Wiper Switch (Intermittent Wipe)

Disconnect wiring from switch and remove switch from instrument panel. Use a continuity tester or ohmmeter to check for continuity between contact terminals of switch as shown in table. For test purposes, first position is "OFF", next is slide for "DELAY WIPE", "LOW" is first detent and "HIGH" is second detent. Ground is the case of wiper switch.

Resistance at maximum delay position should be between 270, 000 ohms and 330, 000 ohms.

Resistance at minimum delay position should be zero with ohmmeter set on the high ohm scale and positive of ohmmeter connected to "P₂ " and negative connected to "G" should show low resistance.

Negative of ohmmeter connected to "P₂ " and positive connected to "G" should show an open circuit or very high resistance. If same reading in both tests, switch is defective.
