Borrowed this from another....hope it helps........
access area inside the wheel well forward of the tire. The back side of the headlamp assembly is hidden by a rubber flap that's fastened to the fender liner with two-piece push-on plastic pins. I turned the wheels to the right to get at the passenger side, to the left for the driver's side, as you can see in this pic of that area with the flap in place.
Another forum member noted that jacking the car to raise the wheel well relative to the wheel provides more room to work. I have small hands and was able to complete the job without using a jack.
You only need to remove the outer three plastic pins that are marked in the photo above to be able to fold the flap out of the way and see the back of the headlight assemby and the DRL wiring and socket. This pic was taken at the best angle I could find, but it is still hard to see the socket - shown by the arrow:
I used a pair of diagonal cutters to pull out the center pin of the fasteners to release them, taking care not to cut the pins.
The socket must be turned about 30 degrees counter-clockwise to release it from the assembly. When released the socket can be pulled straight back out of the assembly. This pic shows the socket released and turned so you can see the rear of the socket; a release tab, discussed below, is marked with an arrow.
The bulb has a bayonet type connection and is removed by pulling it straight out of the socket
There are two keys to getting to the bulbs.
1. The wiring harness to the bulb socket is too tight on the driver's side to allow the socket to be rotated counter-clockwise. The wiring is clamped to the car just a few inches away from the socket. I was able to firmly, but carefully, tug on the wiring and pull enough slack from the clamp to allow the socket to turn.
2. The sockets must be unlocked before they can be rotated in the lamp assembly. This is done by squeezing a tab on the socket toward the center of the socket while you are turning. The tab is on the side of the socket and is difficult to reach, especially on the passenger side. On that side I used a small flat blade screwdriver in one hand to pry the tab while turning the socket with my other hand.
I think it's a good practice to use some silicone grease on the socket and bulb connection when installing new bulbs. The grease helps transfer heat away from the connection and reduces corrosion.
