Blinker fluid. I hate it!!! Just this summer I replaced the black seal around the driver's side tail light assembly and the stupid brake light portion is filling with water again. Probably doesn't help that the car has had to spend the winter outside so far, but still...

I just had to vent.

I hate blinker fluid you realize.


Seriously.

 

I think they even came from the factory that way :-)

 

Dang, these cars even have blinker fluid?

Man...so high-tech!

(sarcasim if you cannot sense)

 

Manning, my tail lights did the same. Did not realize it until a couple of guys at the last autocross told me. Drill a small hole in the bottom inside lense on each side. It drains the water out, no more accumulation.

 

I went to a dry sump for my blinkers. The bulbs don't last as long but it's worth it.....

 

Yeah, I've been debating whether or not I should do that. It just seems to circumvent the problem though, not fix it.

 

What? They're not supposed to be like that?


I just put fish in mine, so it would at least look cool.



Just kidding
Seriously though, usually they fill with water when the drain on the hatch lock mechanism is plugged/disconnected, might want to check there as well.

 

The gaskets for the hatch pins leak and let water run down on top of the light housing. Then the water seeps inside the light.

Mine had the blinker fluid delete option from the factory, saves about 8 oz.

I agree with the hatch pins seal though.

 

I witnessed the conversation. It's the truth.

 

Hmm, hatch pin seal. I'll be bummin if it is that, because I replaced mine, well the car's, a couple years ago. Somehow I think that may be it though as I did notice a little bit of water back there, which I initially dismissed as having dripped in off the hatch when I had it open.

Thanks for the ideas

 

Try getting a helper to hose it down while you lay inside with a light and watch for leaks. I went out during a heavy rain and it didn't take too long before I saw a drip. But if you replaced your seals I doubt that's it.

 

I agree. Fix the REAL problem. Drilling a hole in it is a cheesy way out of dealing with the issue.

Some others have already mentioned some good points to look at. Hatch pin seals/drains, flooding the outside of hatch with a hose to see where water is getting in at. I've got the glass separation issue like most have also. If the spoiler drains are clogged up (happens frequently to me), than water will back up inside via that glass/frame lower connection, and drain to wherever. Maybe? I try to keep those drains clear, and have applied black silicone seal along the inside of the glass to frame, till I can ever get around to re-doing the hatch glass to frame seal. I've been staying pretty dry so far doing this. The hatch pin rubbers have been gone over and resealed also.

 

Fix the real problem probably will involving getting another car other than a 944....
