FRONT WIPER AND WASHER
WIPER AND WASHER SYSTEMS
1. Front Wiper and Washer
A: GENERAL
1. FRONT WIPER
1) The front wiper is of a tandem type featuring wide wiping area. The blade is installed to the arm
by means of U-hook joint to improve serviceability.
2) The front wiper operates in the HI and LOW speed modes and the INTERMITTENT mode.
The operation modes can be selected by turning the wiper switch incorporated in the combination
switch.
3) In the INTERMITTENT mode, the intermittent unit installed behind the combination switch con-
trols the front wiper operation interval.
4) The front wiper system uses a modular construction in which the wiper motor forms an integral
part of the linkage. The motor is installed on the body through rubber mounting.

5) The size of the motor is minimized by changing the stator shape, coil windings and the magnet.

prevent the wiper blade being lifted up.
