Question about Suzuki Aerio SX
Try replacing the ect sensor. If the ect sensor is faulty it will cause the light to read faulty and it also tells your fans when to come on. I own a 2004 suzuki aerio and am a mechanic so I have been through this and the ect sensor fixed my suzuki.

Put your heater on and see if hot air comes out if not the heater core is probably clogged. you could get them to change it and its costly or bypass the heater core and just connect your coolant lines together which will mean no hot air. make sure you drain the coolant first. Or try to force flush the heater core to get it unclogged then after all that put coolant in. If thats no it, run a pressure test on your radiator cap and see if it falls between the proper specifications for a good cap. Right now my suzuki too is overheating and I'm gonna try and bypass the heater core.
