Removal & Installation

1. Disconnect and isolate the battery negative cable. WARNING(bags can kill, my comment)
   Wait two minutes for the airbag system reserve capacitor to discharge before performing further diagnosis or service.
2. From below the steering column, remove the three screws that secure the lower steering column shroud to the multi-function switch mounting housing.
3. Using hand pressure, push gently inward on both sides of the upper shroud near the parting line between the upper and lower shrouds to release the snap features that secure the two shroud halves together.
4. Remove both the upper and lower shrouds from the steering column.
5. Remove the Steering Control Module (SCM) from the steering column.
6. Remove the two screws that secure the left multifunction switch to the SCM .
7. Disengage the two retaining tabs , next to the screw mounts that secure the left multi-function switch to the SCM.
8. Disconnect the left multi-function switch from the SCM.

To install:

1. Position the left multi-function switch onto position on the Steering Control Module (SCM) .
2. Engage the two retaining tabs, next to the screw mounts that secure the left multi-function switch and firmly snap into place.
3. Install the two screws that secure the left multifunction switch to the SCM. Tighten the screws to 22 inch lbs. (2.5 Nm).
4. Position the lower steering column shroud to the underside of the steering column.
5. Install the three screws that secure the lower steering column shroud to the multi-function switch mounting housing. Tighten the screws to 17 inch lbs. (2 Nm).
6. Position the upper column shroud over the steering column with the hazard warning switch button inserted through the hole in the upper shroud.
7. Align the snap features on the upper and lower shrouds and apply hand pressure to snap them together.
8. Reconnect the battery negative cable.

That sounds like the multifunction switch is the fault. The flasher on this vehicle is part of the hazzard switch. It recieves power for turn flashing from the turn signal switch. It is very common for the turnsignal (multifunction) switch to become worn and supply partial power to the flasher (hazzard switch) when not on which results in this fast clicking without any lights on. To be certian without taking out any tools whatsoever the next time the clicking happens jiggle the turn signal switch and see if it goes away or changes at all. If it does you need the turn signal switch. I'm going to include replacement instructions for that below because I am confident that is what you will need. Please ask if you have any further questions.



Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
Disconnect the negative battery cable.
Disable the supplemental inflatable restraints (SIR).

Installation

1. NOTE: When the battery (10655) is disconnected and reconnected, some abnormal drive symptoms may occur while the vehicle relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 mi) or more to relearn the strategy.
   To install, reverse the removal procedure.

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.

To install:

1. Connect the combination switch electrical harness connectors ensuring that the connectors are fully engaged. The wiring for the switch is to be routed under the shift position indicator cable.
2. Install the combination switch with 2 self-tapping screws. Tighten to 19-25 inch lbs. (2-3 Nm).
3. Install the upper and lower steering column shrouds. Install the retaining screws and tighten to 9 inch lbs. (1 Nm).

5. Install the ignition key and tumbler assembly.
6. Connect the negative battery cable.
7. Check the steering column and combination switch for proper operation.

Lights intermittent can be caused by switch or relay. Try swapping the Low Beam relay with another similar relay (horn relay is a good choice) to see if that resolves it. These relays are in the Junction Block--may be under the hood or in the car but not in the big box by the battery). If this doesn't fix it, the problem is likely the headlamp switch.

Horn coming on is usually caused by a broken switch or stripped wire insulation inside the steering column. You would usually have to take the steering wheel off to fix it, and this requires special tools; however, if the problem happens to be under the steering column shroud, you may be able to fix it without taking off the steering wheel. Take the shroud off and see if you can follow the black/red horn wire. Follow it as far as you can to check for stripped insulation contact with any metal. If you lights switch is bad, you can also change that while you have the shroud off.

Please let me know if you have questions.

REMOVAL
WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.

1. Disconnect and isolate the battery negative cable.
2. Remove the screw (2) that secures the tilt steering column knob (1) and remove it from the tilt actuator (3) on the left side of the column.
3. From below the steering column, remove the two outboard screws that secure the upper column shroud (1) to the lower shroud (3).
4. Using hand pressure, press inward on both sides of the upper shroud above the parting line of the lower shroud to release the snap features that secure the two shroud halves to each other.
5. Remove the upper shroud from the lower shroud and the steering column.
6. Remove the one center screw that secures the lower shroud to the steering column (4).
7. Remove the lower shroud from the steering column.
8. Disconnect the wire harness connector (2) from the back of the multi-function switch housing (1).
9. Rotate the steering wheel far enough to access and remove the two screws (4) that secure the switch to the multi-function switch mounting housing (3).
10. Grasp the switch control stalk and pull it toward the left side of the vehicle to remove the switch from the mounting housing.

INSTALLATION
1. Slide the multi-function switch (1) into the multi-function switch mounting housing (3) from the left side. Be certain that the alignment pins on the top and bottom of the switch are properly engaged in the channels of the mounting housing.
2. Rotate the steering wheel far enough to install and tighten the two screws (4) that secure the switch to the mounting housing. Tighten the screws to 2 N·m (20 in. lbs.).
