CHEVY BLOWER FAN ONLY RUNS ON HIGH AND WON'T

2002 Chevrolet Silverado

Heater problem
2002 Chevy Silverado 6 cyl Two Wheel Drive Manual 230000 miles

My heater only runs on high even when I have it shut off. It also continues to run after turning off the ignition and the battery must be dissconnected to turn it off. What could this be?
