Hello all, I purchaced a 1992 RR County Classic last year and am getting it back into shape. I just got it to the point were I can drive it but found that I have not heat. I have already replaced the thermostat and water pump. The lines to the heater core are both hot, so the heater core is circulating. Yet all of this working well it still blows cold air Any kind of help or advise on things to check would be much appreciated.

 

Did you bleed the cooling system? You may have an air bubble in the system.

 

It would also be overheating if that were the case.

My boss has a 94 with a similar problem. He has traced it down to a cable that has snapped inside the dash. The cable opens and shuts little doors to let in either cold or hot air. Although the cold side works for him, the hot side does not. He has not repaired the cable yet, so I cannot give you any detailed instructions.
