You can't find the relay because there is not one.

The switches control the lock actuators directly.

i've put a different switch on and it still sends the 12 volts to both sides of the plug when i hit the unlock button but when i hit the lock it only sends 12 volts to one side of the plug

The ground actually comes via the lock switch on the passenger side. Try checking the connection there or that switch may be bad.

Well, it get's more complicated than that. The door locks are hooked into the Retained Accessory Power Module, part #12135089 for 1994 - 1995. This is an electronic module which among other things keeps your window power active for a little while after you turn off the ignition key. The relays look to be part of the module and it's kind of expensive, around $80. It sits somewhere behind the dash, above the radio. I was never able to find mine and I didn't feel like pulling the dash. The problem with my door locks luckily turned out to be just a partially blown fuse.

The RAP module does feed power to the locks, other than that, it has no play in the power lock system and there are no relays that feed back into the module.

The description of the problem seems to have nothing to do with that. He has power, so I did not bring up anything regarding the RAP module.
