Peugeot Expert air conditioning issue

I had a similar problem with my Expert. Same symptoms. Check the cooling system; might be a coolant leak impacting the sensor.

Thanks for the reply! Could you elaborate on checking the cooling system? What exactly should I be looking for?

Just look for any signs of coolant leaks around the heat exchanger and sensor. If you see any, that's likely the issue. But honestly, these things can be tricky. Best to get it checked at a workshop.

Thanks! I appreciate the info. I took it back to the shop, and they confirmed the heat exchanger temp sensor was the culprit, just like you suspected. Getting it fixed. Cheers!
