Water in tailight

[olddsmer]

Hello to all and Happy Holidays.
I have a problem I can't figure out. Water keeps building up in the driver side taillight assy. I have pulled the light housing out and inspected it for cracks or holes to no avail. All lights seem to be plugged in properly. I empty the housing out, re-install it and a month or so later, there will be an inch of water in the bottom. Has anyone ran into this problem on a 93 Talon? Any suggestions or advice will be appreciated.

Best Regards

Either there's a sealing issue with the sockets, a crack/missing piece somewhere in the folds, or the adhesive has broken down or was never present and over time, it finally presented itself.

Take a good look. Remove assembly and bulbs, get a bin of water, and start soaking various parts of it to find where it enters.
Fix or replace.

or drill a drain hole

I had a taillight doing that and once I found out it was the seal leaking I just heated it up with heat gun while applying pressure and was able to get it to seal back up. It didn't leak for over a year then sold the car out of town so not sure how long it held up.

One easy way to locate a leak would be to remove the light, plug up (or tape up) two of the three socket holes, and fill the light with water through the third one. Where ever water leaks out, that's where it's getting in.

Has there been major downpours where you live, washing your car often or live in a climate area where there is a lot condensation on glass from the cold weather? I had this problem with my BMW headlight where condensation would build up after a car wash or heavy rainfall. Turned out it was an access cap on the back of the headlight that had a rubber gasket that was torn allowing the water to come in.
