Central Locking System

1995 Rodeo
I am having trouble with my Central Locking System. If I lock the driver side door then all the other doors will lock. However, the unlock feture does not work. I can hear a clicking when I unlock the driver side door but the clicking comes from the passenger side. Are the relays in a series and could the passenger side relay be bad. Would this cause all the doors not to work? Any help would be greatly appreciated.

I am having a similar problem with my 93 Rodeo. The problem is intermittent -when I push the driver's side lock up or down, the other locks *sometimes* do not lock or unlock. The problem comes and goes. I also hear a clicking that comes from the passenger's side.

Has anyone else experienced this issue or fixed it?
Thanks!
