Intermittent dash AC and check engine light FIXED UPDATE
2005 Fleetwood CAT C7. 40k miles
I had posted before about my intermittent dash AC. Would blow cold for between 20 minutes. Refrigerant levels were fine.
I recently had a full service completed by a small independent diesel shop in Deland.
He said it is not uncommon symptom for a bad thermostat. So for about a $100 parts and labor he replaced it. I just did a six hour round trip and had cold AC both ways. I'll keep my fingers crossed.
I was also getting a random check engine light. Gauges normal. Ran fine except it went into limp mode. I bought a Silverleaf setup which reported out of range signal from the turbo boost pressure sensor.
The darn part was $190 and 20 minutes of labor and no check engine light in six hours.
Hopefully good for another 40,000 miles.
