Nissan 50HP DFI (2003) trim goes up but will not go down. You can here both the switches click but no downward movement. Any suggestions?

May be a bad relay. Just because it clicks does not mean its good. Try swapping them.
Thanks Barnacle Bill, I’ll try it.
yes what Bill said . did that on my pontoon CMC T&T.
Had that happen to my 90hp Merc .... bad relays .... bought 2 new ones & swapped them out, myself. Good thing it was a pretty simple, straightforward job, as I'm not the least bit mechanically inclined. :fingerdance
Where are the relays located?
Mine were located on the side of the engine block.Quote:

Pushed up on trim switch and hollered for wife to hold the up while I disconnected the battery.

Swap the relays and you can diagnose whether it's the switch or the relays. Where I shop switches and relays are expensive and non returnable. And if it is the switch disconnect it till you replace it. Lesson learned for me
