How do you change heater control illumination lamps on a ford KA mk2?

To change the heater control illumination lamps on a Ford KA MK2, first, ensure the vehicle is turned off and the key is removed. Remove the center console trim by carefully prying it away from the dashboard, taking care not to break any clips. Once the trim is off, locate the heater control unit and disconnect the electrical connector. Finally, replace the burnt-out bulbs by twisting them out of their sockets and inserting new ones, then reassemble everything in reverse order.
