Fix It

Open the Quests front door. Adjust the drivers seat as far back as it will go in order to provide yourself with sufficient room to access the under-dash area.

Shine the work light in the drivers foot well so it illuminates the area at the top of the brake pedal arm. Retract the retaining tab on the brake light wiring pigtail with your thumb while gripping the pigtail with your foinger. Pull the pigtail off the brake light switch.

Unbolt the faulty brake light switch from the mounting bracket using a box wrench. Discard the faulty brake light switch.

Set the new brake light switch into the bracket. Bolt it in with the box wrench. Plug the wiring pigtail into the new brake light switch by hand.

Depress the brake pedal and have your helper verify the brake lights work before driving your Nissan Quest.

Park the Jetta and set the parking brake. Let the engine cool for at least one hour.

Open the hood and support it in an raised position, using the hood support rod.

Unclip and remove the battery box cover. Disconnect the cables from the battery, starting with the negative cable followed by the positive cable, using a combination wrench. Remove the battery retaining strap using a ratchet. Lift the fuse box off of the battery, then pull the battery out of the battery box. Unbolt the battery box from the engine compartment using a ratchet.

Squeeze the spring clamp attaching the air box to the intake duct using pliers. Move the clamp away from the air box. Unclip and remove the air box cover, then pull the air filter out of the air box. Unbolt the lower half of the air box using a ratchet. Pull the air box out of the intake tube, then lift it out of the engine compartment.

Look between the right side of the transmission housing and the inner engine compartment wall, directly below the air box mounting point. The reverse switch is located directly below the upside-down L-shaped shift linkage at the top of the transmission housing. Alternatively, the reverse switch is located on the top right side of the transmission housing, if you are working on a Jetta fitted with an automatic transmission.

Unplug the two-pin electrical connector at the rear of the reverse switch. Unscrew the reverse switch from the transmission using an adjustable wrench.

Screw the new reverse switch into the transmission housing by hand. Tighten the switch to 15 foot-pounds, using a crow foot wrench and a torque wrench. Plug the electrical connector into the end of the switch.

Push the air box into the intake tube, then slide the spring clamp into place. Reinstall the lower air box into the engine compartment, followed by the air filter and air box cover.

Reinstall the battery box and battery. Place the fuse box over the top of the battery, then reattach the battery cables, starting with the positive cable followed by the negative cable. Tighten the battery terminal bolts using a combination wrench.

Reattach the battery box lid and close the Jettas hood.

Go to the back of your Chevrolet Optra and open the trunk. Clear the trunk on the side that the broken tail light is on. You want full access to this area.

Move the cloth trunk mat away from the back of the tail light you are fixing. Locate the plastic nuts that are holding the tail light in place. Twist these nuts in a counterclockwise direction until they come all the way off. Use an adjustable wrench if you cannot loosen these with your fingers.

Pull the tail light fixture out. If it gets stuck, you can push on the fixture from the inside of the trunk. Use gentle, but firm, pressure to remove the tail light.

Replace the tail light with a new fixture. Make sure it is in securely. Tighten the plastic nuts in a clockwise direction and replace the cloth trunk mat.

Park your vehicle and turn off the ignition. Open the vehicles trunk and access the brake light assembly and remove the red and yellow plastic cover of the brake lights by unscrewing it using the Phillips-head screwdriver in order to access the light bulb. Set aside the screws as it will be needed later on.

Locate the brake light bulb. It is usually the center bulb of three bulbs located in the area. Unscrew the brake light bulb by pushing it slightly and turning it counterclockwise at the same time. Set it aside.

Clean the area where you removed the bulb with a dry rag. You can also use a steel brush if there is accumulated dirt on the socket. The accumulated dirt can sometimes be the cause of the malfunctioning brake light.

Install a new light bulb on the socket by pushing it slightly and twisting it in a clockwise direction. Make sure the bulb is aligned well and screwed in evenly.

Check the light bulb to ensure it works by turning on the car and asking someone to push on the brake pedal while you go to the back of the vehicle to see if it lights up.

Reattach the plastic cover by inserting the screws in the designated holes and tightening the screws, turning clockwise, using the Phillips-head screwdriver. Put back the brake light assembly at the back of the vehicles trunk.

Remove the brake light cover on the vehicles other side and follow steps 2 to 6 to replace the light bulb.

Verify that the headlight switch is in the "Off" position. Release the trunk latch.

Open the trunk and locate the two retaining screws on the inside of the tail light assembly.

Remove the two screws with a T-15 Torx head screwdriver.

Pull the assembly outward and away from the back of the SC1 far enough to access the wire harness connections attached to the back of the assembly.

Press the lock of the tail light/brake light socket (top center bulb inside the red section of the tail light assembly) and twist the socket counterclockwise 1/3 of a turn then pull the bulb and socket assembly out of the tail light assembly.

Pull the bulb straight up and out of the socket then push in the 3157 replacement bulb. For the 2057 bulb, push slightly downward on the glass bulb and rotate it 1/4-turn counterclockwise to remove it from the socket. Align the small tabs at the base of the replacement bulb to the grooves in the socket and twist the bulb 1/4-turn clockwise (again, pushing slightly downward on the bulb) until it locks into place.
