How to Replace the Headlight in a 2002 GMC Yukon Denaliby Leonardo R. Grabkowski
The headlights in your 2002 GMC Yukon Denali are very simple to replace, requiring no tools. This should take a mere five minutes of your time. Headlight replacement is the same in all Yukon models sold from 2001 through 2006 and will also work for the Chevrolet Tahoe.
Open the hood and look at the top portion of the headlight assembly to find the retaining pins. Each headlight assembly has two pins.
Twist the outer pin outward, then pull it up. Twist the inner pin inward, then pull it up.
Pull the headlight assembly from the front of the Yukon. Examine the rear of the assembly to find the low-beam and high-beam headlights. The high-beam headlight is the outside bulb module; the low-beam light is the inside bulb module.
Unplug the connection from the bulb you must replace. Twist the bulb module counterclockwise. Pull the bulb module out.
Insert the new bulb module. Hold it by the plastic piece to avoid damaging the bulb. Twist it clockwise to lock it. Plug in the connection.
Reinsert the headlight assembly into the cavity. Attach both pins and tighten them.
- Don't touch the glass part of the new bulb. The oils on your skin can cause them to prematurely burn out.
