Multifunction Switch
- Ignition OFF, disconnect the X3 harness connector at the turn signal/multifunction switch.
- Test the resistance between terminals D and E. Rotate the wiper switch and compare the resistance readings to the values in the Windshield Wiper Switch Values table below for MIST, each DELAY and LOW speed.
- If the resistance is not within the specified range, replace the turn signal/multifunction switch.
- Test for infinite resistance between terminals D and C while rotating the wiper switch to MIST, each DELAY and LOW speed positions.
- If the less than infinite, replace the turn signal/multifunction switch.
- Test for less than 5 ohms of resistance with the wiper switch in the High speed position.
- If greater than 5 ohm, replace the turn signal/multifunction switch.
- Test for infinite resistance between terminals D and B while rotating the wiper switch to MIST, each DELAY and LOW speed positions.
- If less than infinite, replace the turn signal/multifunction switch.
- Test for less than 5 ohm of resistance while pressing the WASHER switch.
- If greater than 5 ohm, replace the turn signal/multifunction switch.
IMPORTANT:
If the switch tests open in any switch position other than Off, test the wiper/washer switch signal circuits for a short to voltage before replacing the switch.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- β’ You smell fuel, burning insulation, or see smoke.
- β’ Brakes feel soft, pull hard to one side, or make grinding noises.
- β’ The engine overheats, stalls repeatedly, or misfires under load.
- β’ You are missing required tools, torque specs, or safe lifting equipment.
- β’ You are not confident in the next step or safety outcome.
