Even with the A/C on, hot air continues to come out of the vents as if the temp guage was turn up as hot as it will get. Couldn't find any blown fuses. Is there a separate thermostat, other than the engine? Could the knob be stuck?
I would look at the air blend doors first, it sound like they are not working or your control in the dash is not working send a signal to them. they work by changing the air from hot to cold or in between.
