I have a 2011 Chev cruise and when anything is turned on with the heater or a/c, the fans cycle on/off on very high speed for 10 seconds, off for 5, then back on again. I have seen this with A/C, but with the defrost on or heater on or just outside air coming in. When the blower motor is running on anything in the climate control, the fans will do this. I just noticed this within the last few months as we owned this since 2011 brand new, Out of normal warranty- just power train left. Anyone help please? Its getting cold and my wife drives this to work and she is now worried about turning the heat on because the fans are so fast and lout and come on/off all the time. This is not normal in heater mode. Engine temperature seems normal and it could be when we first start the vehicle, so its not a over heating issue. Please Help...

If your talking about the engine cooling fan, I'm pretty sure it comes on with the AC setting always(the defroster also uses the AC). If the fan is running at full high speed might be an indication your coolant is low, did you check the surge tank level?

:iagree: with spacedout! What does your water temp gauge show.

Sounds like the resistor pack isn't working properly. Check out these videos from South Main Auto on youtube.
