Kia Sedona HVAC issue when temperature gauge malfunctions displaying dashes instead of numbers on Kia Sedona

Some Kia Sedona owners report experiencing issues with the temperature gauge malfunctioning, displaying dashes instead of numbers, which may indicate problems with the ambient temperature sensor or the climate control electronics. This malfunction can lead to the HVAC system not producing heat or air until the gauge shows a specific reading, creating potential discomfort.
