🔧 Enclave - Headlight Bulb Replacement

On your Enclave, the exact replacement method depends on which headlamp system you have. Some versions use replaceable halogen bulbs, while others use HID/LED components that aren’t simple “bulb swaps.”

Difficulty Level: Beginner to Advanced | Estimated Time: 0.5-2.0 hours

⚠️ Safety & Precautions

• ⚠️ Turn lights OFF and let the headlamp area cool before touching anything.
• ⚠️ Never touch a halogen bulb’s glass with bare fingers; oil can shorten bulb life.
• ⚠️ If equipped with HID, the system can carry high voltage—do not open igniters/ballasts.
• ⚠️ If you’ll work near the radiator fan area, keep the key away so the fan can’t start unexpectedly.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify what you’re replacing (quick check)

• Turn the headlights on and confirm which lamps are out: low beam, high beam, or both.
• Look at the headlamp housing: if it’s labeled LED or HID, the “bulb” may not be a simple replaceable halogen bulb.
• Tell me what the housing says.

Step 2: Access the rear of the headlamp (common access path)

• Use a flashlight to locate the rear cover(s) on the back of the headlamp assembly.
• If an air intake duct or cover blocks access, remove its fasteners using a 7mm socket and/or a trim clip removal tool.

Step 3: Remove the dust cover (if equipped)

• Twist the round dust cap counterclockwise by hand and remove it.
• If it’s tight, use nitrile gloves for better grip.

Step 4: Disconnect the bulb electrical connector

• Press the connector tab and pull straight back.
• If it’s stubborn, gently work it off by hand—don’t pull on the wires.

Step 5: Remove the bulb (halogen style)

• Twist the bulb counterclockwise and pull it straight out.
• Keep note of the bulb’s alignment tabs so the new one seats the same way.

Step 6: Install the new bulb

• Wear nitrile gloves and insert the new bulb without touching the glass.
• Twist clockwise until fully locked.
• Reconnect the electrical connector until it clicks.

Step 7: Reassemble and repeat on the other side

• Reinstall the dust cover by hand (twist clockwise until snug).
• Reinstall any ducting/covers using a ratchet, extension (3 in), and 7mm socket.
• Repeat Steps 2–6 on the opposite headlamp.

Step 8: Function check

• Turn the headlights on and verify low beam and high beam operation.
• If you disconnected the battery, reconnect it using a 10mm socket.

✅ After Repair

• Confirm both sides match in color and brightness.
• If one side still doesn’t work, swap the new bulb side-to-side to rule out a bad bulb.
• Make sure dust caps are sealed to prevent moisture inside the headlamp.
