Please can someone help
The headlights on my UNO Fire don't go on first time.
I have cleaned the connections to earth near the battery, and that worked for a while.
Lately I have found that by tapping the top of the fuse box the lights work.
I have just replaced what the local dealer called a flicker switch - part, 719075 but obviously that was for the indicators - (I kind of knew it)

Is there a similar part for the headlights.
The local Fiat workshop look lost when I try to have this conversation with them and the auto-electricians just don't listen.

How easy is it to remove the whole fuse box?
That would make it easier.

Thanks for any input

It could be a faulty relay, but with an older car, corroded terminals in the fuse box are likely
