Do I need to have my wiring checked?

So I had to replace my passenger turn signal in my
Chevrolet uplander and the next day it was blown
again. Around the time the first bulb went out my
cigarette lighter ports stopped working. We
checked the fuses and found one blown so I
replaced the bulb again. But the bulb looked
burned. Should i get it checked for a wiring
problem?  We just bought the car used.
