Trim tabs not working

Hello friends and fellow boat owners.
I can’t get neither one of my trim tabs to work. I don’t know what happened that would make both of them stop working at the same time. Can anyone help me with this.

Assuming you have the Lenco tabs, there is a controller box behind the dash panel. Open it up and look for corrosion.
