I replaced the bulb in the back window brake light but still not working?
Climbed in the trunk underneath the window, found the opening, took out the old bulb and replaced, but still does not come on when I apply brakes, is there a fuse I need to check maybe?
Re: I replaced the bulb in the back window brake light...
The third brake light is powered thru the brake switch but does not go thru the turn signal switch. You may need a wiring diagram to know where to look next.
the covering often is just a press fit on... then remove that... look on each side to make sure there are not any screws... then the bulbs can be replaced from there.... or you may want to climb into the trunk and look up... you may be able to change them from there

Please take a moment to rate this solution.. thanks
do your turn signals work? I believe the brake lights go through the same wiring harness as the turn signals,you could have a bad turn signal switch.also did you check for power at the brake light switch?you may also want to take a look at the wiring in the trunk
I dont have a diagram but the brake light switch has to feed the turn signal switch, Either that wire has a bad connection, or the turn signal switch is bad. Jiggle the turn signal lever and see if the brake lights try to work.

Open the trunk and you will see screw underneath the carpet.remove the screw and push the light out.remove the burn bulb and replace with same model # . If the bulb is dual (5W-15W) will have different high on the locking pins. place the light back and tight slightly.DO NOT OVER TIGHT, WILL BRAKE THE KIGHT
I just solved a similar problem on my 2003 Saturn. The tail light assembly had gotten wet on a stormy night with the trunk open. There was no problem until the weather turned cold. After looking at the fuses, relays, brake switch etc. I got my trusty voltmeter out. Testing the voltage on the light blue wires in my tail light connector I found the required +12Volts for the brake lights when the brake pedal was pressed. Checking the lamp sockets I found the 12 volts was still present when the brake pedal was pressed.
The water that leaked into the bulb connectors (right and left) and spread the contacts when the water inside them froze! Blowing out the water and pushing the contacts back together solved my problem! Lesson...Keep the trunk closed when it's raining hard and dry out the bulb connectors if they get wet.
The easiest way is to open back trunk open any coverings or carpet pull it back to gain access to the bulb socket once you see the socket twist it counter clock wise and remove remove the bulb and replace with new one once installed have someone step on your brake pedal to confirm working then put upholstery back and you =have completed changing your brake light bulb.
The procedure is as follows:--
Working from the trunk: 1. locate the 2 retaining knobs (doohickeys that you fasten the trunk cargo net to) for the Hard plastic trunk liner near to and inside of the rear light assembly. Unscrew the knobs. 2. Pulling back the plastic liner, locate the 4 studs (threaded posts). 3 will be located vertically in a line, the fourth, outboard and lower. Using a 10mm wrench(small), remove 3 of the 4 nuts fastening the light assembly to the body. DO NOT remove the lowest nut of the 3 in a vertical line, as this does not fasten the light assembly. DON'T LOSE THE NUTS OR WASHERS.
Working from the rear of the car: 1. Hand pull the light assembly from the car body. 2. Remove bad lamp. Twist lamp socket and pull out of assembly. Pull lamp and replace with #3057. Reassemble: 1. Test light prior to reassembly. 2. Ensure Gasket material for assembly and studs is intact, this keeps water/dust out and dampens movement (prevents rattling and increases the life of lamp). 3. Use Reverse instruction for reassembly. --------------The taillight/backup light/license plate light assembly is separate from the brake light/turn signal light assembly on the Buick LeSabre. No matter what rear bulb you have to replace, you must access the trunk area to do so.Open the trunk of the Buick LeSabre.Locate 7 nuts underneath the trunk lid (3 on each end of the trunk lid and 1 in the middle). Remove each one using a nut driver.Manipulate the trunk lid at chest level and gently pull the rear taillight assembly slightly away from the trunk lid.Locate the burned out bulb sockets and then remove the bulbs. Insert the new bulbs into the socket and test by turning on the lights before reassembling.Replace the tail light assembly by aligning the studs inside the predrilled holes in the trunk lid. Refasten the 7 nuts.Remove the cargo net if applicable to replace the brake and/or turn signal light.Unscrew the plastic wingnut that the cargo net is attached to. Pull back the trunk liner.Remove the 2 plastic wingnuts under the trunk liner.Pull the brake light assembly outward from the back of the LeSabre.Locate the socket of the burned out bulb and then turn counter clockwise 1/4-inch to release it from the assembly.Remove the old bulb from the socket and replace with a new one. Test the light before reassembling.Thanks. Keep updated for any more query. You can rate this

check where the wires go from the inside of the body to the out around the gromet. I did run into one that the wires rubbed. Also if the light are on the trunk lid check where they go through the trunk latch.
2004 Rx8 kept blowing 15amp brake light fuse. Solution: wire going to rear lights was worn and frayed where it feeds through the left trunk lip on left side of trunk. This can be seen when you open the trunk lid. The wire routes by the trunk lid hinge. If the support connectors come loose, the wires are crunched by the hinge or lid. Re-splice, insulate, zip-tie, replace fuse and replace any blown bulbs.
1.) unplug the connector in the trunk (its a small white plug running up to the third light, there should be a small clip you squeeze).
2.) remove the 2
gold-colored screws from inside the trunk. They can be seen from the
trunk. 1 is thru the larger square opening where the wire connects to
the 3rd brake light. The 2nd is on the right side thru a small
(screwdriver width) hole covered by a piece of foam tape stuff I had to punch me screwdriver through the foam to get to it.
3.) after removing the 2 screws, go inside the cabin and the brake light housing pops up.
4.) disconnect the bulb from the housing while inside the cabin (I had to do this with me two forefingers since the housing only pops up and inch or two).
5.) in the trunk remove the wire and bulb. (it's about 5 inches long. the wire from the connector to the bulb socket)
6.) reverse steps to install.
It is a pain and reqiuires a bit of time only because there isn't a lot of room to move around, but it beats taking it to the dealershio!
I had the same trouble with mine. My husband took a test light and checked to make sure there was power going to the push button. there was power so he climbed threw to the back and popped it from the inside. we found out that the wire in the back was being kinked by the tailgate. so it was shorting out. He just ran a new one and now it works great but still my key dont work lol but atleast the button does. give that a shot i hope it works foru too
