Re: no heat in my 83
Do you have air coming out of the ducts but just not warm air? Or is it warm air, just not a lot of force to the air blowing out? Lots of air with no heat - I suspect you need a new heater core, assuming the thermostat is the right temp and working. Hot air but no force - I suspect weak blower motor or relay.
Does the A/C work properly? Also, as mentioned, the cable going the the door in the heater box may not be working properly or disconnected - you should be able to feel/hear the door open when you move the control lever to the heat marking - there is a bit of resistance in the cable/lever assembly. |

Re: no heat in my 83
I was thinking blower motor as well. is it blowing but just isn't very hot or are you getting barely any push?

Re: no heat in my 83
i would definitely check your blend door. Take the glove box out and feel for it to be all the way to the left in its movement.
