The tail light fuse is under the rear seat on the drivers side.

Motor relay circuit this is for the ABS, you will need ot restore the third eye brake light and check fuse in the engine junction fuse box, (cigarette lighter fuse) make sure it didnt open

UNDER THE HOOD IS ANOTHER FUSE BOX FOR THE LIGHTS.

This is the part you will need to replace.

you need to check to make sure the brake lights work, also the brake light switch is the switch not prake-brake switch, the switch is located above the brake pedal no the bracket that holds the pedal.first thing is to check all your fuses.

need to know if your third brake light up high is working or not.if it isn't,you need to check the brake light switch on the brake pedal with a test light,one side hot all the time,the other side should turn hot when brake pedal is pushed.

2002 ENVOY BRAKE LIGHTS WONT WORK

On the brake pedal under dash is a switch that is actuated when pedal is depressed. depress pedal and check that the switch is being depressed. if not the switch can be adjusted by a nut on the neck of the switch. Good luck!

CHECK MASTER CYLINDER

There are two fuse boxes on a 2002 Envoy One under the Rear seat on the drivers side and one under the hood on the drivers side.
