Hi,

I recently bought a 1998 Geo Prizm and found out the back passenger door doesn't lock when all of the other doors do. So, when I put the key in and turn it twice everything unlocks but that door and the same for when I lock my car, everything locks but that. I can lock and unlock it manually though. So basically my question is, what do you think is wrong. I'm pretty sure it's just the actuator, which I could replace, but didn't know if it might actually be the motor... Thanks!
