Front Fog Light Bulb

REMOVAL


1. Locate back cover on fog lamp assembly where bulb is located inside.

1. Remove the back cover.

1. Remove the spring retainer, and then detach the fog light bulb.
2. DO NOT TOUCH HALOGEN BULB!! Oils from skin will cause bulb to explode during operation.
   

1. • 1 Open the hood and reach down into the engine bay for the fog light assembly. If you cannot reach the fog light assembly from the top you may need to get underneath the truck to reach it. Remove the electrical plug running to the fog light ballast.
     
   • 2 Remove the bulb. Unlock the fog light bulb by turning it counterclockwise and pulling it straight out of the assembly.
     
   • 3 Slide a new bulb into the fog light assembly. The part number you will need for the new bulb will be located on the ballast or base of the old bulb.
     
   • 4 Turn the bulb clockwise to lock it into the fog light housing.
     
   • 5 Reconnect the electrical connector to the bulb ballast.
     

the fog light bulb in the 98 Grand Prix is easy pull pigtail off light turn light from back and it will come out , replace is reverse obviously , but make sure the orientation is correct on housing as there is one tab bigger than the other 2 have to look at it from underneath to see orientation of the bulb housing.

2005 Forester - It is easiest to remove the fog assembly.

1. From underneath the vehicle pry out one plastic fastener to be able to bend the light weight plastic mud protector downward. You will see the underside of the fog light assembly with one 10mm bolt directly above you. Remove this bolt.
2. From the front of the vehicle unscrew one 10mm bolt at top of fog light (this is the shorter of the 2 by the way) and pry out one plastic rivet adjacent to it.
3. Carefully remove the fog assembly and disconnect 2-pin power connector by pulling up on the release. Carefully wiggle the housing out (no force req'd).
4. Unscrew the back from the housing and replace H3 bulbs. Take care not to touch the bulb while replacing.
5. Reverse to install.

Should take an hour at most.

if it has an alarm the alarm needs to be diabled

Halogen bulbs are brighter and generally draw more current than standard filament ones.
Have you check that the supply fuse has not popped ?

Hi there! You have to remove the plastic under the car bumper and then slip your hand up there to remove the bulb. On some cars you can remove the 10mm blts that hold the assembly in from the front,then take the assembly out and access the bulb.
