2004 Chrysler Pacifica no heat
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.

2004 Chrysler pacifica with no heat. I have checked the antifreeze and it is fine. Blower works but just blows cold air. I see two hoses going into the dash from the engine compartment and they are warm, not hot, but just warm. I also noticed when I press the recirculate button it just flashes three times and goes off. any guidance would be appreciated
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.
