Top malfunctioning like rear glass has already moved when it has not


Thought a video was best.

Something is wrong with the convertible cabriolet top where when opening the rear cover tries to flip open before the rear glass even moves so it stops the process a couple of seconds into opening if I manually open it and then go to close it that's what the video shows and I have already checked all the fuses And even switched around similar relays but I do not know which relay is actually for this process. I have also unplugged the battery for a week while the top is in the completely closed position thinking it would relearn or reset but it did not. There is a proxy switch in the rear cover under the driver's side chrome oval where rear glass goes in and latches but seems to click but I have not tested it. The car is out of warranty and I literally just got it paid for a week before this happened. Any help would be much appreciated.

Let me know if video does not show; when I put the link it automatically embeds the video.

This was the broken switch I found (after noticing a small spring that looked like it was from a pen in the trunk area)



Damage shown from letting kids operate the top and went back and fourth rapidly.

Switch location is driver side where rear cover slides into a hook/channel near back seat and not the one under the chrome circle on the cover.

Bought the genuine part for eBay for $25.

also double check the alignment whee the cover goes into the 2 chrome circles as this was also causing an issue (unsure if before or after replacing the switch) Packaging.
