When you say it won't start, are you referring to the grand am won't turn over as in it's dead or are you asking what's wrong when it does turn over but won't start?
I have a 1978 coupdiville cadillac my blower quit working and there is a relay above your fuse box and if it goes bad your heater wont turn on. I had to replace it with a after market heavy duty relay away from where it is originally plugged in. Also my ground wire connection was dirty and wouldn't turn on until I cleaned the connection so try that and see if it works or you might need to replace the motor.
