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!
I had this same exact issue. It's the brake relay in the left hand rear cargo compartment. if you have the rear fog light option that relay will serve as a replacement until you can get the correct one for your brake lights. Swap fog relay into that spot, order a new brake light relay and install in original spot.
These cars have a known issue with the relay in the BCM, Brake Control Module. If you go to the Volvo dealer they will probably replace the relay it for free. They are very common and only a few quid.

I would guess the brake light switch is going bad. it is a push button type switch mounted to the metal arm which transfers motion from the brake pedal to the master cylinder. generally unclips or unsnaps and then unplugs from wiring. put a rug down on the dry floor next to the open driver's door. get a flash light and look up underneath the dashboard. follow the brake pedal arm up a few inches and you will see it. that is on a normal car, who knows how the swedes do it. they could drive up the complexity and cost by installing a pressure switch into a brake line somewhere which would double as a brake failure alert. first thing i would do is google volvo brake light switch and see what it looks like. then check under the dahsboard and see if you see it there

Replace your brake light switch,also just replace the brake light fuse,sometimes they can have an very small crack in it,they you cant see.

In my own personal experience, you should first adjust the nuetral safety switch, it controls the reverse lights. After that, remove the jaw clip from the back of the tail ight, clean the connections, and the take a thin pick, and close the 2 metal pins together in the different sections of the jaw, with enough space between them to plug them back in. The connections inside the clip tend to expand away from the printed tail light curcuit over time.
Testimonial: "Hey, thanks for the tip! I will try it! every time I step on the brakes the "bulb out" light goes on & it's driving me nuts! thanks again."

Welcome to Fixya
If you already tried the paper clip method then most likely the tail light assembly circuit board films or wirings that is having the problem. Use a test
light to check for power at the tail light assembly, while you have the
switch bypassed.
Thank you for using Fixya!
