Re: Trim tabs make sound but do nothing.
 

The pump works, fine but I'm trying to figure out if the hydraulic is bad or if it's just a bad connection.

If the pump is working fine, then you should see movement on at least one of your tabs. If the fluid isn't leaking out, it has to be going somewhere when you build up pressure. Air compresses, fluid doesn't. I'm betting you have to bleed the air out of the system.

Counter Intuitively the system requires more power to bring the Tabs up than it does to put them down. I would suggest you check and clean all the electrical connections. Pay particular attention to both ends of the ground wire.

I do see movement in one of my tabs.

Full movement, or just a little bit?

Full movement. Only works going down though. The wiring is fine. I just checked it.

I think that I need to replace both hydraulics. Anyone else agree?

I don't agree, but I'm not there troubleshooting the issue. By "hydraulics" I assume you are talking about the actuators? Or are you referring to the entire system? Why would the actuators cause the switch to not work in one direction? There is no electrical power to the actuators.

Yes I mean the actuators.

Also if I touch the wires together manually it does nothing.
