- 3Check that the connectors at the switches are firm and not corroded
- 4Inspect the wire from the switches for chafing and pinch damage
- 5With the switches disconnected and the ignition on, use a multimeter to check whether the wire from the switches has voltage to the body
- 6If the fault returns, have a workshop with diagnostic equipment check the switches and the wire
