I read posts concerning inop HVAC control.
After replacing a dead battery, the HVAC would blow full hot 2 clicks off of cold. Tried recalibration several times with no luck, then I saw mention of feedback voltage being
out of spec. The new battery was 100% top charged but during the cal procedure the fan is on high.
I hooked up a high amp charger to boost system voltage -- problem solved!
