I have the all in one Quicksilver Remote Controler. The trim, tilt, clutch are all on one controller. Hopefully the picture of it is attached to this post. Anyway...when I partially depress the trim/tilt thumb switch the trim is supposed to engage but it doesn't. When I FULLY depress the switch, the tilt works as it's supposed to. What should I look for? Loose wire etc or replace parts or replace entire controller.
