Does anyone have any diagnostic methods for the heater control that is on the dash? Just had the heater core replaced and now get warm air not hot. Did the calibration procedure and got hot air for a while but now it is only warm again. It is either the heater control or (I can't bare to think) the blend door actuator. Since the dash was just out I don't want to go through that again and am hoping the control is the issue. Thanks for any help.
