Question about 2004 Pontiac Grand Prix
Look for overheating wires melting their insulation just under the glove compartment in the passenger seat. This is the blower for the heater and for the air conditioning

i have an Idea. first of all make sure that all of your vents are not plugged up. next check your heating coils to find out if only one side is hot or the other is only cold. i need more info

Most often on those the motors are shot. as soon as they are activated they overheat and slow down or stop. Only way I know of to repair is to replace them. You will need a manual to do this or do them one at a time so you can check how it goes back together by looking at other one. Motors are riveted in and need to be drilled to remove...use small bolts to re-attach.
I've seen motors online for about $30-40 each.

Two things can be the problem,first,try adding ,a little freon,if it is low,it will only cool one side,then if this does not help,there is a door actuator motor that controls this,it could be not working,the dash has to come out to replace this actuator motor,if this was at all helpful,please rate,thank you.
