1. Check engine light keeps coming on. Determined that O2 sensor is failing.

3. The air conditioner is failing. Even when temp (all) are set to 60 degrees Fahrenheit the car is 100 degrees hot. The ambient temp is about 14 degrees Fahrenheit. Now, i turn the AC button off, the cabin cools down. It sounds like the compressor isn't working after the air is reheated.
Anyway, can anyone with a 7 or a 5 living in a climate zone that is cold tell me if the AC/MAX button gets disabled? When I press the AC/Max button, nothing happens and the light above the button won't turn green. Could this be disabled due to cold ambient?

I am sorry to hear that.
Before we go any further Did you make sure that the dials beside the vents are dialed to cold and not hot[red vs blue].I think if the dials are turned to red they will blow hot air regardless of the temp set at the control panel[atleast that was what I was told].I just tested the AC function in my car.In my car the AC max button doesn't light up when I press it.The ambient temp today is appr 10 degree F.I doubt there is a light above the AC max button as its on the Black panel[cant see it,The other buttons beside the ACmax button have an orange light above them on the black panel]. The green light above the AC button does light up when pressed though.
Mine is a 2014 750lix.Regarding the ACmax button either mine is not functioning or it doesn't turn on because of the ambient temp.
