there was a recall on the hazard light switch that caused the rear brake lights (minus the high mount 3rd light) to stay on. the hazard lights and turn signals still worked. there was only an electrical malfuntion in the hazard lamp switch on the steering column. go to your nearest dealer, they will fix it for free and it only takes about 1/2 hour
The development of the first brake light is not actually known. They appeared in 1905 but took a while to catch on. By 1928 11 US States adopted brake lights
The brake lights and signal lights are tied together in the signal switch, also known as the "multifunction switch".
Try looking at the wires at the top by the hinges of the boot lid. the wires are inside a rubber sleeve and they are known to break, hence no brake lights
The center high mount led brake light unit has been known to go bad.
All brake light switches are mounted directly behind the brake pedal on a bracket that holds it in place with a electrical push pin that moves in and out when the pedal is depressed.If you have no brake lights but,your tail lights work with your headlight switch on for parking lights the brake light switch needs to be either adjusted and if after this if this does not correct the issue,replace the brake light switch.Most auto zone,advance auto parts,napa will carry this part and very easy to replace.Too easy.Note make sure the bulbs are known to be good in the tail lights by looking at the elements inside and not fried (wire is not solid from left to right side in the bulb) If only one side is not working it would be the bulb,however if both are not the info above answers that.
There is a bushing that the brake light switch rest against when the brake pedal is not depressed. They are known to break. You can get a replacement bushing from any Honda dealer for around $5.00. Just tell them your brake lights stay on all the time and they will know what to give you.
the fuce for the brake lights is located in the kick panel, witch is also located on the drivers side left were your feet rest when you drive, also this is known as the fuse panel. you will need to remove the 3"x3"cover in order to get to it
Encoder motor (transfer case motor) needs to be replaced it is on the transfer case. the gears strip out inside it, or the shaft breaks. you can get them on e-bay. really easy to change.
Nonfunctional LightsI'm not familiar with your 2002 Gran Prix, but the problem you describe is universal to all vehicles.The fact that the "third" brake light [in the rear window package tray] IS WORKING, indicates that the brake light switch IS WORKING properly!!!!!That suggests that the reason that the other two brake lights are not working is that there is an "open" condition in the wiring circuit to the other two brake lights. This is confirmed by the fact you replaced the lamps [bulbs] in those other lamp holders with known good lamps.There could be several causes for an open circuit, but the most common include:One of the connector plugs in the wiring harness to the brake lights has become disconnected, orCorrosion has built up inside of one of the connectors [one that feeds both brake lights, which will be in the circuit "ahead" [upstream] of where the wiring harness "splits" off between the two brake lights].Very remote is the possibility that the ground wires on both light assemblies has been disconnected, cut, or corroded.
The most common reason is a bulb failure. If the bulb is known working, or replacing the bulb does not cure the problem, look to the fuse, switch and wiring.
If the fuses and bulbs are okay you may have a bad signal switch also known as a multifunction switch.
Had the same problem with my 2000 Dodge, all it was was low brake fluid???? Don't know if that will help. I HAD SAME PROBLEM WAS FIXED WITH A SIMPLE FUSE REPLACEMENT FOR BRAKE LIGHTS ABS AND BRAKE LIGHT WARNING LIGHTS WILL COME ON WHEN FUSE IS BLOWN FOR BRAKELIGHTS do you still have brakes if the light are on constantly have the brake and abs relays replaced. I had the same problem on my 99 ram 1500 4X4 Another thing to consider is whether or not the speedometer works at low speeds. If it doesn't read anything until about 25 mph, check the sensor on the top of the rear differential. It should show about 750 ohms if it is good. These are a known issue on Dodge trucks and generally show as an open circuit when they are bad. It is about a 10 minute job for the diy mechanic.
