Dodge Durango excessive voltage causing bulbs to blow, likely due to TIPM module failure on Dodge Durango

Some Dodge Durango owners report experiencing excessive voltage issues that cause bulbs to blow, often linked to a failing Totally Integrated Power Module (TIPM). This problem can lead to erratic electrical behavior, including voltage spikes that may damage bulbs. Symptoms of a malfunctioning TIPM may include intermittent starting problems, non-operation of certain systems, and erratic power window behavior. As the TIPM manages the vehicle's electrical functions, prolonged unstable voltage conditions, potentially caused by a weak battery or poor charging system, can contribute to its failure. Owners suspecting a TIPM issue are advised to diagnose the module by checking power and ground wiring and conducting voltage drop tests before considering resetting, reprogramming, or replacing the TIPM. To address these electrical issues, it is recommended to have the TIPM inspected and potentially replaced.
