Re: my 3rd brake light is out, but I'm not sure how to
You dont have to. just replace your light bulb again only this time donot allow any part of your hand to touch the glass use a napkin or any mateial that is oil free. the oil causes the glass to overheat thus causing it to fail early.

I don't know what your question is but I am going to assume the 3rd brake light isn't working. This is an LED assembly which can't be serviced and must be replaced if not working. Before you do that, using a test light, and the brake pedal depressed, check for power and ground to the lamp, if there is power and ground it must be replaced. You can get one from a junkyard or ebay or your local GM parts store.
Hello, Well there is not much more it could be unless you have a shorted wire or a burned fuse. I would normally think that the turn signal canceler was bad but the 3rd brake light will still work if that is bad so I would check all fuses and for bare or shorted wires.
you can buy a cheap lamp assembly to fit the window,stick on (may not look so good)BUT $360 is $360..... its only two wires.......(car makers make a fortune out of us all.....)DID YOU KNOW YOU CAN BUY A NEW 4STR CAR IN INDIA FOR $1500 WITH A/C...BADGED HYUNDAI/TATA/GM .....YES..... GM.........
No it would cost you that in the dealer. Because they charge labor and parts, plus misc. So... what they do is replace the whole rear thrid brake light. They do this because they cant replace each LED that the brake light has. It is sold as a unit.
But make sure that it wasnt a fuse that made your 3rd brake light not work.
If not then you could go to a junk jard and buy one there and ask the dealer to install it. That could cut down the price.
Unfortunately, these are not very simple. If you have a factory high mount brake light-meaning not one in a spoiler, you have to remove the rear seats, the rear parcel shelf and then the 3rd brake light. the 3rd brake light I believe is an LED setup which get replaced as an assembly which inserts into the housing. If you need further guidance let me know.
We bought a 2000 Blazer in '02 and one day I noticed there were no brake lights, but the 3rd light on top worked fine. I did some research online and found out there was a recall on this problem due to the hazard switch on the column. I also found out if I wiggled the hazard switch a certain way, the brake lights worked. I was able to get by for awhile by wedging a 'widget' beside the hazard switch button and the hole in the column cover. This worked fine until someone would knock the widget out of place. I finally got around to having the switch replaced at a local dealer. All was fine until last week when I was told the brake lights were out again and I found out my hazard lights didn't work either. I changed out the switch assembly myself this time, and once I had it out I saw what happened. The brake light voltage comes in to the assembly on a white wire, and the first contact this goes through is on the hazard switch. In my case the contact had obviously overheated from the brake light current and melted the plastic holding the contact in place, thus breaking the circuit to the brakes. Either a poor design or too much current for the circuit to handle. Soooooo now I am in the process of replacing the four bulbs in the tail/brake light assembly with 3 watt Luxeon LED plug-in replacements. The current draw of the original bulbs was measured at 2.2 amps at 13.8 volts, times 4 bulbs makes about 8.8 amps that goes through the contact in the hazard switch whenever the brakes are stomped. The LED replacements draw .2 amp each, so times 4 will be .8 amp or less than 1/10th of the original equipment bulbs. These LED bulbs in my opinion are as bright or brighter than the original equipment and hopefully will help from burning out another switch assembly.. David
