Escalade ESV - Front Headlight Replacement 🔧

Got it—let’s swap the front headlight assemblies on your Platinum. Quick questions before we start:

  • 🧩 Are you replacing the entire headlight assemblies, or just the low/high beam bulbs?
  • 🛠️ Do you have factory LED headlights (Platinum trim usually does)? LEDs are integral to the housing and require full assembly replacement.

Can you confirm if your headlights are factory LED (Platinum usually) or halogen?

Escalade ESV - Front Low/High Beam Service (Factory LED) 💡

On the Platinum, the low and high beams are factory LED modules that are built into the headlamp. They are not serviceable like halogen bulbs. GM’s procedure is to replace the entire headlamp assembly if a low/high beam has failed.

What this means 👇

  • 🔧 To fix a dead low or high beam on your Platinum, replace the complete headlight assembly (left/right as needed). The LED driver (ballast) is integrated and matched to the housing.
  • 💡 The only front bulbs you can replace individually are typically the turn signal/park (PY24W) and some marker bulbs. The low/high LED is sealed.

Parts and Specs 📦

  • 🧩 Headlamp assembly (with LED low/high, DRL, and module):
    • Left (driver): GM 84389114 (superseded numbers may apply)
    • Right (passenger): GM 84389115
    These supersede earlier 23406177/23406178 used on early builds.
  • 🔩 Fasteners: reuse OE bolts; typical sizes 10 mm hex/7 mm hex and Torx T15 for upper trim.

Tools You’ll Need 🛠️

  • 🔧 1/4" and 3/8" drive ratchets and extensions
  • 🔧 Sockets: 7 mm, 10 mm, 13 mm
  • 🔧 Torx drivers: T15, T20
  • 🔧 Trim clip tool (a forked pry tool to pop plastic clips)
  • 🧰 Plastic pry tools (to avoid scratching painted trim)
  • 🔦 Work light and fender covers

Safety First ⚠️

  • 🧯 Disable the automatic headlamps in the infotainment or switch to Off so lights stay off while unplugged.
  • 🔋 Disconnect the negative battery cable (10 mm) to protect the LED driver. This prevents short circuits.
  • 🧼 Use gloves; do not touch LED emitters or optical surfaces.

Removal - Front Bumper Fascia Tip-Out Required 🚗

You don’t fully remove the bumper; you loosen and tip it forward to clear the headlamp tabs.

  • 🧱 Upper radiator cover:
    • Remove push pins across the cover using the trim tool.
    • Lift cover off.
  • 🧱 Upper grille/bumper fasteners:
    • Remove the series of 10 mm bolts along the top of the grille/fascia.
  • 🧱 Wheelhouse fasteners (both sides):
    • Turn wheels for access. Remove 7 mm screws and T15 screws at the liner edge where it meets the bumper.
    • Gently unclip the bumper side retainers by pulling outward at the corner. Support the fascia so it doesn’t drop.
  • 🧱 Lower splash shields:
    • From below, remove a row of 10 mm bolts and push pins at the lower edge of the bumper.
  • 🧱 Tip the bumper forward:
    • With corners released and lowers out, gently pull the bumper/grille forward 2–3 inches. Use a helper or support stand.
    • If equipped with front park assist/fog harness, do not overstretch the wiring. You can unplug the main connector at the LH side if needed (gray latch).
  • 🧱 Headlamp removal:
    • Remove the upper 10 mm bolts (2) and the side 10 mm bolt accessed with the bumper tipped.
    • Slide the headlamp forward to release the locating pins.
    • Unplug the main multipin connector: lift the red CPA tab, then swing the lever to eject.
    • Remove the lamp.

Installation 🔄

  • 🧩 Position the new headlamp; plug in the main connector and lock the lever, push down the red CPA.
  • 🔩 Seat alignment dowels, install bolts finger-tight, then torque:
    • Headlamp bolts: 5–7 N·m (44–62 in-lb)
    • Upper fascia/grille bolts: 7–9 N·m (62–80 in-lb)
    • Lower fascia bolts: 7–9 N·m (62–80 in-lb)
  • 🧱 Re-engage bumper side clips, reinstall wheelhouse screws and lower fasteners, then the radiator cover push pins.
  • 🔋 Reconnect the battery negative.

Aim and Calibration 🎯

  • 🌙 Park on level ground 25 ft from a wall, fuel half-full, driver weight in seat.
  • ⚙️ Use the vertical adjuster on each lamp (hex socket behind the lamp). Set cutoff just below head height at 25 ft. Horizontal is fixed on this unit.
  • 📟 No scan-tool coding needed on your model; the BCM recognizes the lamp.

