Peugeot 107 air conditioning failure

Sounds familiar! I've got a 107 too. Had similar HVAC problems last year. Error codes and the AC blowing warm. Have you checked the wiring and connectors to the rear vent flap motor? That was my first suspect.

Cheers for the reply! You reckon it's just a loose connection? Where exactly is that vent flap motor located? I'm not the most mechanically minded, to be honest. Is it easy to get to?

Yeah, worth a look. On mine, it was a dodgy plug. But honestly, fiddling with car HVAC stuff can be a pain. If you're not confident, I'd advise a workshop. They can diagnose it properly and avoid you messing something else up.

Thanks, appreciate the advice. Took it to a local garage, and you were spot on – faulty connection! New plug and wiring repair cost 95€. Aircon's freezing again!
