What Does The Multifunction Switch Control?

What does a combination switch control?

The electrical switch assembly that controls many vehicle functions is known as the combo switch. It is often used to operate turn signals, high and low beam headlights, and wipers. It is normally positioned on the left side of the steering column, where the driver can quickly reach it.

This switch controls a number of functions such as the hazards, turn signals, blinker, wipers, windshield washer, high beam head lights, and cruise control. The multi-function switch attaches to the steering column and comes with the wire harness needed to connect to your vehicle’s module.

The function of The Multifunction Switch Control?

The multifunction switch is responsible for the operation of the turn signals, headlights, windshield wipers, and washer. It is usually located on the steering column or dash near the driver’s seat. The switch may also be located on the left side of the steering wheel.

Turn signals: The turn signal switch is used to activate the turn signals. The switch is usually located on the left side of the steering wheel.

Headlights: The headlight switch is used to turn the headlights on and off. The switch is usually located on the left side of the steering wheel.

Windshield wipers: The windshield wiper switch is used to activate the windshield wipers. The switch is usually located on the left side of the steering wheel.

How do I know if my multifunction switch is bad?

Issues with the turn signals

A difficulty operating the turn signal is one of the earliest indicators of a problem with the combo switch assembly. Because the turn signals are the most frequently utilized component of the combo switch, they will wear out the quickest. If the mechanism or electrical connections that trigger the turn signal lights wear out, the turn signals may malfunction. Because of worn contacts, the turn signal lever may only work occasionally or not at all.

Issues with the headlights

Problems controlling the headlights are another sign of a possible issue with the combo switch. If the headlight switch incorporated within the combo switch wears out or breaks, it will create difficulties with the headlights. A faulty switch may cause the headlights to only function on specific settings or to not work at all.

Problems with the wipers

Another issue that is often related with a malfunctioning combo switch is problems with the wipers. The wipers will not work correctly if the lever or knob that activates them breaks or gets worn. Depending on the nature of the issue, the wipers may operate sporadically, just on particular settings, or not at all.

The combination switch regulates various functions critical to the safe operation of the vehicle. As a result, if your car exhibits any of the symptoms listed above, get it examined by a competent mechanic, such as one from YourMechanic. They will be able to tell you whether your vehicle requires a combination switch assembly replacement.

How to Troubleshoot Intermittent Wiper and Turn Signal Issues on a Multifunction Switch

Tools Required

• Phillips Screwdriver
• Flathead Screwdriver
• Test light or multimeter
• Digital multimeter
• Shop manual
• Torx-head screwdriver

Process of Troubleshooting Intermittent Wiper and Turn Signal Issues on a Multifunction Switch

Remove the Cover

Before working on the steering column, always disconnect the negative battery connection and wait 15 minutes for the airbag system to shut down. The screws are then removed, and the plastic coverings are lifted off.

Take note of the length, thread style, and placement of each screw as you remove them from the bottom part of the steering column cover. They must return to the same location. Separate the two pieces of the steering column cover by releasing the plastic snap fasteners.

Everything You Need to Know About the Multifunction Switch

Headlights, flashers, wipers, and intermittent windshield washers are all controlled by multifunction switch levers. Hex-head or Torx screws are often used to secure the MFS. Remove them, then remove the switch and unplug the electrical connection. If the issue is a faulty canceling mechanism, the complete MFS must be replaced (auto parts store or dealer).

• If the issue is defective intermittent wiper functioning, follow these steps: If the issue is defective intermittent wiper functioning, use a multimeter to measure the resistance (ohms) values for each position on the intermittent wiper dial. After then, compare them to the handbook.

• If the resistance readings are incorrect: The shop manual will instruct you to replace the MFS if the resistance readings are incorrect. However, you may be able to save a significant amount of money by dismantling the MFS and cleaning the variable resistor contacts yourself. Look for “multifunction switch repair” on the internet.
• If neither method works: If you are unable to dismantle the MFS or the cleaning fails, replace the complete device and reapply the covers.

Press the Switch

Pull out the switch after removing the switch holding screws. Remove the electrical connection.

Examine the Resistance

Check the resistance values using a multimeter connected to the switch’s wiper contacts. If feasible, clean the variable resistor or replace the complete multifunction switch.

How do you test a Multi Function switch?

To test a multi function switch, you will need a jumper wire, a Phillips screwdriver, a flathead screwdriver, a test light or multimeter, and a digital multimeter.

First, remove the cover from the steering column. Next, take note of the length, thread style, and placement of each screw as you remove them from the bottom part of the steering column cover. Separate the two pieces of the steering column cover by releasing the plastic snap fasteners. Once you have access to the switch, use a jumper wire to connect the terminals on the switch.

If the switch is working properly, the test light should illuminate.

If not, use a multimeter to check the resistance values on the switch. Compare these values to the ones listed in the vehicle’s manual. If the readings are not within the specified range, you will need to replace the switch. Finally, reassemble the steering column and test the new switch.

How much does it cost to replace a multifunction switch?

The average cost of replacing a turn signal switch is between $230 and $260, depending on the make and model. Labor fees are forecasted to range from $71 to $90, while parts will set you back between $159 and $170.

Where is the multifunction switch located?

The multifunction switch is located on the lower part of the steering column. It is usually secured by two screws.

Where is the blinker relay switch located?

The turn flasher is most often situated below the driver’s side of the dash and is electrically interconnected with both the turn signal switch and hazard light buttons.

What makes the clicking sound on a turn signal?

When you switch the signal on, a current is sent through the bimetallic spring, which heats it up. The two metals in the spring heat up at different rates, bending in a particular manner as a result. There are no moving parts, so there’s no bimetallic spring to make that clicking noise, yet they still make that sound.

What does the turn signal switch also control?

The turn signal switch may also be responsible for managing the dials and switches, or some of the other car systems. Depending on your car model’s design, you may have access to cruise control features, headlights, fog lights, or windshield wipers from the turn signal switch. Therefore, the turn signal combination switch is somewhat namesake.

What are the 4 types of switches?

Switches can be classified into four categories: momentary switches, double-pole switches, single-pole on/off switches, and double-pole on/off switches.
