Stuck thermostat. This is covered under the power train warranty.
Cruze, Fan Is Extremely Loud At All Times
This morning I started my 2013 Chevy Cruze and noticed the fan was very loud. It was on the highest speed, like my car was too hot. I looked at the temp on the dash and it was okay, not hot at all. I then noticed the check engine light was on. After that, I noticed the A/C was not blowing cold. For the record, the heat works just fine. The codes that were pulled were the P00b6 and the P00B4. Meaning, radiator coolant temperature sensor issue. If the A/C doesnt work and the heat does work. Does that mean the thermostat is stuck open? What are your thoughts on the issue? Thanks in advance!

It sounds like a defective sensor or wiring to the sensor. Since the ECU can not get a good temp reading, it will default to high fan speed and no a/c.
Without having the book at hand, that's my vote at well. A suck thermostat wouldn't come into play until the engine warmed up and the ECU noticed that it couldn't cool the engine.It sounds like a defective sensor or wiring to the sensor. Since the ECU can not get a good temp reading, it will default to high fan speed and no a/c.
But a bad sensor would be a problem from the get-go. The ECU is playing it safe since it doesn't know what's really happening. If you're under 36,000 miles, then your B2B warranty should cover it.
Appreciate the help! Just looked at the powertrain warranty and looks like sensors are excluded in the warranty. Lame. I will update this post after I get repairs done tomorrow. Thanks again!
P00B6 indicates that the sensor is open. P00B4 indicates that the radiator temp is way off from the engine temp.
It might be worth looking at the radiator temp sensor. It's on the side of the radiator, on the passenger side, about mid-way.

My cruze had the same problem. Very easy fix by the dealer. I missed the sound of the jet though. That's how it sounded.
