Service bulletin 68223051A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

HVAC control, Actuator, Power train Control Module MIL light for B104D Blend door circuit low. 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.
