Why does my 96dodge 1500 pickup blow hot air all the time with the air conditioner on? It has a full charge of r34a in it and appears to be cycling properly.

If you are sure the compressor is kicking on and off correctly then it must have a decent charge, enough to turn the pressure switch on and cycle the compressor. So that part of it should be fine. So that would lead one to believe that you either have a lot of blocking your condenser(the other skinny radiator by the radiator) and if there is no air flow or not enough it will not get as cold as it should, cause the system works off airflow displacing heat, but if it like you said has no change at all I would definitely say you have a blend door not opening, I would check that. If not there also haha could be moisture in there too so ahh yea check that out I hope I helped at least a little
