Mine too. 1996 Chevy K1500. I found the heater speed resistor on top of the heater box behind the dash and it had a open thermal fuse inside it. I got access by removing the glove box door but found it a little difficult to remove. I just soldered a wire around the fuse as I have always done for this problem in many domestic vehicles.

My 2004 Jeep Grand Cherokee AC only works on high does anybody know why the AC won't work on low or medium?
