Volkswagen produced the MKII or Type 2 Jetta between 1984 and 1991 and it was for many years the best-selling European car in North America. The ignition switch engages the starter motor and electronics to allow the engine to start. The switch is located on the steering column and is held in a metal housing attached to the steering shaft.

Instructions

  1. 1

    Disconnect the negative battery cable from the battery with a box or socket wrench. Remove the airbag fuse from the driver side fuse panel.

  2. 2

    Pry off the horn pad with a flathead screwdriver and disconnect its wiring.

  3. 3

    Loosen and remove the central steering wheel nut with a wrench. Wiggle and tap the steering wheel until it slides off of the steering wheel shaft.

  4. 4

    Loosen and remove the screws holding the steering column panels in place with a screwdriver. Unplug the wiring harnesses attached to the switches at the top of the steering wheel shaft.

  5. 5

    Loosen and remove the screws holding the switches in place with a screwdriver and slide the switch assembly up and off of the steering wheel shaft.

  1. 1

    Drill a hole in the ignition switch housing in order to remove the switch. The switch itself inserts into a cylinder in the housing. The hole must be drilled into the side of the housing cylinder 15/31 inch from the top lip of the cylinder and on the side closest to the steering shaft. The hole must be drilled with a 7/64 inch or 3mm drill bit to a depth of 3/8 inch. Do not drill past this as the bit will go into the switch itself.

  2. 2

    Insert a drill bit smaller than 7/64 into the hole you just drilled. The bit will press against a spring clip inside the housing and release the ignition switch.

  3. 3

    Insert the key in the ignition switch and pull the switch from the housing.

  1. 1

    Insert the new ignition switch into the ignition housing and make sure the internal spring clip clicks into place to hold the switch.

    Connect the switch wiring harness by pushing the wiring connector onto the switch connector.

  4. 4

    Attach the steering column covers and tighten their screws with a screwdriver.

  5. 5

    Place the steering wheel onto the steering shaft and tighten the steering wheel nut with a wrench. Connect the negative battery cable and tighten it with a wrench.
