Where is it located, and is there a simple way to test it before replacing the blower motor itself? I'm trying to avoid unnecessary costs.

Honestly, I didn't test anything myself. When mine went out, I just took it to a workshop. They confirmed it was the blower motor and replaced it. Probably the best course of action if you're not comfortable with electrical testing.

Appreciate the input. I took your advice and had a workshop look at it. They confirmed the blower motor was defective. Got it replaced, and now the air conditioning is working perfectly again. Total cost was 365€.
