Diagnosis And Testing - Wiper Switch
WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, 2004 Chrysler Concorde, and 2004 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
To test the multi-function/wiper switch, first disconnect the switch wires from the body wiring in the steering column (Fig 1 ). Using an ohmmeter, test for continuity between the terminals of the switch, as indicated in the following continuity table. The identity of each terminal is shown in (Fig 2 ).
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 completed.
