Fog / moisture in left tail light housing

[TEG]

Now that it started raining in my area, I notice that my left tail light is getting very damp inside. Only this one housing has the problem. The right side is OK, the headlights are OK, the middle rear sections are OK. Just the leftmost rear housing looks like this now:

Compare to the right side:

I don't know if it has anything to do with it, but I recently had my charge port serviced, and it is located on the left side just in front of the (now foggy) tail light.

I think other Tesla models also had moisture problems in some light clusters.
Anyone have suggestions on how to fix this myself? I would rather not leave my car with service to debug this problem.

I noticed this somewhat related thread about Model S:

Tesla still delivers cars with moisture in reverse light housing!

What I need is an aftermarket cluster with amber turn indicators !

No diagnosing should be needed. I had the same issue on delivery and they replaced the tail light no question asked. I showed them a picture similar to yours. It’s clear their is water and moisture in your taillight.

Same problem.... was fixed via the mobile service dude

Take it to service and get a new tail light.

Should there ever be condensation in the tail light?
I have some in both when I pull into garage after cold, rain or snow. It’s gone by the morning.
Thanks

I don't have fogging like the OP, but I did notice small amounts of water inside both tail light housings after driving through heavy rain today. Is this normal?

OP, please have Mobile Service swap that out ASAP. It looks terrible, so your rolling Tesla billboard is currently advertising the wrong message!

Nope. Light housings are sealed and should never have water/moisture intrusion. Call the service center to have them replace it.

Also + OP, examine your light housings for any signs of cracks. If they find the housing is cracked from outside impact, they won’t cover replacement of the light housing
