Isuzu Rodeo rear wiper malfunction due to relay issues causing intermittent function and complete failure on Isuzu Rodeo

Some Isuzu Rodeo owners report experiencing rear wiper malfunctions due to relay issues, which can lead to intermittent function or complete failure of the wiper system. These problems often stem from the alarm and relay control unit, which manages the rear wiper/washer system. Symptoms such as inconsistent operation may indicate that relay issues are affecting the wiper motor's control. Additionally, manufacturers include indicators that signal impending circuit failures, like the parked position of the wiper blade. Owners suspecting relay problems are advised to check the rear wiper/washer switch for continuity and ensure the Body Control Module (BCM) receives the correct signal voltage across all switch positions. Understanding these relay-related issues is crucial for effectively diagnosing and resolving rear wiper problems in the Isuzu Rodeo.
