All vehicles are equipped with an air bag system. The system must be disabled before performing service on or around system components, steering column, instrument panel components, wiring and sensors. Failure to follow safety and disabling procedures could result in accidental air bag deployment, possible personal injury and unnecessary system repairs.
- Before servicing the vehicle, refer to the Precautions Section.
- Disconnect the negative battery cable.
- Drain the cooling system. Discharge the air conditioning system.
Disarm the air bag system.
NOTEWait at least 60 seconds before performing and work once the system is disarmed.

Remove the steering shaft cover installation bolt.
NOTEThe tilt lever should be in the lock position before the steering column shaft assembly is removed, and should remain in the locked position until it is reinstalled. If the steering column shaft assembly is removed with the tilt lever released, or the tilt lever is released after removal the assembly cannot be reinstalled correctly. If the assembly is installed incorrectly, the collision energy absorbing mechanism may be damaged.
- Ensure that the tilt lever is in the lock position. Remove the steering shaft mounting bolts. Remove the assembly from the vehicle.
Remove the instrument panel assembly from the vehicle.
NOTEDo not subject the SRS-ECU to any shocks when removing or installing the instrument panel.
- Remove the intake duct, right side foot duct, joint duct and center duct.
- Remove the heater hose connection, flexible suction hose connection, liquid pipe connection and O-ring and left side foot duct.
- Remove the heater case from the vehicle.
Disassemble the heater unit as necessary for access to components.
Installation is the reverse of the removal procedure.
NOTEWhen installing the heater/evaporator unit do not allow it to bump against the SRS-ECU or any of its components.
Ensure that the tilt lever is in the lock position. Install the steering column shaft.
NOTEDo not release the tilt lever until the steering column shaft has been installed. Torque the retaining bolts 80-124 inch. lbs.
NOTEWhen installing the clock spring, ensure that the mating marks are properly aligned. If not the steering wheel may not rotate completely during a turn, or the flat cable in the clock spring could be damaged. This would prevent normal SRS operation and possibly cause serious injury to the driver.
- Turn the front wheels to the straight ahead position. Then install the clock spring to the column switch.
To align the mating marks of the clock spring, turn the clock spring counterclockwise fully. Then turn it back approximately 3-3/4 turns counterclockwise to align the mating marks.
NOTEWhen installing the steering wheel, be sure that the harness of the clock spring does not become caught or tangled.
- Check and adjust all fluid levels. Properly recharge the air conditioning system.
