Movano Blower Motor Fault

Afternoon. My 2004 Renault Movano diesel, 153760 km, has developed a strange fault. The blower motor refuses to operate. Diagnostics point to an AUC sensor fault. I've checked the sensor itself; seems fine. Suspect cable or plug connection. Anyone seen this before?

Summary of the thread

A 2004 Renault Movano diesel experienced a blower motor fault, with diagnostics indicating an AUC sensor issue. The sensor itself appeared fine, leading to suspicions about the cable or plug connection. It was suggested that the auto recirculation feature might be linked to the blower motor issue. The problem was resolved by fixing the cable connection to the AUC sensor, restoring the blower's functionality.

I had similar issues with my Movano, though I didn't check the diagnostics. Does your climate control have auto recirculation?

Indeed it does. Is the auto recirculation linked to the blower motor?

I believe so. If the AUC sensor is faulty, it might be telling the system not to allow outside air, which affects the blower. I'd suggest taking it to a workshop; they'll diagnose it properly.

Thanks for the suggestion. It was indeed the cable connection to the AUC sensor. 95€ later and the blower is working perfectly.
