Question about 2004 Hyundai Elantra
2004 elantra heater control only operates at # 4 setting.
If # 4 is the highest fan setting it might be the resistor pack that controls the fan speeds.For each speed increase the fan switch takes a resistor out of the resistor loop The highest speed is a direct connection to the battery. The switch is usually located very close to the fan since it gets quite hot and needs to be cooled by the fan.It is also generaly accessible from under the hood,but not always.Sometimes it is under the dash Hope this helps.

The Fan control Knob on you heating system needs to be replace. The only problem is that it comes in one piece. There is a resister inside of that switch that controls the fan sppeeds and it shot, so you need to rplace the heating/ Cooling control unit. Good Luck
