Hi. Here is a guide to help you with the bulb exchange.
1.- First turn the ignition off, next open the trunk, you will noticeon each side to the left and right next to the light case 2 plasticscrews, some older models might have regular screws, they secure thelight case to the body of the truck
2.- Let's start with the left side, the plastic screws will have anopening on the side, make sure they are facing you and when you putthem back make sure they'll face you too, insert the flat thinscrewdriver into the opening and push up with not much force in such away that you'll be able to pull it out with your own fingers, just usethe screwdriver to push up a little bit and finish by pulling it outwith your fingers.
3.- Remove the 2 crews while holding the light case, remove the lightcase with care, you'll notice that it will be attached to the body by 2plastic pins, they'll will come out by pulling the case out do not usetoo much force, hold the case with both hands and make yourself comfortable
and when you're ready pull, try little force first and increase it as needed, this is to avoid damaging the parts.
4.- Once is out look at the wiring at the back of the light that holdsthe light bulb, you'll have to turn it counterclockwise a little to beable to retrieve the bulb, turn first and then pull out with care,remember when changing the bulbs not to touch the new bulb itself withyour fingers it may shorten the life of the bulb if you do so, pull outthe bulb, insert the new one.
5.- For the other side follow the steps from 2 to 4.
6.- Now just follow the instructions in reverse to put back all thepieces, insert the socket, turn it clockwise, make sure it's secure,hold the light case with both hands looking that the pins are alignedto their openings, push them back make sure they are in and finallysecure the case to the body with the plastic screws, remember that theyhave to face you so it'll be easier to remove for any future light bulbchanges.
Please rate and god bless.
