The Sedona is the Korean-automaker Kia's first entry into the minivan market. The Sedona debuted in 2002 and was redesigned for the 2006-model year. The Sedona's headlights are typical H7 halogen bulbs, which are not difficult to replace, although removal of the entire headlight unit is necessary to access the headlight bulbs. The procedure is the same for all second-generation Kia Sedona models, 2006 to 2010. It may be slightly different for first-generation (2002 to 2005) models.
Open and support the bonnet. Find the three bolts that keep the headlight mounted in place. One bolt is on the top-outboard corner. The other two bolts are in the front-inboard corner, close to the centre of the grille.
Remove each bolt with a 10mm socket wrench. If the bolts are difficult to remove, spray them with a bolt lubricant such as Liquid Wrench or PB Busters.
Attempt to pull the headlight out. Start in the inboard corner. There is an additional stud between the mounting frame and the headlight. If you cannot pull the headlight out with your hands, use a large flathead screwdriver to push outward against the rear of the headlight. This should release it from the stud.
Unplug the harness from the back of the headlight. Bring the headlight to a table or work station.
Twist off the plastic cap to view the bulb. Squeeze the outer tabs on the bulb socket and pull it out. Insert the new bulb in its place, holding it by the metal trim on the bottom. Avoid touching the glass. If necessary, wear gloves. The tabs will lock to secure the bulb.
Bring the headlight back to the Sedona. Attach the wiring harness to the rear. Re-insert the headlight into its mount. Push it firmly to re-engage the stud. Tighten the three 10mm bolts.
