CarFactBook Diagnostics V2.3

Start with what the car is doing.

Choose a symptom and, when possible, an exact vehicle code. Work through structured observations first, then compare them with reviewed owner evidence. CarFactBook does not invent a diagnosis or rank a failed part from unsupported anecdotes.

Structured checks

Work through observations, not guesses

0/2 checked
Check 1

Does the cabin blower move air at the selected fan speeds?

No airflow and warm airflow are different symptoms and should not be diagnosed as the same fault.

Check 2

Is airflow present but not becoming cold?

This records the actual symptom without assuming refrigerant or compressor failure.

These checks organize observations and safety decisions. They are not a substitute for manufacturer service procedures or a qualified diagnosis, and CarFactBook does not assign a failed part without supporting evidence.
