Stop/tail lamp partially working

When I turn on my lights, the right rear stop/tail lamp illuminates. However, when I press the break, it does not turn brighter to indicate breaking. The left rear lamp works fine as does the middle break lamp above the rear door. Any suggestions?

I apologize if this redundant. I did a search, and was unable to find a solid answer. Thanks for the help!

Probably a bad ground at the brake lights.

Look at the grounds on the rear lights and make sure they have a good connection to the body.

Where would I be looking to check the grounds? Sorry to ask a dumb question, but I am new to trying to investigate these problems. Really appreciate the help.

not getting brighter when braking does indicate something is breaking.

Go to your back passenger tire over by where you fill up your gas tank, bring a flashlight along, bend down and look at your chassis behind the tire. You'll see wires coming out from the chassis leading to the backs of your lights. Check the integrity of those wires (there should be about 2' worth) and ensure there aren't any breaks in the wires. From the back of your truck, you should also take a screw driver and unscrew the two screws holding that light in, check the integrity of the bulb, and the contacts within the housing. Best of luck.

Here was a pic of my wiring a few years ago when I had the same issue.

I am in the process of running ground buses back to the battery/frame to eliminate this exact issue. I am sure it is overkill but lights are so darn important

While I agree it could be a bad ground, it's worth checking the bulb. If I'm not mistaken it should be a dual filament bulb - with one filament for brake and one filament for running lights. The brake filament could be out.

Just read it's a 97... In that case I don't know if it's a dual filament

or might not be screwed in properly (I've seen that as well)
