MULTIFUNCTION Switch

NOTE: For complete testing of the multifunction switch, see STEERING COLUMN SWITCHES - PICKUP article.

Wiper switch is incorporated into multifunction switch on steering column. Disconnect multifunction switch 7-pin harness connector (X-254). Measure resistance between specified switch terminals (component side) with wiper switch in specified position. See Fig 1 . See WIPER SWITCH TEST  table. If resistance is not as specified, replace multifunction switch.

(1) Approximate values.
(2) Resistance should be 5 ohms or less.
(3) Rotating INT (interval) knob from minimum to maximum will change resistance value.
(4) Resistance should be greater than 10 k/ohms.
