The three brake lights are almost certain to be on the same circuit, meaning that if two are working, the third one is likely to be suffering from something as simple as a blown globe. Perhaps the globe is loose in its socket, but if two out of three are working, then you probably don’t have an issue with the wiring or fuses.

The wiper issue could be to do with the body computer (which controls a huge number of a modern car’s functions) but, equally, could be something as simple as dirty contacts in the switch part of the stalk that controls the wipers. Some contact-cleaning spray into the switch might do the trick.

I’ll assume by 'in' you mean the fan that blows climate-controlled air into the cabin and not the fan that cools the radiator under the bonnet. Like anything else powered by an electric motor, these should be almost silent, although the sound of the actual air rushing through the trunking (heater plumbing) and out through the vents can usually be heard when the fan is running full blast.

The most common causes for this noise to change are a failed bearing in the motor which will also potentially affect its running speed, or something foreign caught in the fan’s blades (leaves and dross from parking under trees is a common cause of this).

Cleaning out the fan’s trunking and/or replacing the fan is the solution, but in some cases, this involves fairly major disassembly of the car’s dashboard and a huge labour bill.

The most problematic of the Cruze transmissions were the six-speed automatic fitted to Cruzes built between 2011 and 2013. Holden actually instituted a special repair program for owners of these cars and extended the warranty period on those that had been repaired under the terms of that program.

The 2015 car you’re looking at should not have these problems, but the Cruze itself was plague by a long list of other faults including oil and coolant leaks, overheating, cracked cylinder heads and more. To be fair, the later the build date, the less likely the problems were to occur, but any Cruze needs a careful, independent inspection before money changes hands.
