Fix It

Replacing the key cylinder on the steering column of your Jeep Wrangler may be necessary if damage has occurred to the tumblers or pins inside the cylinder. A replacement cylinder is available from the Jeep dealer and can be keyed to use your existing key for a fee. The cylinder can be swapped quickly and does not require a bunch of specials tools to complete.

Instructions

1

Sit in the drivers seat of your Jeep and insert the ignition key into the cylinder. Locate the hole in the bottom panel of the steering column directly below the cylinder.

2

Insert a small screwdriver or punch into the hole in the column and push the pin inside the hole up. Turn the key and cylinder to the "On" position then pull the cylinder straight out of the column. Remove the screwdriver or punch from the hole under the column.

3

Turn the key to the "Off" position then withdraw the key from the cylinder. Insert the key into the new cylinder and turn the key to the "On "position on the new cylinder.

4

Insert the cylinder and key into the column the rotate the key to the "OFF" position. Withdraw the key from the cylinder.

The ignition switch on a 1977 Chevrolet truck is mounted on the steering column and is designed to trigger the starter motor and start the engine. This assembly can wear out over time. You then would have to remove the switch and replace it with a new one. This task can take about 30 minutes.

Instructions

1

Unbolt the steering column from the dashboard with the 1/2-inch ratchet and socket. Caully lower it away from the dashboard to access the top of the ignition switch.

2

Unplug the wiring to the switch. Insert the key in the ignition and put it into the "Lock" position.

3

Unscrew the switch from the column using the Phillips-head screwdriver. Pull the switch off of the column and replace it with a new unit.

Installing a toggle switch into your fog lights electrical circuit allows you to control them remotely. Flipping the switch to the "on" position completes the electrical circuit and allows power to flow from the battery to the lights, while flipping the switch to the "off" position breaks the circuit stopping the flow of electricity. Always remember to disconnect the positive battery cable from your batterys positive terminal before servicing any electrical circuit on your vehicle. Failure to follow that simple safety step can result in painful electric shock and damage your vehicles electrical components.

Instructions

1

Cut the wire connecting your fog lights to their power source using your diagonal pliers.

2

Remove 1/4 inch of insulation from both new ends of the power wire with your diagonal pliers.

3

Connect the wire running to your power source to the "source" terminal of your toggle switch.

4

Connect the wire running to your lights to the "accessory" or "load" terminal of your toggle switch.

5

Cover all exposed conductors with electrical tape.

The 1994 Mustang was a popular performance car with over 120,000 produced by Ford. The Mustang was a two-door, rear-wheel drive car with a solid rear axle. The ignition switch is located on the right hand side of the steering column. Replacement of the ignition switch may be required due to switch failure or loss of the keys. Basic hand tools are required to perform replacement of the ignition switch.

Instructions

1

Open the hood of the mustang and remove the negative battery cable from the battery, using a wrench. Wait two minutes and use the wrench to remove the positive battery cable from the battery.

2

Remove the screws holding the drivers side knee bolster in place. Gently pull on the bolster to remove it from the Mustang.

3

Place the ignition switch in the "Run" position and leave the key in the switch.

4

Remove the plastic panel covering the bottom of the steering column with the Phillips screwdriver.

5

Lift the tab of the electrical connector on the ignition switch and separate the connector from the ignition switch.

6

Remove the two Torx bolts holding the ignition switch to the steering column and pull the ignition switch free of the steering column.

7

Place new switch next to the old unit and verify the actuator pin is in the same position. Insert the new switch into the steering column and attach with the two Torx screws. Tighten the Torx screws with the Torx screwdriver to secure it to the steering column

8

Snap the electrical connection into the new ignition switch.

9

Replace the lower steering column cover and tighten the retaining screws with the Phillips screwdriver. Position the knee bolster into the original position and secure with the Phillips screws.

10

Attach the positive battery cable to positive terminal on the battery and tighten with the wrench. Repeat for the negative battery cable.

Vehicle sensors communicate engine performance information to a cars on board computer. This information can take the form of a diagnostic trouble code, or DTC, like the code described as "Lack of HO2S21 Switch-Adaptive Fuel at Limit."

Identification

The HO2S21 code, also referred to as P1130, is specific to Ford Motor Companys computer codes. It references the failure of heated oxygen sensors, numbered one and two, within the vehicles emissions system.

Meaning of Failure Code

The P1130 trouble code occurs once the heated oxygen sensor, or sensors, fails to switch between reports of a rich or lean oxygen amount vented from the engines combustion chamber. This code points to either a problem with the sensors themselves or a malfunction within the emissions system.

Considerations

The sensors electrical supply may be compromised by water damage to the sensors harness, or a failure of the entire sensor.

In a perfect world, cars, trucks, and automotive components would last forever. But theres a delicate balance between cost and longevity, so vehicle manufacturers constantly push the engineering envelope as it relates to doing more with less. Although the headlight switch for your 2001 Ford F-150 is considered an electrical component, its mechanical aspect is susceptible to normal wear and tear after years of regular use. Replacing the defective headlight switch is easy, requiring minimal hand tools to get the job done.

Instructions

1

Connect a memory saver device to the vehicle, according to the products specific instructions. Although not absolutely needed to replace the headlight switch, using a memory saver will avoid short-term drivability issues after reconnecting the negative battery cable, in addition to saving you the hassle of reprogramming the vehicles stereo and other programmable features that depend on constant battery power. Open the hood and disconnect the negative battery cable with a socket and ratchet.

2

Insert a thin, non-marring plastic pry tool into the gap between the bottom right corner of the headlight switch assembly and the instrument panel trim. Carefully pry the assembly from the instrument panel. Disengage the locking tabs for the electrical connectors and then disconnect the connectors from the switch assembly.

3

Connect the electrical connectors to the replacement switch, then press-fit the assembly to the instrument panel. Make sure the new switch is in the off position. Reconnect the negative battery cable to the battery, then tighten the clamp. Use a flat-head screwdriver to spread the battery cable clamp, if necessary. Never attempt to pound or hammer a tight battery clamp onto a battery post.

4

Disconnect the memory saver device from the vehicle. Test the headlamp switch to complete the replacement process.
