This game is giving me a headache. I literally just got done fixing red's jaw for the second time and it is working perfectly only to play a game and have the bulldozer not go up in game mode (works in test mode). Both proximity boards for Ted register in switch tests. I believe the issue is the wires going to the blade interrupter board, when I touch them or wiggle them, the dozer up switch is registering. If dozer up is registering, I'm guessing the game thinks the dozer is up and that's why it won't rise during the game. I ran out of time last night, but hoping reseating the wires in the connector will fix it. Very strange that all of a sudden the wires are causing switch activation, though I was in there messing with red quite a bit and may have pulled something.
If that doesn't fix it, guess I'll start reflowing solder on the board.
There's a few threads on this, has to be relatively simple to fix, but frustrating to figure out.
