Heater question

So, i thought my heater core was the issue, but now i dont know. for the longest time on any a/c setting my heat would only pump out luke warm air. I flushed/refilled the radiator, flushed the heater core, burped her, and today i noticed that the heat only gets hot when im in any setting without the a/c snowflake. (is this normal with TJs???) strange
Only additional info is that when i get going 65mph+ my air just comes out the defrost vents. no apparent vacuum leak. all air doors appear operational.

Why would you try to get heat while in A/C mode?!?!?!

There is a vacuum leak somewhere causing the other problem. On my phone right now and don't have the vacuum schematic but it's on here numerous times. Hardermods is the member I got it from and fixed the exact issue you describe.

On my 97, the snowflake doubles as an a/c mode and body panel mode for heat, temp adjusted by the slider.

Running the compressor (snowflake) takes the humidity out of the air. It won't make your air any colder if you are using the heat.

IIRC isn't it also the only way to get air to blow out the top and bottom vents? I think that's how my 02' is set up. Never really understood that. Although I only use the heat when my girl is riding with me lol
