ok so i have a 1991 volvo 240 and just have some minor problems i dont know how to fix 1) when you put the key in the driverside door it only unlocks the driverside door but if you wiggle the key in the lock it slowly starts to unlock the other 3 doors but never unlocks them enough to open. Now if another door is unlocked and i push the driverside door lock down before i get out of the car it locks the other doors perfectly fine. Im just having a problem unlocking all the doors when the key is in the lock because they just wont. I dont know what to do. My dad has the same model and year as me and his works fine. when he puts his key in the driverside door and turns it to unlock the door it unlocks all the doors and trunk but mine wont. Does anyone know what could be wrong?
