Question about Cars & Trucks
My rear brake lights don't work. I replaced all the bulbs & the only the 3rd brake light works on my 2003 pontiac montana van.

If the 2005 Montana is similar to the 2001 Montana, I have a solution. First you'll need a hexagonal wrench (the 6-sided L-shaped wrench). The tail light assembly is held on by two screws. You'll need the hexagonal wrench to remove them, because a normal screwdriver won't do it. I also had to use a conventional adjustable wrench to get the leverage to turn the hexagonal wrench, because the screws were in there pretty tight. Once you remove the two screws, the whole tail light assembly should come off. Mine required a little force and I had to play with it a bit, but it came off without a lot of work. There will be one set of wires that connects the tail light assembly to the rest of the minivan--try not to damage that set of wires. Once you get the tail light assembly off, you'll have to take apart the assembly that actually holds the lights. No tools should be required. It's held on by four plastic catches. Just undo the catches (easier said than done, but still not too tough) and it comes apart. Then you can pop out the old light and pop in the new light. Then re-assemble. For me, it went back together much easier than it came apart.

check the ground in the fuse link also take out the rear tail light lens and make sure you don't have a broken or damage wire on the socket itself

Check for power and ground at the two panel lights. GM uses a cheep circuit board design, they overheat and corrode on the other side of the board. not serviceable.

Tips for a great answer:
Check the Amps on your Fusebox for your brake light if the correct amp measurement is installed for the break lights then consider using a larger bulb or a bulb that can handle more voltage. most likely incorrect voltage is going to the bulb this is normally fixed by adjust the fuse amp amount to be lower or higher or changing the bulb voltage size
