Peugeot 208 Defrost Air Distribution Fault

Sounds familiar! I had a similar issue with my 208. Check the blower motor; the temperature regulation can go haywire. Has the air circulation been affected too?

Interesting! Where exactly is that located, and what should I be looking for specifically?

It's buried deep in the HVAC unit, a real pain to get to. Honestly, I'd bite the bullet and take it to a workshop. Probably just a loose connection, but you could end up making things worse.

Thanks! Took your advice and went to a shop. Turned out to be a corroded connector, just like you suspected. 95€ later, all sorted! Cheers!
