Hoping someone can give insights on my 2010 Formula 34PC 'coz I'm having a weird issue with my trim tabs! One of them seems to keep trimming down even after I let go of the button, like it's stuck in the down position. Also, the button for the other tab is making a distinct popping sound when I press it, which it definitely didn't use to do. Any ideas on what might be going on here and how to fix this? Thanks for any help!

That distinct popping sound from the switch usually indicates an internal electrical fault or arcing within the switch itself. It's a strong sign the switch is failing. Replace that trim tab switch. It's a relatively easy and inexpensive fix that could prevent further issues down the line
 
Definitely a control issue, possibly a stuck relay or water intrusion in the switch itself, check your switch panel for corrosion or loose wiring, then move on to the control box and relays

Could be your trim button might be sticking. One way to check is to have someone hold down the button while you test the voltage at the pump,, if the voltage stays on even after releasing the button, thats a clear sign the button or its wiring is sticking and keeping the pump powered when it shouldn't be. It's a simple test but can save you a lot of guessing.
