These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hey man i'm dealing with a very similar issue and not entirely sure what it can be. My best guess is that I need to replace my Heater Control Valve Replacement (Part # 928-574-573-04). My issue is that I'm either getting only Hot Air, and sometimes only Cold Air, no matter what I set the temperature at. If you get any other answers, i'd love to know how you made out.
