My son has a 91' S-10 with a bad ignition switch. Can anyone tell me of the correct procedure for repacement?

 

Get a Haynes manual for the truck, it should give you the instructions you need.

 

REMOVAL & INSTALLATION

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.
   NOTE: 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.

4. Remove the ignition switch-to-steering column retainers, then remove the assembly. To install:
5. 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).
   NOTE: 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.
6. 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).
   NOTE: When installing the ignition switch, use only the specified screws since over length screws could impair the collapsibility of the column.
7. Raise the column into position and secure, then install any necessary trim plates.
8. Make sure the ignition is OFF, then connect the negative battery cable.
