I have an 05 S40 and for the past few months my heater has been staying on constantly for a few days, then back to normal. I have to close all the vents because it is always blowing hot air. When I turn the temperature knob, it shows the little heater icon. Even changing it to AC, the heater icon still shows and it still blows hot air. Before it lasted a few days then went away, now it's been over a week and it's still on. Any ideas??? Summer here is brutal, and I NEED my AC

I have two little kids and need to get it fixed ASAP. Hoping to avoid the dealership. Thanks!
