Water build-up in the tail-lights.

There is water inside the tail-light of my car. I think there is a leak, so I went to the mechanic and he told me that I need to get the entire thing replaced. I wonder if he's telling the truth or he wants to con me? Anyone here can advise me on what to do?

 

So I guess the mechanic was telling the truth about needing to exchange the whole thing. He claimed that with that amount of buildup, the leak is probably quite large. No choice then, I hope a replacement isn't too expensive since my car is no longer manufactured and spare parts are scarce.

 

Its either not been sealed properlly or its damaged so to be honest it may well just be easier to get some new lights. On most cars its just a 10 min job to change them over.

 

Better check the tail-light yourself first. It might have been returned incorrectly, if previously replaced, or someone/something bumped it and displaced the positioning. @Flexin is right, dry it completely and check if the same issue occurs.

If there really is a hole or crack, just apply a water-proof sealant.

 

He's telling you the truth, as Flexin said you can try to remove the piece and try to find the leak, but it usually holds for little time and you'll end up spending more on the long run, it's better to replace it.

 

3dgarp is right your better off replacing it. I had it happen to my car and I took the lens off and sealed it. It worked for about 6 months once we started getting 90*+ heat, it started leaking again.
