Default Moisture in tail lights

In the tail lights of my 92 there is quite a build up of moisture. Can someone give me some instruction on how to remove and clean these because I'm not sure where to start. Any help is appreciated.

Moisture in the taillight is a real bear to clear out. You have two options. 1) pull the tail light from the car, bring it indoors, use a hair dryer and blow it into the housing to dry it up. 2) bake the taillight in the oven or use a heat gun, pull the back from the lens, wipe it down and then reseal it.

Make certain to tun a good bead of clear silicone around the joints of the back and lens cover when you get them dried out, otherwise you will be back doing it again.

Please add your year and trim of your vehicle to your signature line. That way when you start asking questions in other areas of the forum, we all have a better idea on how to assist you. Click on "Quick Links" above, go down to "User Control Panel" and then click on "Edit your Signature" It'* pretty straight forward from there.

Thing is... there'* more than moisture in the tail lights (like there'* a green grimy substance, mold of some sort, im not really sure) so it would be optimal for me to completely disassemble them so i can get all the crud out of there. For this you say I should bake them? How long and at what temp (I think I read 200 deg F in the last thread). I see three screws when I look at the inside of the tail lights (from the trunk), are these the ones i need to remove to take off the tail lights?

Yep...take the nuts of the threaded studs and pull the assembly out. Check this thread out about breaking the front from the back of the assembly https://www.gmforum.com/t277442/

Okay. My only concern now is about this whole "lamination thing." I've been reading posts related to this topic and they say to be careful not to "delaminate." I think from what I understand the black lines are laminated onto the plastic parts of the tail lights, and that heating them in the oven for 20 mins at 200F will preserve these lines and cause no damage. From pictures I've seen, the black lines are attached to the inside of the clear outer shell, and the red and yellow lens(es) are between that and the casing. So in the end, all of these pieces should be able to separated, cleaned, and be reassembled with no damage if I heat them in the oven, correct? If so, then I'm ready to do it soon.
