No there is no relay. I have a wiring diagram for the 87-88 maybe 89. I am not sure if they changed for the later ones. It should be pretty much the same. I would check the grounds first. You can see in this diagram how both sides come back through the same ground point. If you have a ****ty ground it could cause it to be slow.

Yes to test the actuator itself you would just jump 12v to one side and ground the other side. Reverse the wires and the actuator should go the other direction. No I am not exactly sure where the ground is. I am assuming somewhere in thedriver door. But you could follow the black wires off of the left switch and see where they go.
Edit: I woulndt replace those switches. I would test them first. But it sounds like they are working. You see how power comes in the middle of the switch and then goes out the the other switch through the motors then back through both switches before grounding. If they didnt work the actuators would not even move.

Also that 30A Circuit breaker, that would be in the fuse box under the hood right?

Yes the CB should be under the hood. Those switches should still be good. I assume they are working. You can test them real easy. Do you own an ohm meter? Or maybe a test light? If you do disconnect the switches. Put one lead in one side of the switch and the other on the middle terminal. Press the switch and you should get continuity. Take the lead and put it on the other side press the switch and then you should get continuity. It sounds to me like you switches are working. If one of them was not working then your motors wouldnt have even done anything. Can you see how power has to go back and forth through the switches and motors then back through the switches before it grounds?

I dont think that where they are in the circuit should matter much unless the terminals are corroded. Yes if one side of the switch goes out everything quits working. When you press up you are making power go through the up part of the switch, But you are also sending the ground through the down part of the switch. And it reverses if you press down. Power goes through the down side of the switch and the ground goes through the up part. I hope I am making some sense with this. I am having trouble trying to explain it.
Edit: Have you tried them not connected to the locks? Just the actuators plugged into the harness?
