Remove the clear cover from the rear tail light housing?

[ElectricStu]

I had a lot of water and some dust behind the taillights (2014 Model S P85+, no longer under warranty). So I removed them and dried them out.

At some point in the past parts of the tail light stopped working, likely due to the water ingress. I recon I *might* be able to fix this, *IF* I could access the electronics assembly behind the clear (PMMA?) plastic housing. However, at first glance, it seems to be glued quite well to the black ABS plastic housing.

Anyone here any experience/knowledge about this??

Yes they are glued together, usually quite well but sadly not sealed quite well enough to stop moisture ingress.
Trying to pry them apart or otherwise cut the sealing glue is usually an effort in futility.
You can try but I'd have a new light ready as a backup when you break it.
