not sure where this topic goes... probably not here

but anyhow, i just got my 94 firebird and at first one of the lights didnt pop up and only one bright worked, but some how the brights flickered on and both work, then neither low beams worked... so my friend took them apart today and they both came on as he was taking them apart. then i started my car several hours later and they didnt go back on

obviously some wires are loose or something, anyone know what i need to do to fix them?
