Croma (194) Luggage compartment lighting

Hello, I’ve been a proud owner of a Fiat Croma 1.9 Multijet (110kW) built in 2008. I bought the car as an annual car from the dealer and it’s all tiptopp. But I didn’t notice a mistake: the boot lighting doesn’t work! The Croma has lights on both sides in the trunk. The car probably stood in the showroom, so it can be that they have been switched off somehow, so that the battery is protected if the flap remains ? D he light bulbs I have checked, are usually contacts etc. as well. Cable cords in the safety box back and front I have also checked once, everything seems to be firm. Does anyone know how to get these things back on ? Greetings, Chris
