I have a 2002 blazer and the rear brake light over the windown is working fine, but the housing it cracked badly, needs replacing, any ideas on how to do this and where to get one maybe? How is the wiring for the light done, any suggestions, thanks.

 

Dealer... Possibly in the aftermarket, but I haven't seen them.. Junkyard would probably be the best.

The wiring goes through a rubber bulkhead into the interior above the rear of the overhead trim directly in front of the rear hatch.

 

yeah i have been searching ebay and all kinda stuff for our blazers and haven't found anything..good luck...i would think its a junkyard idem..

 

LMC truck carries the 3rd brake light. It's all one piece though, runs like 100 bucks.

 

You should be able to find one from a junkyard or on ebay, and as far as i know the wiring is just a plug, otherwise a quick solder job matching wire for wire should be easy to do. Here is a link to an eBay new product (and any third brake light from a 95+ blazer,bravada,jimmy or suburban/tahoe should work).
