The ignition switch on my 94 Ford Crown Victoria turns freely without stopping at the positions. it starts but will not turn off. What is the problem?


you may not have the rod in the correct position so it pulls and pushes. the key has to push to start and pull the rod back to turn it off. you may have to reinstall the key lock cylinder with the rod in the right place.

1998 ford mustang gt the key in the ignition stuck in on , had to disengage battery why is it doing this and what do i need to do ?


The ignition lock is hooked up to the ignition switch by a rod. I've seen the switch go bad but the connecting rod is plastic and can also break which is what it sounds like happened. You can start the car because the rod is pushed to start but when you try to turn it off it can't pull the rod because it is broken. The fix involves pulling the column apart. It can be dangerous ( the air bag ) and you need some special tools.

Need to replace the entire ignition how to remove the steering out of the way


Ignition Switch - REMOVAL & INSTALLATION
(see Figure 1)
  1. Disconnect the negative battery cable.
  2. Remove the lower column trim panel, then remove the steering column-to-instrument panel fasteners and carefully lower the column for access to the switch.
  3. Place the ignition switch in the OFF-LOCK position.
If the lock cylinder was removed on vehicles through 1991, the actuating rod should be pulled up until it stops, then moved down one detent; the switch is now in the Lock position.

Fig. 1: Adjusting the ignition switch

  1. Remove the ignition switch-to-steering column retainers, then remove the assembly.
To install:
  1. Before installing the ignition switch, place it in the OFF-LOCK position, then make sure that the lock cylinder and actuating rod are in the Locked position (1st detent from the top or 1st detent to the right of far left detent travel).
Most replacement switches are pinned in the OFF-LOCK position for installation purposes. If so, the pin MUST be removed after installation or damage may occur.
  1. Install the activating rod into the ignition switch and assemble the switch onto the steering column. Once the switch is properly positioned, tighten the ignition switch-to-steering column retainers to 35 inch lbs. (4.0 Nm).
When installing the ignition switch, use only the specified screws since over length screws could impair the collapsibility of the column.
  1. Raise the column into position and secure, then install any necessary trim plates.
  2. Make sure the ignition is OFF , then connect the negative battery cable.


Ignition Lock Cylinder - REMOVAL & INSTALLATION
(see Figure 1)
  1. Disconnect the negative battery cable.
  2. Matchmark and remove the steering wheel.
  3. Remove the turn signal switch from the column and allow it to hang from the wires (leaving them connected). For details, please refer to the procedure located earlier in this section.
  4. For vehicles through 1991, place the lock cylinder in the Run position.
  5. For 1992-93 vehicles, remove the buzzer switch assembly.

Fig. 1: Ignition cylinder replacement

  1. Carefully remove the lock cylinder screw and the lock cylinder. If possible, use a magnetic tipped screwdriver on the screw in order to help prevent the possibility of dropping it.
CAUTION If the screw is dropped upon removal, it could fall into the steering column, requiring complete disassembly in order to retrieve the screw and prevent damage.
To install:
  1. Align and install the lock cylinder set. On vehicles through 1991 it will be necessary to rotate the switch clockwise to align the cylinder key with the keyway in the housing.
  2. Push the lock cylinder all the way in, then carefully install the retaining screw. Tighten the screw to 22 inch lbs. (2.5 Nm) on tilt columns or to 40 inch lbs. (4.5 Nm) on standard non-tilt columns.
  3. If necessary, install the buzzer switch assembly.
  4. Reposition and secure the turn signal switch assembly
  5. Align and install the steering wheel.
  6. Make sure the ignition is OFF , then connect the negative battery cable.

> When installing the ignition switch, both the locking mechanism at the top of the column and the switch itself must be in the LOCK position for correct adjustment. To hold the mechanical parts of the column in the LOCK position, move the shift lever into PARK (with automatic transmissions) or REVERSE (with manual transmissions), turn the key to the LOCK position, and remove the key. New replacement switches, when received, are pinned in the LOCK position by a metal shipping pin inserted in a locking hole on the side of the switch.


6. Engage the actuator rod in the ignition switch.
7. Place the ignition switch on the steering column housing and loosely install 2 retaining nuts.
8. Move the switch up or down along the column to locate the mid-position of the actuator rod lash, then tighten the retaining nuts to 47-64 inch. Lbs. (5-7 Nm).
9. Raise the steering column into position at instrument panel. Install steering column shroud.
10. Connect the negative battery cable.
11. Remove the locking pin, connect the battery cable, and verified that the engine will only crank in PARK and NEUTRAL. Also check to make certain the start circuit cannot be actuated in the DRIVE and REVERSE positions.

Key turns to the on position but does not do anything. i changed the lock cylinder but it does the same thing 1989 ford truck


The lock rod actuator may be broken. Check to see if the rod going to the ignition switch moves . The steering column will have to be disassemble if the rod is broken.

1985 ford F150: Turned key to start my truck, and felt something go "crunch". I removed the steering wheel and the lock mechanism in the steering column. All looks fine. Do you have any idea what could...


It may be the 'actuator'. It is a rod that connects the lock cylinder to the ignition switch on the tilt wheel units. It is made of aluminum and often breaks as things become worn.