Troubleshooting After Install 🧪

  • 🔌 If one side is out: recheck the lever-lock connector and the red CPA tab fully seated.
  • 🧯 If DIC shows “headlamp out”: cycle ignition, check fuses F51UA/F52UA (underhood) and the front lighting harness plug you disconnected.

Escalade ESV - Headlight Assembly Replacement (Both Sides) 🔧

Thanks—both sides, factory LED. Below is the OEM-style procedure with beginner-friendly steps.

Parts You’ll Need 📦

  • 🧩 Left headlight assembly: GM 84389114 (supersedes earlier numbers)
  • 🧩 Right headlight assembly: GM 84389115
  • 🧩 Optional new push-pin clips for radiator cover/undertray (have a few spares)

Tools You’ll Need 🛠️

  • 🔧 Ratchets: 1/4" and 3/8" drive with 3–6" extensions
  • 🔧 Sockets: 7 mm, 10 mm, 13 mm
  • 🔧 Torx drivers: T15, T20
  • 🔧 Trim clip tool (forked pry tool to pop plastic clips)
  • 🧰 Plastic pry tools (to protect paint)
  • 🔦 Work light, fender covers, masking tape (edge protection at bumper/quarter)

Safety First ⚠️

  • 🔋 Disconnect the negative battery cable (10 mm). Protects LED drivers and prevents shorts.
  • 🌙 Set headlamp switch to Off so auto-lamps don’t wake during testing.
  • 🧤 Wear gloves; avoid touching LED optics and reflective surfaces.

Overview: Bumper “Tip-Forward” Method 🚗

You don’t fully remove the bumper. You’ll loosen the top, bottom, and sides, release the corners, and tip the fascia forward 2–3 inches to free the lamp tabs. A helper is very useful.

Removal Steps (Both Sides) 📋

  • 🧱 Radiator cover:
    • Pop all plastic push pins with the trim tool and lift the cover off.
  • 🧱 Upper grille/fascia fasteners:
    • Remove the row of 10 mm bolts across the top of the grille/fascia.
  • 🛞 Wheelhouse edges (both sides):
    • Turn the wheels for access.
    • Remove 7 mm screws and any T15 screws tying the liner to the bumper corners.
    • Gently pull the bumper corner outward to release the side retainer clips. Use masking tape on edges to prevent chips.
  • 🪛 Lower splash shields:
    • From below, remove the lower 10 mm bolts and push pins along the bumper lip.
  • 📦 Tip the bumper forward:
    • Support the center with a box or stand. Pull the fascia forward 2–3 inches.
    • If harness is tight (park sensors/fog), unplug the main front harness connector at the left side behind the fascia (gray lock tab). Don’t overstretch wiring.
  • 💡 Remove headlamp assemblies (one side at a time):
    • Remove the two upper 10 mm bolts and the outer 10 mm bolt revealed by tipping the bumper.
    • Slide lamp forward to release locating dowels.
    • Unplug the main multipin connector: lift red CPA tab, swing the lever to eject.
    • Lift the lamp out.

Install Steps 🔄

  • 🧩 Set each new lamp in place; connect the main connector (lever fully locked, red CPA pushed down).
  • 🔩 Align dowels, install bolts finger-tight, then torque:
    • Headlamp bolts: 5–7 N·m (44–62 in-lb)
    • Upper grille/fascia bolts: 7–9 N·m (62–80 in-lb)
    • Lower fascia bolts: 7–9 N·m (62–80 in-lb)
  • 🛞 Re-seat bumper corners into the side retainers. Reinstall wheelhouse screws and lower fasteners.
  • 🧱 Refit radiator cover and push pins.
  • 🔋 Reconnect the battery negative.

Aim the Headlights 🎯

  • 🏁 Park 25 ft from a flat wall on level ground, tire pressures set, half tank.
  • 🔧 Use the vertical aim screw on each lamp (hex behind lamp). Set the cutoff slightly below head height at 25 ft. Horizontal is fixed.
  • 📟 No scan-tool programming required; the BCM self-recognizes.

Tips & Common Pitfalls 💡

  • 🧰 Keep removed bolts grouped by location. Use labeled cups.
  • 🧲 If a corner clip fights you, warm the fascia slightly with a hair dryer to make the plastic more flexible.
  • 🔌 If a lamp doesn’t power up, recheck the lever-lock connector and underhood fuses F51UA/F52UA.

Estimate & DIY Savings 💵

  • 💲 Typical shop quote in Reno: parts + 2.0–2.5 hr labor. You can save the labor by DIYing.
