I have an 85 T/A and have a problem with the rear lamp cluster's getting a build up of damp inside.

I have many times removed them, dried and resealed to prevent any water ingress, no success.

Any feedback would be gratefully received!

 

Anyone, Please?

Find it hard to believe I am the only one who has had this problem, I have tried in the search function but I may be missing a thread on it?

Many thanks in advance.

 

I know my Dad's car gets some condensation inside the taillight, but that's because the lens has been cracked. What's probably happened, IMO, is that the bulb holder isn't sealing to the back of the housing, or you have a crack around the edge where the lens is bonded to the black half of the housing, those would be my first guesses.

 

Thank you for your reply.

I think its worth me changing the seals around the bulb holders although they look pretty good it's worth a go to eliminate the possibility .

I think also I will have to try and replace the housings.

 

You could also test your current housings by submerging them in a tub of water lense side up or by filling them with water, lens down, and seeing if they bubble from anywhere, or drain from anywhere other than the bulb holes, respectively.

But definatly try the seals first

 

Yes, thanks, I have filled them up with water and the only place it comes out is the 3 small drain holes at the bottom.

I dried both out about 3 days ago , put them back and one is misted up again
I got them warm enough to get rid of any damp.

I think I will get some newer one's I did hear that the first year these style were used they got dampness trapped between the window surface and the black lattice what makes that grid style effect on them which was improved on later cars but no one on TGO has as yet confirmed this.

Its does not help having a damp environment here in the UK!

 

Though the following concerns the parking lenses, the issue may be the same:
