I have a 2004 Mitsubishi Lancer ES (110,000 miles) that is working perfectly with just minor, small hiccups. A few months ago I took the temperature control console off (the giant plastic piece on the dashboard that has the ac/heater controls and knobs) to replace the wires because the fan level knob was stuck. That was successful.
However, a few weeks later the AC button is stuck on (green light on). The AC light will not turn off no matter what. I’ve tried to take the plastic piece apart and even unplugged the console to take a look at the actual button itself and it all seemed to be alright (im no mechanic). I’ve tried pushing it a hundred times, in different sequences, anything you can imagine - will not turn off. As a result, we have no heat.
Was it my fault? Did I do something? I don’t know. What do you gentlemen think? I’ve been told that the blend door is stuck but this is a Mitsubishi and every part of it screams “Don’t touch me!” so I’m slightly scared of going too far into the dashboard. Please help, winter is coming and my wife will need that heat. Thank you much!
