both front blinkers out on 2001 Volkswagen Jetta

i'm not sure if both of the front blinker bulbs need to be replaced because they both went out at the same time. i wanted to know if theres a way of seeing if they're still good before i replace them.. and if i need to replace them im not sure how to get to them. thanks
