Need to change headlight bulbs

Hello,

it's easier to change the light bulbs in this car than in a lot of other vehicles. The 2008 pontiac Grand Prix uses separate bulbs for low beams and high beams. The low beams are located on the outer edge of the headlight assemblies while the high beams are located on the inner edge of the assemblies.
To replace the low beam of the headlight bulb You will be in need of these instruments(Soft blanket or towel, Latex gloves, 9006 replacement headlight (low beam)), please follow the steps below:

1. Open the hood to the 2008 Pontiac Grand Prix after making sure the headlight switch is in the off position, and the keys are not in the ignition.
2. Approach the headlight assembly with the spent headlight in it, and locate the retaining bracket (white) holding the assembly to the frame rail of the Grand Prix.
3. Lift the retaining bracket up about a quarter of an inch in order to align the notches of the bracket to the riveted tabs on the frame.
4. Pull the assembly forward away from the front of the car starting with the inner corner of the assembly toward the grill. Keep in mind the wire harness connection is still attached to the assembly, so only pull it far enough to reach behind and disconnect the plug located at the bottom of the assembly.
5. Place the headlight and bulbs assembly lens down onto a soft towel or blanket.
6. Disconnect the respective low beam or high beam wire harness.
7. Turn the plastic base of the headlight counterclockwise a quarter turn to align the retaining tabs with the release notches. Remove the headlight from the headlight assembly.
8. Put on latex gloves before handling the replacement low beam or high beam headlight. Oil from skin will compromise the life of the headlights if it contacts the glass bulb.
9. Insert the new bulb into the assembly by aligning the retaining notches to the release tabs, and then turn the base of the headlight 1/4 clockwise to lock it into the headlight assembly. Reconnect the harness to the headlight.
10. Bring the assembly back to the Grand Prix and reconnect the main wire harness at the bottom of the assembly.
11. Align the guide pins at the back of the assembly to the locating holes in the front frame rail starting with the outer guide pin first and the inner (toward the grill) guide pin last. Lift the assembly upward while pushing back on the lens to push down on the retaining bracket.
12. Place the key in the ignition and turn the key to accessory power.

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.

there are two L shaped metal rods/brackets that you pull out to remove the whole headlamp assy. dont touch the glass bulb with your hands. the oil from your hands can ruin the bulb or shorten the life.

A loose ground wire to the headlight will keep it dim,Or a headlight adjustment will bring the headlight up.If you can have your headlight turned on a garage door or something at night,and then watch as you change your headlights from low beam to high beam which ones are higher.the last thing to verify is that your high beam headlights are not the plastic lens type that turn dull which cuts the light power.

You need a 9007 bulb

In order to change the bulb, just loosen/remove the two bolts holding the entire light assembly in (side marker, headlight and turn signal) Once these bolts are removed the entire assembly will shift / slide out away from the center of the vehicle. Once the assembly is removed you will have access to the wires/bulb.

Upside down L shaped bracket that is bolted to frame just behind headlight assy. Unbolt bracket, lift bracket straight up to unlock headlight assy. Headlight assy should easlier fall forward to replace any of the 3 bulbs

Those metal wire clips can be a bit tricky. You need to push in on the clip and gently push it to the side and flip it up. Good luck.

check evap vent solenoid alot stick on these cars.

You get to it from the engine compartment. The is a retainer that you simply twist to remove the old lamp. The old lamp will be able to be pulled apart from the wiring socket. Reverse this to install. Type 9007 bulb. Cheapest at Walmart.

inside the engine compartment directly behind the headlight it unscrews and pops out. then put it back in and retighten.
