Mercedes B Klasse Air Conditioning Problem
Summary of the thread
A 2012 Mercedes B Klasse diesel is experiencing an air conditioning issue, with an error related to the rear ventilation flap and a lack of cooling. The problem could be due to a faulty cable or plug connection. It was suggested to check the air distribution and circulation settings, but ultimately, the issue was resolved by fixing a faulty connector on the flap motor at a local garage for 90€, restoring the air conditioning functionality.

Air distribution Air circulation Can you explain what you mean Where exactly should I be looking to check these things I'm not exactly a mechanic

The air distribution setting controls where the air comes out – face feet windscreen Air circulation is whether it's pulling air from outside or recirculating inside air If either is stuck it can affect the whole climate control system But if it's showing an error and the AC isn't cooling it's likely the flap motor or wiring like you suspect Probably best to get it checked at a workshop

Right I get it now Thanks for the clarification I took it to a local garage and you were spot on Turns out it was a faulty connector on the flap motor They sorted it for 90€ Air conditioning is working perfectly again
