Is changing the LCM on a Crown Vic a DIY job? on 2005 Ford Crown Victoria

If not, howk much should it cost to get it done. My headlights arent working, but the emergency flashers work if the switch is held. I was told it was the light control module. Does that sound about right? Thanks for any answers. I'm a complete car repair novice.

Not rocket science but need a good bit of car savvy! Video on youtube!!
Sure! Module is prime suspect, btw!!
