Dodge Caravan intermittent accessory failure potentially related to faulty BCM or grounding issues on Dodge Caravan

Some Dodge Caravan owners report experiencing intermittent accessory failures, which may be linked to a faulty Body Control Module (BCM) or grounding issues. Problems with the BCM can lead to various electrical malfunctions, affecting accessory functionality due to its role in communication with other control modules. Additionally, some owners find that faulty grounding can contribute to these accessory failures, emphasizing the importance of secure and corrosion-free ground connections. Troubleshooting steps such as the "battery lobotomy trick"—disconnecting a battery cable and briefly touching it to the other—are suggested to help drain residual charges causing issues. Owners are also advised to inspect wiring for damage, particularly around the BCM and under the passenger seat, where electrical problems have been noted. If these issues persist despite basic troubleshooting, seeking assistance from a qualified mechanic or dealership specializing in Dodge Caravan electrical systems is recommended for effective resolution.
