Long-time lurker, first-time poster. Have a 2000 UJZ100 that I’ve owned for 18 years.
I’m having a weird problem with my climate controls. All the buttons work (... I'm lucky with this known issue), but all three knobs suddenly stopped working. The climate control seems to be set (stuck?) on “Auto” and at a reasonable temperature. So now in the the heat of the summer, it blows cold. In the winter, it blew warm. The system auto-regulates to the set temperature — so the fan’s speed adjusts, for example.
But the knobs don't work. One day they did, and the next day they didn't.
The AC on/off button works, so when the system is cooling, I can select “off” and air does get warmer so I suppose the compressor does shut off. The fan motor continues to blow. There are no noises when adjusting the knobs (no clicking of baffles or anything).
I’d like to recover the functionality of the three knobs (temperature, directions, fan speed).
What do you think the problem is? How do I diagnosis it?
