Technical Fiat cold, no lights

[Nopower]

Hi just purchased a 1998 Ulysse, however since day 1 the temp is always cold, even with the temp gauge reading high.
I have convinced myself it is the head gasket however my Father in law who I got the car from says it has been like that for a few years and it has never been a problem for him.
And also this evening was driving down the motorway and lost all lights, could it be a fuse, if so where is the fuse located.
sorry to mix two into one.

Many thanks.

your water system might need bleeding if your not getting heat from the blowers when temp is up it could also be a sticky thermostat to normal also the fuses are located behind the glovebox take out the glovebox there is a removerble panel behind there
