I found an AMETHYST Crystal that is about 2 X 2 inches.Digging about a foot below, I found a 2 inch long Double Terminated Quartz Crystal.Snoqualmie Pass.Hanson Creek, WA.
Just take it back and ask nice that you are still having trouble with the switch they fixed and they should warranty there work.
I would say that you could try to take them to small claims. Show what you paid for the repair the first time. Take pictures of the car and keep the piece that fell off and get estimates from a different place to repair.
