In Reply To Heater doesn't work. Set to 90, AC is visibly operating... posted by thumper300zx on October 21, 2019 at 11:38 PM
     
Message I think I understood it all ok. Did not see any issues. No trouble codes (everything said 50?). All the vent modes work and the temperatures seem to read fine (so it's not getting a false reading from the upper thermostat.

It was blowing ice cold set to 90, but of course, it is cold right now. I did notice this time, however, if I had it set to 90, it was trying to make appropriate vent mode adjustments.

So, I guess it's either the heater core or the blend motor/flap. I will see if I can move that manually to see if heat starts working.
