Hyundai Repair: Im looking for the heater control switch on my 99 hyundai elantra, hyundai elantra, fan switch

Question
Where is the heater control switch located on my 99' hyundai elantra?

Answer
The fan switch is located directly behind the knob you turn to regulate fan speed.  The other controls operate via cables running behind the control assembly and the heater box behind the dash.

I'm a little troubled that this seems like an overly obvious answer.  If this isn't what you were looking for, follow-up with additional details.  If you're looking to repair a problem, knowing your symptoms may help me in assisting you.
