I have a 1991 firebird formula and i wanted to know since my passengers power door lock switch unlocks and locks both doors fine, but my drivers lock switch when it works unlocks and locks both doors fine. So what i am trying to say is there a way to fix the switch with out buying a new one?, and / or how do i take the switch out to replace it i dont wont to break anything ?

 

?

 

Sounds like a relay or switch problem. Neither of them would be too expensive... just get new ones. =)
