Intermittent Wiper Switch Test

WARNING: This page is about a different car, the 1994 Plymouth Sundance and 1994 Dodge Shadow. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: On vehicles equipped with air bag restraint system, use extreme caution when servicing to avoid personal injury and vehicle damage. See AIR BAG RESTRAINT SYSTEM article in the ACCESSORIES/SAFETY EQUIPMENT Section before servicing steering wheel or column.

Disconnect the intermittent wiper switch connector. Using an ohmmeter, test for continuity between specified switch terminals. Refer to INTERMITTENT WIPER SWITCH CONTINUITY . See Fig 1 .

For test purposes, going clockwise, perform the following:

First is OFF position.
Counterclockwise rotation is DELAY position.
Next detent is LOW position.
Full counterclockwise is HIGH position.

INTERMITTENT WIPER SWITCH CONTINUITY

Switch Position

Continuity Between Terminals

OFF

6 (BRN/WHT) & 7 (DK GRN)

DELAY ⁽¹⁾

1 (WHT/BLK) & 2 (VIO); 1 (WHT/BLK) & 4 (DK BLU);

2 (VIO) & 4 (DK BLU); 8 (DK GRN/WHT) & 9 (BRN/WHT)

LOW

4 (DK BLU) & 6 (BRN/WHT)

HIGH

4 (DK BLU) & 5 (RED/YEL)

WASH

3 (BRN) & 4 (DK BLU)

⁽¹⁾	Resistance at maximum delay is 210,000-390,000 ohms. Resistance at minimum delay is zero, with ohmmeter set on high ohm scale.
