my heater blows no air at all majority of the time. occasionally works for about 15 minutes or so. also the buttons to change where air blows from don't work. i bought a chilton manuel but it doesnt have any info except how to change blower motor. can anyone tell me if its the motor or if i just need to replace the piece with the heater controls?
