4. LOW ARM FORCE
CORRECTION
1. ADD WASHER FLUID TO RESERVOIR.

WIPER SWITCH

DIAGNOSIS AND TESTING - WIPER SWITCH

To test the multi-function/wiper switch, first dis-
connect the switch wires from the body wiring in the
steering column (Fig. 20). Using an ohmmeter, test
for continuity between the terminals of the switch, as
indicated in the following continuity table. The iden-
tity of each terminal is shown in (Fig. 21).
For test purposes, the first position is the OFF
position, the next six positions are for the DELAY
wipe. LOW is the next detent position and HIGH is
the full counterclockwise detent position.
In any wiper switch position, if the control stalk
end cap is depressed, the washer circuit will be com-
pleted.
