Few major problems. Need to know what I'm looking at parts/labor wise. Help!!

What is your question?

I've been having problems with my directional/hazards for the past year now and I was able to resolve the issue in the beginning simply by replacing the fuses; but that only lasted for a week or so until they stopped working again. it then got to the point where the fuses would instantly blow every time I tried putting a new one in. The dashboard lights stopped working in October (warning lights on dash still work though) ALSO: my sons father got into an accident this past june which resulted in significant front end damage to the drivers side quarter panel/turn signal light assembly and it has not been repaired since then. The two prongs in the turn signal light bulb socket were corroded, (I'm assuming from being exposed to the elements for so long.) Honestly don't know how to diagnose what is causing the directionals, hazards and dash lights to malfunction and if i need to take apart the dash to figure it out or something else?
