Of course you should check the bulbs first. There is a fuse for the brakes in the fuse panel on the drivers side of the dashboard, about halfway down where the door would cover. The fuse descriptions are on the fuse box cover. If that fuse is good, there is a switch that operates the light. It is located under the dashboard where the brake pedal contacts the metal frame. It is a small black switch with a red button that is screwed into that metal frame. It is a bugger to get to, but I have had to replace it in my 1996 Dodge Ram 1500, and my 1993 Jeep Wrangler. Its a cheap part, but hard to get to.
Often these are accessed thru the trunk; have you tried that?
Check the brake light switch on the brake pedal
Bad fuse or bad brake light switch.
If you mean the brake lights are stuck on, then check the stoplight switch located on the top of the brake pedal.
The white parts of the tail lights are the reverse lights.
The cruise system shares fuses with the engine and brake lights. If the car runs and the brake lights work, it is not a fuse.
Check stop light fuse Check bulbs double filamented smaller for brake lights Check the operation of the stop light switch Check socket for corrosion
Inside the trunk there is a turnable thumb screws where the brake lights are. Twist screws off and the brake light pops out.
If the brake lights do not work on Chevy Venture van 2000, try to disconnect the brake switch. Then short the two contacts of the connector to check if the brake lights are now working.
check the fuse, brake lights have their own, & check the brake switch at the top of the brake pedal
bulbs blown on high side or wiring shorted
On a 2000 Dodge Ram, "no bus" means the communication network between modules has quit working. Any module on the network or the wiring between them can be the cause of the malfunction.
