Default Drive goes down not up

Bravo xz drive power trim only works going down. I replaced 1 solenoid. Goes up if I reverse the big blue and big green wires on the solenoids . Power to the solenoids from the switches from the little blue and green wires. Very frustrating. Any help would be appreciated

Probably need more info, but I'm thinking a bad switch Throttle or limit) or corrosion on the 3 prong connector
Does the trailer switch bring it up?

So you get power to the solenoids through the small green/blue wires.....does each solenoid click as you get that power signal? If not then check the ground on the solenoid on the one that's not clicking....if ground is good then replace solenoid.
If solenoid does click then check the output of the big blue wire (that's the one "usually" wired for UP position) or green if wired opposite....if there's no power output, then the contact inside the solenoid is bad and you need to replace the solenoid and you should be good to go.
If you do get a power output on the big colored wire then i would check the connector for corrosion...or there's a break in the wire going to the motor.
You can also bypass all the solenoids and test the pump itself by unhooking the green and blue motor wires from the solenoids and going straight to battery....you can keep the black ground wire hooked up assuming its got a good ground since the motor does work in one direction....then run a length of wire from the the battery positive and hit the green or the blue wire on the pump motor one at a time and it will trigger it to work. If it still doesn't go up then the wire connection going to the motor itself has a break somewhere...and you'll probably need a new motor or a new pump assembly depending on how you want to fix it.

Check your connection at the 3 prong connector leading into the pump assembly. I just fixed a friend's drive last week that would not go down. I cannot edit the above picture, but the connection I am referring to is to the right of the Item marked "F". His had some corrosion and was not plugged all the way in. There was also some corrosion in the fuse holders around item "A". Be patient.

Suspect any "push on" electrical wire connectors, especially any on a solenoid. Replace with "bolt and nut" type connectors to solenoids.

As mentioned above,,,,Does it go up if you hit the " trailer " button? If yes, its the trim limit circuit, if not I would look at the solenoid. Also, do you hear a " click " from the pump assy when you hit the trim up switch? That would also point to a bad solenoid.
