Here’s what I discovered once opening the motor control unit.
As you can see corrosion at the push button connector, causing one of the connectors to break off. Also, corrosion detected at the terminal connector (to the PCB). Lastly there are 2 desiccant packs in the box used for moisture adsorption. Both packets were saturated indicating a water entry point somewhere (I suspect at the push button). Case into Lift, I will fill update the remedy
