Mercedes V Klasse Climate Control Problem Solved

My Mercedes V Klasse, 2010 build, gasoline engine, is having climate control issues. The panel is dead, there's a 'heating output too low' error, and the AC won't switch on. I'm thinking it's a bad cable or connector. Any ideas?

Electrical gremlins are the worst! I had similar issues with my old Volvo. The AC quit and the blower motor went crazy. Check your wiring harness and connectors, they can corrode or come loose. Do you know where to start looking?

Thanks for the reply. Could you be more specific about which wiring harness or connectors I should check first?

On the Volvo, it was a nightmare. It ended up being a connector near the blower motor resistor. Honestly, with electrical faults like this, especially if you suspect the wiring harness, you might be better off letting a shop take a look. It could save you a lot of trouble. Good luck!

I appreciate the advice. I took the car to a shop as you suggested. It was a faulty connector, and the repair was 95€. Everything is working now.
