It is not too bad on that one. You just remove the column covers. Remove the knee bolster. Disconnect the battery, Remove the key in ignition buzzer switch with a small flat blade screwdriver, by unlocking the tab on top and turning it clockwise. Unplug the 3 wire passlock sensor. Turn the key to the run position and with a small allen wrench there is a hole on top of the lock case. Push down and the lock cylinder will come out. Good Luck

    You do not have to mess with any of the air bag parts. Just the plastic covers where the lock cylinder is. It is really not too hard. If you need to see, I am a GM tech in Texas, send me an e-mail address and I can send info. I am not allowed to publish it online. I can send you GM info. Good luck

This is a common problem for the turn signal switch itself. Try used. You will notice in the instructions to remove the steering wheel. Don't. The removal of the ignition switch is also not necessary. Remove the screws at the bottom of the column where it shows and take a screw driver and pry the other side up to see the 2 screws (torx, or star bits) to remove. This will only take about 20 minutes to perform.

  1. Disconnect the negative battery cable.
  2. Remove the 4 retaining screws from the lower column shroud and remove the upper and lower shrouds.
  3. Remove the 2 retaining screws from the multi-function switch and unplug the 2 wiring connectors.
  4. Remove the switch.

To install:
  1. Install the multi-function switch.
  2. Tighten the 2 retaining screws and attach the 2 electrical connectors.
  3. Install the upper and lower column shrouds. Tighten the 4 retaining screws.
  4. Connect the negative battery cable.

How do I remove the ignition tumbler on a 1992 Explorer?


  1. 1 Open the hood. Disconnect the cable from the negative battery terminal. Peel back the insulator if equipped, and use the wrench to loosen the clamp nut on the negative cable.
  2. 2 Remove the covers on the steering column. Use the screwdriver to pull out the screws, and detach the knee bolster below the steering column. Pull out the screws and detach the lower cover to find the screw for the upper cover; then remove the upper cover in the same manner.
  3. 3 Remove the multifunction switch by pulling out its retaining screw and pushing on the release lever to detach the switch from the column.
  4. 4 Disconnect the ignition switch's electrical connector. Then detach the switch from the steering column by pressing on its clips to release the tabs.
  5. 5 Install the new ignition switch in the old one's place, making sure the locking tabs activate and the spring under the switch is in position on the column's locking rod. Connect the electrical connector.
  6. 6 Reconnect all other parts on the steering column in reverse order of removal. Replace the negative battery cable.
  7. 7 Insert your ignition key to test for proper operation in all three positions: "Lock," "Accessory" and "Start."

How do i remove the steering column cover to get at the ignition tumbler on a 1993 dodge dakota


CAUTION Disconnect and isolate the negative (ground) battery cable. This will disable the air bag system. Failure to disconnect the battery could result in accidental deployment and possible personal injury. Allow the system capacitor to discharge for two minutes then begin air bag system component removal. To install:
  1. Engage the electrical connectors to the ignition switch and make sure the switch locking tabs are fully seated.
  2. Before attaching the ignition switch to a tilt steering column, the transmission shifter must be in the PARK position. Also the park lock dowel pin and the column lock flag must be properly indexed before installing the switch as follows:
    1. Place the transmission shifter in the PARK position
    2. Place the ignition switch in the LOCK position. The switch is in the lock position when the column lock flag is parallel to the ignition switch terminals.
    3. Position the ignition switch park lock dowel pin so it will engage the steering column park lock slider linkage.
    4. Apply a light coating of grease to the column lock flag and the park lock dowel pin.
  3. Place the ignition switch against the lock housing opening on the steering column. Ensure that the ignition switch park lock dowel pin enters the slot in the park lock slider linkage in the steering column.
  4. Install the retaining bracket and ignition switch mounting screws, then tighten the screws to 22-30 inch lbs. (3-4 Nm).
  5. If the vehicle is equipped with a tilt steering column, install the tilt lever.
  6. With the key cylinder and the ignition switch in the LOCK position, insert the key cylinder into the ignition switch until it bottoms.
  7. Insert the ignition key into the lock cylinder. While pushing the key cylinder in toward the ignition switch, rotate the ignition key until the end of travel.
  8. Install the retaining screw into the bracket and lock cylinder. Tighten the screw to 22-30 inch lbs. (3-4 Nm).
  9. Install the steering column covers, then the tilt lever, if equipped.
  10. Connect the negative battery cable.
  11. Check for proper operation.

Cant get key switch out of housing, on a 1974 chevy pick up.Trere are no screws or clips visible.


If you mean remove the ignition tumbler from the steering column, you will have to remove the steering wheel and lock plate, then you will need to remove the turn signal lever and screws, and then pull the turn signal switch up and out of the way, you should then be able to see the housing for the ignition tumbler down in the steering column. Look at the tumbler housing and there should be a small slot towards the end of the housing that you can put a small standard screwdriver into and depress a locking latch that is built into the tumbler. When this latch is depressed you will be able to pull the ignition tumbler straight out of the column.

