How to Fix the Reverse Lights to a 1996 Jetta

Blown reverse light bulbs are the most common reason that your 1996 Volkswagen Jettas reverse lights will not illuminate. At its core, however, the reverse light system is controlled by a simple two-wire switch, called a reverse or back-up switch, attached to the transmission. When the switch fails, it will prevent the lights from illuminating at all. Removing and replacing the reverse switch, while outwardly simple, requires removal of the battery box and air box to provide enough clearance for your tools.

Instructions

1

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

2

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

3

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.

4

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.

5

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.

6

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

7

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.

8

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.

9

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.

10

Reattach the battery box lid and close the Jettas hood.
