Outer cover
Check the state of rain sensor outer cover. Check whether fixing portion of the cover has loosened and moving so that
damaging sensor.
And also check whether there are interferences with windshield and head lining.
Spring clip
To check whether the rain sensor has separated from coupler, remove the outer cover and check spring clip state.
Connector
Check close connection between connector terminal and wiring and then locking when terminal is inserted into connec-
tor correctly.
And check connection between wiring connector and rain sensor connector not to cause poor connection.
Relay
Check wiper low speed relay and wiper high speed relay for normal operation. When the relay is blown, wiper motor
cannot be operated so the wiper blade does not respond in AUTO mode.
Circuit
Check circuit. Especially check whether variable resistance of multi-function switch inputs normally. To check it, wiper
motor should operate once every time when the variable resistance knob on the multi-function switch has rotated from
slow to fast by stage (It is called instant wipe). Also check whether correct position signal of the wiper motor inputs
correctly. If there is no correct position signal, wiper motor can be operated more fast than normal and wiper motor
intermittent speed changing point can be incorrect so the wiper motor does not operate normally.
Cautions when removing rain sensor unit
1. Remove outer cover. If remove forcefully, coupler fixing hook can be damaged. When removing, pry off
fixing hook outer with small "–" driver through hole on the cover.
2. To remove rain sensor from coupler, open spring clip with small "–" driver.
3. Disconnect wiring connector from sensor.

Rear Wiper Control System

General
Conventional rear wiper system is controlled when rear wiper
relay is operated by operating switch. However, rear wiper
system on Rexton is controlled by separate ECU. The reason
is that the conventional vehicle has rear wiper brush on the
rear glass but the Rexton can open the rear glass so cannot
install rear wiper brush on the rear glass. The rear wiper brush
is installed on the back panel and the wiper motor is operated
in 2 stages.
