I have a 2002 chevy express 1500, i just noticed today that i got the same problem: the fan blower turns on when the car was off and without the key on the ignition, so if you find a good response, please let me know at erasbar@hotmail.com thanks!
check the blower Motor Resistor thats what was wrong with mine and what i was told by the dealer ship and it is $110+ part
