Trajet AC Failure Temperature Sensor
Summary of the thread
The 2002 Hyundai Trajet is experiencing an issue where the air conditioning (A/C) won't turn on, and an error message related to the temperature sensor in the heat exchanger is displayed on the speedometer. This problem could be due to a defective temperature sensor, which might affect the A/C system's functionality. The suggested solution was to take the vehicle to a workshop for a proper diagnosis. The workshop confirmed that the air conditioning control unit was defective and needed replacement.

Thanks. You mentioned the temperature gauge potentially 'acting up'. What specific malfunctions or irregularities should I be looking for?

Okay, so by 'acting up,' I mean is it reading way too high, way too low, or just plain erratic? If it's off, the whole system might think the engine's hotter (or colder) than it is, which can mess with the A/C and other stuff. Honestly, it sounds like it's time to get it to a workshop. It's probably an air conditioning control unit defective, which could be expensive.

I appreciate the insight. I took the vehicle to a workshop as suggested. The diagnostic confirmed the air conditioning control unit was defective, necessitating replacement. The repair cost amounted to 980€.

Whoa, that sounds rough! A/C not working is a nightmare, especially if the temp gauge is acting up too. Is the engine overheating at all? Maybe check for a coolant leak? A bad sensor can throw everything off, but it could be something else entirely. I'm no expert, but I'd start with the basics.
