Blower not working for heat but works for a/c

This is a 1976 pontiac wagon. The blower motor is good & the heater relay was replaced. Still only comes on in the a/c position. Any suggestions?

    Are you sure the blower is not running? Or is it just not blowing out the correct vents?

Well if the ac blower works and the relay has been replaced then it is either a short in the wires or it is a bad switch. I recomend the switch from a junk yard. then if is it then you can buy a new one if they are reasonable.

1997 pontiac grand prix gt,the heat and defrost will not work. have replaced the blower,5 prong fan relay,and the fan control switch.do not know what else to do. i have checked all fuses,and all are fine


I had the same issue, however my blower motor did not work at all, heat or AC, it just did not work. It was the blower motor resistor. When I took mine out, it was brown and melted. Got a new at the junkyard for a few bucks. Works great now.

No heat


are you getting any air into cabin?? cause if you ar getting air but its not coming out hot then it may be a bad heater control valve. If you are not getting any air period then its a bad blower motor or blower motor relay.

This sound like the blower motor relay(lo relay) is wired in to the head light switch voltage.You need to follow the wire from the blower relay (there should be 4 wires) thats hot when the ignition is on and make sure it goes to the blower motor.It sounds like a couple wires got switched.
