The car has Electronic Auto Temperature Control. When the key is in the run or accessory position the blower fan stays on. The control panel position button is off. What could be the problem staying on?

Good evening,

The blower resistor is the most common issue for this problem.

I attached the location of the resistor and a diagram for you of the circuit.
