If adjusting the fan speed knob does not change the speed, the resistor controlling the fan speed is likely damaged. To replace this resistor, access the air duct located just behind the glove compartment.

Unscrew the screws along the lower edge of the compartment to open the door and unscrew those along the upper closure line to completely remove it. Next, locate the resistor next to the fan, disconnect the power connector, and rotate the resistor to release and extract it.

How to reset the tyre pressure warning light on the Kia Niro EV?

To reset the tyre pressure warning light on the Kia Niro EV, inflate the tyres until they reach the correct pressure value. This value is indicated on the sticker attached to the driver's door pillar. Once the tyres are inflated, turn on the instrument cluster to check that the warning light has completely disappeared from the display. If it is still present, you may need to drive for a few miles to ensure it disappears completely from the screen.
