1999 JGCL running break lights not working

I have a 1999 Jeep Grand Cherokee Laredo and my night time running brake lights and third light won't turn on. When I press on the brake the two bottoms ones turn on, but when I release it they don't dim back down they just turn off.

I have checked my connections, fuses and bulbs (bulbs are brand new and were working a few days ago when I put them in, and are the correct bulbs)

Anyone have any ideas on what it could be?

Welcome to the garage.
Many times the problem are the light sockets. Try to bend the small copper tabs out a little bit. For the third brake light, if the light bulb is ok (check with ohm meter), i would check with a voltmeter to see if voltage is available at the socket when braking. If it is, then check the ground side with an ohm meter.

I will have to check which brand it is, but since im in Brazil, i wonder if you could get the same ones. There is a vendor on here who gives discount, have a look in the vendor section.
