A symptom list would be ideal.

If your blower doesn't work on one or more speeds probably your resistor.


If it doesnt work at all could be your igniton switch you'll need a multi meter to test the voltage at the switch. It involves removing the knee panel.

Rarely do I see BCMs go bad in the pre 03 grand prixs. That would be the very last thing I'd replace..
