The high mount brake light fuse on a 1998 Mazda B4000 may not be shown in the owner's manual because it is often a shared circuit with other lights and accessories.

That being said, the fuse for the high mount brake light is typically located in the engine compartment fuse box or under the dashboard fuse box. Check your owner's manual for the exact location of the fuse box in your vehicle.

Once you locate the fuse box, look for a fuse labeled "STOP" or "CHMSL" (Center High Mount Stop Lamp) or "BRAKE" that is related to the high mount brake light. Use a fuse puller or needle-nose pliers to remove the fuse and check if it has blown.

If the fuse is blown, replace it with a new fuse of the same amperage rating. If the new fuse also blows, there may be an underlying issue with the wiring or the high mount brakelight assembly itself that will require further investigation by a qualified mechanic.

check brake light switch first if all 3 lights are out-- located under dash at brake pedal bracket

There are three fuses involved.
There is a 25 amp fuse before the brake switch located in the fuse box under the hood. Then there are two 15amp fuses after the brake switch in the box inside the cabin. One is for the lower brake lights and the other is for the high mount light and the trailer connector.
You would need to know if the 15amp fuse for the lower lights has power when the brake pedal switch is applied.

Hi, you need to test if the power is coming to the plug for rear brake light. If the power is not there that is your first problems. Also may have earth wire problem.

Some of these had two fuses for brake lights. One for the top/center stop lamp and another for the rear left and right brake lights. Usually one said "stop" and the other said "brake" and one was in the underhood panel while the other was in the dash fuse panel. It's not uncommon to blow a brake light fuse [LR and RR] if you tow a trailer but some of these had seperate fuses for the trailer lights also. If you have a test light check both sides of the two fuses for power [ignition key on] while stepping on the brakes. It should at lest narrow your search a bit.

if no brake lights are working,not even the high stop light in the rear window,And you have checked the brake lights fuse with a test light,it will be time to check the stop light switch located on brake pedal under dash.

check the brake light switch located under the dash,located above the pivot point on the brake pedal arm

ljones, Did you check the "VEH stop" fuse in the left side instrument panel fuse box. There are 3 stop light fuses, 1 for all the stop lights located in the under hood fuse box. 2 in the left side IP fuse box. 1 for the upper stop light and 1 for the lower stop lights. The fuse box in the IP is where the upper and lower stop lights split. Let me know.

1ST THING TO CHECK IS THE STOP LAMP FUSE . FUSES LOCATED LH SIDE UNDER HOOD. THIS FUSE ALSO POWERS THE ACC. CIRCUT IN TRUCK. ALOT OF TIMES, LAP TOPS, DVD PLAYERS ETC. OVERLOAD CIRCUT & FUSE BLOWS.
