1998 STS 3rd Taillight

The third taillight on the the top of the trunk lid is not working. Is there any problem that is common with these. We bought the car a couple months ago and I didn't notice this right away. Your help is appreciated.

Thanks,
Bryan

The only solution is a replacement. Here's some info:

"1998-2004 Cadillac Seville STS LED brake light

Currently unavailable. All 1998 to mid 2001 brake lights leak water. 100% failure. The only current fix is to replace the lamp with a mid 2001 or newer lamp. The mid 2001 and newer lamps use a better sealer. It should also be noted that this brake light is available under 2 different part numbers from Cadillac. It is available alone, or with a unpainted lower trunk close out panel. The current GM replacement part #25697411."

Try www.gmpartsdirect.com or www.gmotors.com for a replacement. You can find used ones on eBay, but I'd be sure they were off a 2001 or newer Seville.
