Peugeot 407 Blower Motor Failure

I had a similar issue with my Peugeot 407. Check the cabin fan speed controller; it might be faulty. Has the electrical wiring been checked?

Where exactly is the fan speed controller located? And what kind of error were you getting?

It's usually near the blower motor, under the dash. My 407 had airflow problems, and error memory pointed to the blower motor in the end. I'd suggest going to a workshop.

Thanks for the help. It was indeed the blower motor; it cost me 365€ to get it fixed.
