AH-ha! You're welcome, and that busted-in-the-terminal-crimp thing happens even with good cooper alloy wire. They get nicked and/or harden when crimped and snap over time. Vexing problem. Your fix is fine, I've done that *or* flowed in solder and have not had to talk to the connection again.

You say the brown wire was warm, I dunno, if it did not burn you there may not be a problem. Have to look at the wiring diagram to see what load is on it and then decide.

When I rewire an headlight or horn circuit for instance, I usually use 14 Ga. instead of the 16-18 usually in there. If the run is more than a few feet there is a small but measurable difference in power transmitted. Point is that what power is not transmitted ends up as enough heat that you can feel it in the wires that are working near rated levels. You'd be able to feel heat in the wire from about 30 deg C (86F) and up. Auto wiring is usually rated for substantially more heat.

THIS LINK has a chart showing what gauge wire to use for runs of how long and if you look up the SAE specs they refer to, you'll see what the related performance criteria are.

This reminds me, I have to call my local dealer about a parts order.

PostSubject: "GMSPO Carline Parts Catalog" & "GMSPO Standard Parts Catalog"   Thu Dec 28, 2017 3:41 pm

I'm trying to get set up to be able to repair terminal "opens" like the one at the Lamp Control Module that caused my tail lights and dash lights to go out a couple months ago.  My repair is still holding up but I expect a failure sometime.

Book 2 of the Factory Service Manual (1996 Riviera FSM) page 8A-5-12 calls out the:

J38125-A Terminal Repair Kit

J35616-A Connector Test Adapter Kit

Supposedly these can be ordered via the "GMSPO Carline Parts Catalog" in "Group" 2.535 or in the
"GMSPO Standard Parts Catalog" "Group" 8.965.

I've tried to search-engine this catalog but don't find anything promising.  I've gone to GM parts direct to try to search for this "Carline Parts Catalog" but find nothing there either.

Does anyone know where I can buy these kits?  I looked on ebay for the terminal kit that Albertj pointed me to in  an earlier post of this thread, but after looking at that kit, it didn't appear to have the specific terminal style that failed at the Lamp Control Module - the one that I'd like to be able to replace.

Thanks for any help.

The J3-such-and-such are Kent-Moore numbers, those kits are sold under the same base numbers for different folks (GM, Sumitomo, Lear, etc.) You may be able to get the GM or other dealer parts desk to sell you the terminal you need as "shop supplies."

Ok I looked more into it after work and what happened makes sense, all four lights were blown in the back. One had moisture in it cause I have a cracked tail light and it blew all four. I'm guessing the moisture shorted it out and caused them to blow. Thank you to all who gave input, I appreciate it a lot.

the right side of my tail light keeps getting water in it badly, i cant tell where or how its getting in? replaced right side bulbs monday and this morning they were already blown out. lots of water inside

cant see any cracks or a noticeable spot that needs to be sealed up?

also my third brake light has been out for awhile, went to replace with brand new bulbs, left side worked but right side still wouldnt light up... so i just took the left one out and been rocking with no third brake light for like a year now lol

You will need to remove the entire taillight housing from the car to find and fix this problem. Take off the rear wall trunk trim panel as if you were getting to the bulbs and remove all the plastic wingnuts off the studs, then push/pull the assembly toward the rear, away from the car.

*Then* inspect the assembly. You can seal it up with silicone caulk.

Might help to shine a light into the assembly thru the lens and look at it from the reflector side to find the crack. Most likely it's a seam, possibly it is impact damage.
