I still have not repaired the GMQ with the No Heat symptom.
The first two codes point to the Blend door 024, 025.
The 51 code is not listed in the diagnostics I found.
The blend door makes it's familar creaking sound as the module commands the door to open and close.
I replaced the blend door module this past spring, I hate this job. :o
