6 BE18 BODY ELECTRICAL SYSTEM COMBINATION SWITCH DISASSEMBLY 1. REMOVE WIRE HARNESS HOLDER NO.1 2. REMOVE WIRE HARNESS HOLDER NO.2 3. REMOVE TERMINALS FROM CONNECTOR (a) Release four tabs and open the terminal cover. (b) From the open end, insert a miniature screwdriver between the locking lug and terminal. (c) Pry down the locking lug with the screwdriver and pull the terminal out from the rear. w/o SRS 2. REMOVE LIGHT CONTROL SWITCH AND LIGHT DIM MER TURN SWITCH UNIT (a) Remove the set plate. (b) Remove two screws and light dimmer turn switch unit. (c) Slide out the light control switch from the switch body with the spring. (d) Remove the roller.

7 BODY ELECTRICAL SYSTEM BE19 3. REMOVE WIPER AND WASHERS SWITCH Remove four screws and the switch form the switch body. w/ SRS 4. REMOVE LIGHT CONTROL SWITCH AND LIGHT DIMMER TURN SWITCH UNIT (a) Remove four screws and the spiral cable from the switch body. (b) Remove two screws and the Lock plate from the switch body. (c) Remove two screws and the ball set plate from the switch body. (d) Remove the ball and side out the switch from the switch body with the spring. (e) Remove two screws and light dimmer turn switch unit. 5. REMOVE WIPER AND WASHERS SWITCH Remove six screws and the switch from the switch body.

8 BE20 BODY ELECTRICAL SYSTEM COMBINATION SWITCH ASSEMBLY w/o SRS INSTALL PARTS OF COMBINATION SWITCH IN REVERSE SEQUENCE OF REMOVAL HINT: When installing the light dimmer turn switch unit in the switch body, match up each switch position of the light control switch lever with the corresponding switch position of the light dimmer turn switch unit. After installing the light control switch to the switch body, insure that the switch operates smoothly. COMBINATION SWITCH ASSEMBLY w/ SRS INSTALL PARTS OF COMBINATION SWITCH IN REVERSE SEQUENCE OF REMOVAL HINT: When installing the light dimmer turn switch unit in the switch body, match up switch position of the light control switch level with the corresponding switch position of the light dimmer turn switch unit. After installing the light control switch to the switch body, insure that the switch operates smoothly. NOTICE ADJUSTMENT OF SPIRAL CABLE (a) Check that the front wheels are facing straight ahead. (b) Turn the spiral cable counterclockwise by hand until it becomes harder to turn the cable. (c) Then rotate the spiral cable clockwise about 3 turns to align the red mark. HINT: The spiral cable will rotate about 3 turns to either left or right of the center. The connector should be straight up. (d) Install the steering wheel so that the match marks will not be misaligned.
