one hot and one cold tube is a clogged heater core as for the ac issue could be the blend air door or motor

I even tried a new used control panel too with no luck. But when I put it in I can hear the doors moving. I think there is heat how but no AC. How do I check the blend door

1. Turn Ignition switch to ON
2) Press both the POWER and RECIRCULATE buttons at the SAME time and HOLD for at least 5 seconds.

3) The POWER and RECIRCULATION lights will flash

4) Calibration should take about about 2 minutes to complete if you have heater control and about 20-seconds if you have Automatic Temp Control system.

5) If lights continue to flash AFTER 3 minutes (manual system) or 20-seconds (Auto system), the control unit has detected a failure. You need a scan tool to pull the trouble codes (Thanks Chrysler). If there’s a trouble code stored, the lights will CONTINUE to flash until the unit completes a successful calibration OR until the vehicle has driven 8 miles.

Default Check thermostat.

I also noticed when I press the recirculate button it just flashes three times and goes off. any guidance would be appreciated
Check the thermostat. It sounds broken like it is always open. The recirculate button is off if it is in defrost mode

a broken or open thermostat has nothing to do with cold or hot air inside the car.

so a constant open thermostat will cool the coolant to less than operating 194 F about 150’s I’m guessing an so the coolant entering the heater core is warm, not hot, so air coming out of is Luke warm as described in the original post.

You can tell with your hand the difference in 150F and 194F heat? Not likely
Plus a broken thermostat would cause the check engine light to come on and give you a coolant temp rationality performance code.
