Ford Aerostar strange squealing noise and dashboard lights flickering when in reverse on Ford Aerostar

Some Ford Aerostar owners report experiencing a strange squealing noise along with dashboard lights flickering when in reverse. This squealing noise may stem from various issues, including worn window seals, worn brake pads, or mechanical problems like a slipped belt or a damaged hose. Additionally, the flickering dashboard lights could indicate electrical issues, such as loose or corroded battery terminals or a faulty connection to the starter. Some owners find that the source of the noise may actually be linked to mechanical components rather than the dashboard itself. To address these concerns, it is recommended that owners check the battery connections, inspect the starter motor for faults, and examine mechanical components for any underlying issues. If these measures do not resolve the problems, seeking assistance from a professional mechanic is advisable to ensure the vehicle's safety and proper functioning.
