Wiper Relay: Description and Operation
The intermittent wipe relay is a International Standards Organization (ISO) micro-relay. The terminal designations and functions are the same as a
conventional ISO relay. However, the micro-relay terminal orientation (or footprint) is different, current capacity is lower, and the relay case dimensions
are smaller than those of the conventional ISO relay.
The intermittent wipe relay is a electromechanical device that switches battery current to the windshield wiper motor or wiper motor park switch when
the relay coil is grounded by the Central Timer Module (CTM) in response to inputs from the windshield wiper (multi-function) switch. See Intermittent
Wipe Relay in the Diagnosis and Testing for more information.
The intermittent wipe relay is located in the Power Distribution Center (PDC), in the engine compartment. Refer to the PDC label for relay identification
and location.
The intermittent wipe relay cannot be repaired and, if faulty or damaged, it must be replaced.
