Ford Taurus cooling fans require battery connection to operate on Ford Taurus

Some Ford Taurus owners report experiencing issues with their cooling fans due to improper battery connections. These issues can arise if the fan's direct connection to the battery through terminal 30 is not established correctly, potentially leading to malfunction. Additionally, if the low-speed power wire connected to terminal 87 is not functioning properly, it may hinder fan operation. Some owners also find that if terminal 86 is not grounded correctly, the fans may not operate as intended. Furthermore, problems can occur if terminal 85, which should connect to a 12V source that activates only when the key is turned on, is not properly wired. These connection issues can affect the cooling fans' performance and overall vehicle operation.
