2008 Pontiac G5 Question: what would be the problem if the heater worked and then went out.

poss bad blower motor or resister - globalhelper
sounds like a bad blower motor. when you hit the blower motor it will knock the armature loose and it may work for some time but you will need to replace the blower motor to correct the problem for good. - superiorauto95
