A very common part that often causes this situation is a failing blower motor resistor. Sometimes as they start to fail they drop the low speeds one at a time and eventually leave only the high speed. Other times they drop all lower speeds at once. It's one place I would start with. Maybe less than $30 to buy, but may not always be easy to get at in some GM products. Not sure about your truck but I think that some of their cars have them buried behind the glove box.
