Condensation in drivers headlight Insignia 2015

[Yvonne]

Having problems with condensation in drivers headlamp, which is causing main beam to keep flashing off and on. Separate issue with dampness in drivers footwell which commenced during heaving flooding end of October / nevemner. Also noticed condensation inside rear window today. What else!!! Cars 2015 with 78 k genuine miles. I’m worried leak maybe coming from back window or front window. Mine field as where to start. Service complete with timing belt and water pump needing done. Expensive time ahead.
