Skoda Rapid Climate Control Problem

Sounds familiar! I had similar climate issues with my Opel a while back. The air conditioning wouldn't kick in and the temperature control was all over the place. An error code was also stored. Have you checked the wiring and plug connection to the sensor itself? That was the culprit in my case. A loose or corroded connection can cause the sensor to send incorrect readings, which will affect climate regulation. Worth a look before you go deeper.

Interesting. When you say wiring and plug connection, are you referring to the connector at the sensor itself, or further along the harness? Is there a specific area I should be inspecting for corrosion, or any specific trick for testing the connection?

Yes, I was referring to the connector directly at the sensor. Usually, that's the weakest point. Look closely for any signs of green corrosion on the pins or within the connector body itself. Sometimes, a pin can be slightly bent or pushed back, preventing good contact. Gentle wiggling of the connector, while the car is running (be careful!), might give you a clue, if the climate control starts working intermittently. However, given your symptoms, and to prevent further climate issues, it might be best to have a workshop perform thorough sensor diagnostics

Just to let you know, the diagnostic pointed to the internal temperature sensor. As suspected, it was a faulty connection. The repair, including sensor diagnostics, came to 95€. Climate control is now working flawlessly again. Thanks for the advice!
