4x4 troubles

Hello, this is my first post here. I'm having some trouble with my 4x4, last year it stopped working all together I could here what sounded like the diff click into place then the light would start flashing. It seemed to work randomly but it was super intermittent. I did some research and found the fix where you solder the front diff actuator contact points together and I verified that the fix worked using my power probe to actuate the gear. Before installing it back into the front diff. After reinstalling it I got into the truck turned on the key, and now both the 4x4 and 4lo lights are flashing, and I can't hear anything shift or click whenever I turn the four wheel dial. Any advice?
