How to Replace the Headlight in a 2002 GMC Yukon Denali

by 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.

Step 1

Open the hood and look at the top portion of the headlight assembly to find the retaining pins. Each headlight assembly has two pins.

Step 2

Twist the outer pin outward, then pull it up. Twist the inner pin inward, then pull it up.

Step 3

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.

Step 4

Unplug the connection from the bulb you must replace. Twist the bulb module counterclockwise. Pull the bulb module out.

Step 5

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.

Step 6

Reinsert the headlight assembly into the cavity. Attach both pins and tighten them.
