Bennet tabs?
 

My bennet trim tabs are stuck in place. I can hear the pump working down in the bilge when working the swithces, but the tab cylynders don't move. I can also extend the ram by hand, so I know they are not completely siezed.
Any one else run into this?

Try opening the fluid bottle to relieve the air.. Worked for me.

if there bennets, they will warrenty pretty much anything :drink:

Make sure there is enough fluid in the bottle.
Also, I have seen the solenoids stick or quit all together. The pump will still run but the fluid won't move. Sometimes tapping on them will shock them loose. (plastic end of a screwdriver etc...)

And yes, Bennett is very helpful in getting you repaired or replaced...
