I have repaired lifts from hurricanes
I had some from hurricane Katrina I removed the batteries and unplugged and removed all of the electronics ie accelerator , control modules etc then blew out and let dry for ten days
Made sure no moisture in any motors or controllers then put together out of five I had one that I got to work without needing parts
It's a crap shoot either way especially if battery was in unit and plugged up
The very least you will probably ending up replacing several cards and controllers and maybe a few motors not an inexpensive
