It sounds like moisture may have affected the electrical connections in your Renault Espace, particularly if the dashboard and radio controls are unresponsive. Check for any visible water damage or loose connectors, especially around the fuse box and dashboard area. You may also want to dry out the interior and electrical components thoroughly. If the problem persists, a professional diagnostic may be necessary to identify any damaged components or wiring.
