Wiper Relay: Description and Operation
SYSTEM 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 on the conventional ISO relay.
The intermittent wipe relay is a electromechanical device that switches current to the windshield wiper motor or wiper motor park switch when the
relay is energized or de-energized by the Body Control Module (BCM) in response to the proper inputs from the windshield wiper
(multi-function) switch. See the Diagnosis and Testing for more information on the intermittent wiper relay.
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.
