The HVAC temperature door feedback voltage is monitored by the PCM. If the PCM detects a loss of voltage from the HVAC Temperature door it may set a B104D in the PCM. If B104D is set in the PCM and no faults are found in the HVAC module, proceed with the following actions:~ 1- Inspect the HVAC C1 Pin2 for 12 volts B+. if no voltage is found repair the short or open in the A937 circuit. ~ 2- If voltage on Pin2 is normal (12 volts B+), clear the DTC.~ 3- Confirm That DTC B104D Does not return after Calibration~ There are no HVAC components that need to be changed.
