Definitely the fuse, all those items would probably run off of an intermittent relay running off of the same fuse... .
Probably not a fuse- from the repair manual:
MODULE-STEERING CONTROL DESCRIPTION
This vehicle is equipped with a Steering Column Control Module (SCCM) The SCCM is secured near the top of the steering column below the steering wheel and is completely concealed beneath the steering column shrouds. It is
installed as a modular unit that supports the left (lighting) multi-function switch (1) and right (wiper) multi-function switch (6). The controls for each of these switches extend through appropriate clearance holes provided in the
steering column shrouds. The microprocessor-based Steering Control Module (SCM) (2) utilizes integrated circuitry and information carried on the Controller Area Network (CAN) data bus along with several hard wired analog and multiplexed inputs to monitor both the right and left multi-function switches. The SCCM uses a Local Interconnect Network (LIN) data bus for
exterior lighting and wiper functions. The LIN data is sent to the Cab Compartment Node (CCN) and the CCN then sends it out on the CAN data bus (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/COMMUNICATION - DESCRIPTION - CAN BUS). The SCCM is available for service replacement as a unit or each individual component:
1 Clockspring (with integral Steering Angle Sensor if equipped)
2 Left Multi-Function Switch
3 Right Multi-Function Switch
The Steering Control Module (SCM) communicates over the Local Interconnect Network (LIN) data bus with other electronic modules in the vehicle and/or a diagnostic scan tool. The horn switch circuits pass through the clockspring to the Cab Compartment Node (CCN) and the CCN sends a CAN message to the Totally Integrated Power Module (TIPM) to control the horn. The CCN stores Diagnostic Trouble Codes (DTC’s) for the SCM. The right (wiper) multi-function switch has several inputs to the CCN.
The SCM is connected to a fused B(+) circuit and receives a path to ground at all times. These connections allow it to remain functional regardless of the ignition switch position. The driver airbag squib circuits of the clockspring,
the horn, and the speed control switch circuits pass through the SCM, but the SCM does not monitor, and has no control outputs related to these circuits. Any other input to the SCM that would cause a vehicle system to function but does not require that the ignition switch be in the On position, such as turning on the lights or sounding the horn, prompts the SCM to wake up and transmit on the CAN data bus.
The most reliable, efficient, and accurate means to diagnose the SCM, the CAN data bus, the hard wired inputs or the electronic communication related to SCM operation requires the use of a diagnostic scan tool. Refer to the
appropriate diagnostic information. The integral SCM is not available for separate service replacement. If found inoperative or defective, the entire left (lighting) multi-function switch must be replaced (Refer to 8 - ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/LEFT MULTI-FUNCTION SWITCH - REMOVAL).
