Door Locks

[nysvx10]

HI, I have a 1992 SVX, and I just bought a keyless remote battery. The remote works fine now. It arms/disarms the alarm and locks/unlocks the passenger side door. The problem is that it doesn't lock or unlock the drivers side door. I took the door panel off and couldn't see andything that might be a cuase. I hear the motor working, but the lock doesnt move. I can only lock the drivers side door with the key or from the inside. Another thing is that both door locks do not seem to be connected anymore...like when I got the car I could unlock the drivers door and the passenger side would unlock also, but now they are independent of each other. Thanks for any help