Need to remove ignition switch in my 1986 cutless to put new one in. how do I remove the old one.


Removal & Installation
NOTE This is an extremely difficult and lengthy procedure. You must remove the steering column from the vehicle and disassemble major portions of it. Because the column is collapsible in an accident, it is necessary that it be handled with care to avoid distortion of major parts. It must not be dropped, hammered on or even leaned on, or vitally important parts may deform. The procedure for replacing the ignition switch on tilt type columns is not included here because it involves substantial additional work and the use of several expensive special tools. Unless you are rather experienced, we recommend that the job be left to a competent professional mechanic.

  1. Disconnect the negative battery cable. Remove the clamp bolt from the steering coupling at the lower end of the steering column shaft (located near the steering box, under the hood).
  2. Disconnect the shift linkage from the shift tube lever at the lower end of the column.
  3. Remove the steering wheel with a puller, as described above.
  4. Remove the left sound insulator and lower column cover.
  5. Remove the trim cap or lower trim panel from the instrument panel, depending on equipment.
  6. Remove the steering column cover and toe-pan attaching screws. Remove the shift indicator needle from the shift bowl.
  7. Securely support the column in position and remove the two nuts attaching the column to the underside of the instrument panel.
  8. Lower the column carefully, being careful to retain any spacers that may have been used in order. Disconnect the wiring. Then, carefully remove the column from the inside of the vehicle.
  9. Begin disassembling the column, removing the lock plate, canceling cam, and turn signal switch. See the "Turn Signal" Removal & Installation procedure above.
  10. Remove the ignition lock and key warning switch as described below.
  11. Remove the spring and bolt assembly, and the associated thrust washer. Then, remove the rack preload spring, switch rack, and actuator assembly.
  12. Remove the upper shift lever spring. Then, remove the gear shift lever bowl.
  13. Remove the shift bowl shroud and bowl lower bearing.
  14. Unhook and remove the dimmer switch actuating rod. Remove the attaching nut and remove the dimmer switch.
  15. Remove the attaching screw and stud and remove the ignition switch, disassembling the actuating rod from the hole in the sliding actuator.

Replacing the ignition switch

To install:
  1. Move the ignition switch sliding actuator all the way to the left (ACC) position. Then, move it two detents (OFF-UNLOCK) position to the right.
  2. Then, position the actuating rod hole in the sliding actuator, and install the ignition switch, stud, and mounting screw.
  3. Install the dimmer switch with its attaching nut tightened only loosely. Then, depress the switch slightly until you can insert a 3/32 in. drill through the hole in the switch housing and slider. Force the switch upward to remove any lash and tighten the mounting screw with the switch in this position.
  4. Put the shifter in NEUTRAL and install the shift lever.
  5. Install the shift bowl shroud and bowl lower bearing.
  6. Install the rack preload spring, switch rack, and actuator assembly. Install the spring and bolt assembly, and the associated thrust washer.
  7. Install the ignition lock and key warning switch as described below.
  8. Reinstall the column into the vehicle. Make sure when assembling the lower and upper dash covers that they can slide on the column. If the bracket which mounts the column to the dash has been removed, install the bolts in this order:
    • Left rear
    • Left front
    • Right front
    • Right rear
Tighten the bolts just snug to avoid distorting the column.
  1. Install the switch connector to the ignition switch. Then, position the column in the body and support it there. Install the lockwashers and nuts for the coupling and tighten them. Then, loosely assemble the nuts fastening the mounting bracket for the column to the lower side of the instrument panel.
  2. Position the lower cover to the firewall and ensure that the cover is lined up by starting the left lower screw. Then, install and tighten the right lower screw. Then, tighten the left lower screw. Finally, install and tighten the two screws that fit into the top of the cover.
  3. Tighten first the screw for the left side of the cover clamp; then tighten the screw for the right side of the cover clamp. Finally, install and tighten the remaining cover screws.
  4. Finally, tighten the nuts fastening the column to the underside of the dash. Reinstall the bolt for the steering coupling clamp.
  5. Install the lock plate, canceling cam, and turn signal switch. See the "Turn Signal" Removal & Installation procedure in this section.
  6. Connect the wiring.
  7. Securely support the column in position and install the two nuts attaching the column to the underside of the instrument panel.
  8. Install the shift indicator needle from the shift bowl. Install the steering column cover and toe-pan attaching screws.
  9. Install the trim cap or lower trim panel to the instrument panel, depending on equipment.
  10. Install the left sound insulator and lower column cover.
  11. Install the steering wheel, as described above.
  12. Connect the shift linkage to the shift tube lever at the lower end of the column.
  13. Install the clamp bolt to the steering coupling at the lower end of the steering column shaft (located near the steering box, under the hood).
  14. Connect the negative battery cable and check all column operations for free movement and smooth operation.
