The adjustment of the brake light switch or it could be bad. the brake lights can work fine and the part of the switch that works the cruise doesn't The swiches that control it from the steering wheel can losse connection in a part called the clock spring. Vacume connections can effect the cruise but yours is likly cables less therefore doesn't work the cruize.

cruise control best let garage check out,here are few things to check,check fuse and check to see if brake lights dont work.check brake light fuse if fuse okay brake light switch could faulty or bad connection then brake light will reset cruise control you apply brakes.if all is good problem could be speed sensor or accelerator pedal to ecm.you need diagnostic euipment to troubleshoot.

take a test light and make certain your getting power to the socket. could be a bad socket

They are part of the dome light circuit, so if the bulbs are ok you'll have to check the wiring fuse and switch.

I have a 2001 volvo v70 wagon. My lower brake lights are not working but my 3rd (top) brake light works fine. I replaced the bulbs checked my brake light relay checked all fuses and ground wire and all seems to be fine, but the lower brake lights still doesn't work. I need Help!

"B" lights? You mean brake lights? Could be the brake light switch. I'd start there. It's fairly easy to replace. To check the brake switch, remove it, and see if the piece that pushes in is stuck be gently pressing on it and if it doesn't press in, gently pull on it to see if comes out. If it doesn't not freely move, that is probably your issue. The brake pedal assembly presses it in when you step on it. For a 2004 Forenza, the part # is 37740-85Z22. If you have a 2005 - 2008 Forenza, the part # is 37740-86Z21. Both are under $20.

The first step is to check the bulbs in the tail lights. The brake light switch (on the brake pedal) is OK, as the center light works.
