Component Testing
WARNING: This page is about a different car, the 2008 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
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.NOTE: 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.
- If greater than 5 ohm, replace the turn signal/multifunction switch.
Wiper Switch Values
WIPER SWITCH VALUES SPECIFICATIONS
| Switch Position | Resistance |
|---|---|
| Off | Infinite |
| Mist | 300-364 Ω |
| Delay 1 | 3.48K-4.25K Ω |
| Delay 2 | 2.52K-3.08K Ω |
| Delay 3 | 1.78K-2.18K Ω |

Windshield Wiper Motor Dynamic Test
- Ignition OFF, disconnect the harness connector at the windshield wiper motor.
- Install a 25-amp fused jumper wire between the control terminal E and 12 volts. Install a jumper wire between the ground terminal C and ground.
- The wiper motor should be in low speed mode.
- If the wiper motor is not in the low speed mode replace the motor.
- Install a 25-amp fused jumper wire between the control terminal D and 12 volts. Install a jumper wire between the ground terminal C and ground.
- The wiper motor should be in the high speed mode.
- If the wiper motor is not in the high speed mode replace the motor.
