The problem you have is likely not going to be solved this way. First you don't give us enough info on what type of system u have and second without a wiring schematic it is nearly impossible to fix without being there. Even being there it would take some time to figure out where the wiring is wrong. A more detailed description may help.

SOURCE: Heater blowing out cold air

Yes you could have a bad overload on the heater element which is fairly simple to fix. To test for this pull the heater out and get an ohmeter set it to continuity and check the continuity first through the entire heater element then if there is none pin point the overloads and check to see which one has no continuity.

SOURCE: 20 year old central a/c heater not working

Check your thermostat and mode selector setting, thermostat setting should be set at warmer and mode selector setting should be at low heat or hight this is applicable for manual unit.
If it is a remote control just set the remote to heat mode.

SOURCE: Problem with GE Zoneline 5200 model

Heat pumps have saftey circuits that prevent liquid flooding of the compressor. Inadequate airflow across the evaporator in cooling can trip this circuit. Have your package unit serviced with particular attention to cleaning the evaporator coil and be sure your filters are clean and changed frequently in the summer months. Hope this helps GL!

Why would my heater blow out cool air when sitting still and then hot air when going down the road and then it's not all that hot


Try flushing or blowing high pressure air through the heater core lines. its sludge build up and need to be flushed through heater core only. check antifreeze fluid level. only put in straight antifreeze, do not mix. most people do not know what mixture should be, so be safe and add straight, it will not hurt it, i run 100% straight antifreeze and never had a problem or worry about it ever freezing and cracking my block, heads or radiator cracking.

My 04 dodge stratus heater/defrost doesn't work very good. You can take the dash control unit out and mess with the wires on the back of it and it will blow hot air for a little while. I use to do this...


Sounds like the control unit or wiring (since you could mess with the wiring to get it working). The controls aren't controlling the dampers in the ductwork to control hot/cold, etc.
