Hello,

The 2004 grand prix pontiac houses 2 headlight bulbs per headlight assembly. The low beam headlight are located at the fender of the car and the high beam on the grill side of the assembly.

To replace the headlight bulb of Your pontiac grand prix, 2004 model. It is qiute technical and moderately easy to fix. There is no solution that cannot be done the DIY way, as long as You get the proper guide and You are technically able to do such works.

1. Park the Grand Prix on a flat surface, apply the parking brake and ensure both the engine and headlight switches are off.
2. Open the hood and approach the headlight assembly with the faulty headlight bulb.
3. Locate the headlight assembly retaining clip. It's behind the headlight assembly on top on the fender side. Lift the clip upward halfway to release the headlight assembly.
4. Pull the assembly out being careful not to scratch the paint on the fender or the lens of the assembly.
5. Reach behind the assembly and disconnect the wire connection and plug from the headlight bulb socket.
   
6. Turn the socket of the bulb counterclockwise 1/4-turn to remove the composite bulb from the assembly. Discard the bulb.
7. Install the replacement bulb into the assembly (handling the plastic socket part only oil in skin will damage the glass bulb of halogen bulbs because of the intense heat they burn at), but ensure the tabs of the socket end of the bulb are aligned with the notches in the assembly before turning it clockwise and locking the bulb into place.
8. Plug the wire connection back into the socket of the bulb before replacing the assembly back into place and pushing down on the retaining clip. Test the headlight bulb for operation before closing the hood.

Hope this was helpful. Thank You for using FixYa!!!

Trying using a lens renewal kit and a brighter bulb. Like a Xenon.

Hi,

Replacing a headlight on a Toyota Matrix is a simple process that only requires the use of a screwdriver and a replacement bulb. The Matrix uses 9006 bulbs for the low beams and 9005 bulbs for the high beams. Headlight bulbs can be purchased at auto parts stores.
Replacing Low Beam Bulb

1. Turn off the engine of the Matrix and open the hood
2. Rotate the bulb base in the headlamp assembly counterclockwise to remove the low beam bulb. Unplug the electrical connector. If the connector is too tight, wiggle it slightly to help remove it.
3. Install a new bulb into the connector and place it into the assembly. Rotate it clockwise to lock it into place. Close the hood.

Replacing High Beam Bulb

1. Turn off the engine of the Matrix and open the hood. If replacing the left-hand headlight, remove the air cleaner duct by removing the securing clip with a screwdriver and pulling the duct out of the vehicle.
2. Turn the bulb base counterclockwise to remove it. Unplug the electrical connector.
3. Install a new bulb into the connector and place the bulb into the assembly. Rotate it clockwise to lock it into place. Reattach the air cleaner duct if replacing the left-hand headlight. Close the hood

I hope this helps.

Best regards.

Lift hood, at top of each headlight assembly look for two L-shaped tabs. Pull these tabs straight up, this will release the headlight assembly. Lift assembly forward to gain access to rear of assembly. There two rubber caps, the top one is for access to the low beam and the bottom for the high beam bulbs. Remove the appropriate cap, grasp bulb socket and turn CCW to release. Unplug bulb from socket by releasing catch on side of socket, install new bulb, DO NOT touch bulb glass with fingers. Reverse steps to re-assemble.

If you have the HID bulbs, and there is moisture in the bottom of the assembly, the high voltage box at the bottom will not work. this requires removing the whole headlamp, removing the circuit board from the bottom and drying out. I have done mine twice before finally finding how water was getting in at the top seam of the lamp assembly. You will have to dis-assemble part of the wheel well and bumper cover to gain access to all the mounting bolts. Best of luck

First face the vehicle so the battery in on the right.
Second open hood.
Third Remove the Grill by pushing firmly on two retainer clips that are on the top, use the wide slot screwdriver to get the rest of the clips off. Pull up gently on the grill it should then pop out. The grill extends under each headlight assembly any other retainer clips should release when the grill in popped out.

Step 2 Fourth on top of the headlight assembly you will see one 1" tab on the right and left side, pull the tabs upward about two inches and this should release the headlight assembly. You then should be able to pull the headlight assembly out toward you.

Step 3 Finally at the back of the headlight assembly you will see two rubber caps one for low beam and one for high beam, the white base is for the low beam and the black base is for the high beam. Unsnap the wire harness from the bulb base, turn the bulb clockwise.

Replace the bulbs high beam on the outside and low beam on the inside.

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.
