Truck is a 2001 360 V8.

I haven't been using my AC or heat (summer in south Ga, too damn hot already) lately, about a week or so without it, by choice. About two days ago I noticed that with ALL the heat/ac controls OFF that a steady flow of heat (very warm too, almost hot) comes out of the dash vents.

Today when it was doing that I turned on the AC to Max and it continues to blow hot air.

I'm completely lost as to why it just "magically" started blowing heat all the time.

Advice please.

Thanks.

 

A 2001 has a small electric motor that operates the blend door. The motor may be bad or the plastic lever might have broke. Pretty common issue. Here is the fix for the lever.
