May 17 Finally able to remove the casing. There isn't anything blocking the lifter. It is free to move up and down. There are 2 wires attached to the variable adjustment switch connected to the casing. One wire is blue and the other is red. The Blue wire is connected to the top of small white box. The Red wire has been disconnected from the bottom of the same white box. Please advise the best method of soldering the Red wire back onto the White box. Thank you.
