    The Trailblazer (my '02 anyway) has TWO fuse blocks. Naturally the on under the hood but there's a second on under the drivers side back seat. There you'll find the, probably blown, fuse that controls your brake lights, including your third brake light and cruise control. ;-)

    Correction, this fuse shouldn't affect your third brake light, I'm sure it was already working, sorry. Good luck, hope above advice helps.

    There is a SECOND fuseblock under the drivers side back seat, THERE is where your fuse is. ;-)

Had the same issue in the spring. Replace the turn signal switch. A general weakness in the switch in these years. Replacement solved the problem in my 97 Lumina.

Brake lights don't work but taillights do


This can be one of several things. First thing I would check is to make sure you don't have a blown fuse for the brake lights. They may not be on the same fuse as the taillights. If no blow fuse then check the switch that touches the metal bar on your brake pedal. This switch closes when you apply the brake. Use an volt meter to make sure the switch is shorted when you apply the brake. If both of these things are ok then you will probably have to take it to a dealer.

When I turn my lights on my tail lights work but when I hit my brakes the don't light up I have a 2001 vw beetle????


the brake lights don't light up or the taillights don't light up? the brake lights are brighter than the tailights so the tailights won't show up whenbrakes are applied. if no lights work when brakes are applied then check for a bad ground at the light assembly.

Brake lights don't work but third brake light does


I believe the flashers are on a different circute. It sounds like a bad ground.....or one of your taillight sockets is bad. I have a cavilier that had the same problem. I went to a junk yard and found some light socket s and swopped them. So far it has been working. The third light has its own ground. tail light sockets need to have a good ground, some times the ground from batt. to block, ground frome block to frame can be bad.
Think "ground"
Don't try and buy new sockets , unless they are just like the fasctory sockets. getting the entire tail light works good. Find the main tail light, the juce comes to it first, then passes to other side. Check that dide frst. work your wat over to other side, if u cant find a problem, work your way to the front and find out where the lights are grounded.
good luck

2006 santa fe, rear brake lights will not go on


Check fuse number 14 in the passenger compartment fuse block it should be a 10 amp fuse. If the fuse is good you will need to find the brake switch under the drivers side of the dash. It will be mounted on the brake pedal lever. You may need to remove a trim panel to gain acces to it. There should be 12 volts on the green wire all the time. The green with black wire should have power when the brake pedal is depressed. If there is no power you will need a new brake switch. If there is power than yu will need to pull the taillight assembly and check for power at the socket. If the third brake light is working than you can skip all of the above and start by checking the bulbs. It is still possible for all the bulbs to be burned out so it wouldn't hurt to at least check one of them to see if it is good. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Brake lights dont work Bulbs are good and brake light switch is good


The power flow for the brake lights goes like this: Fuse ->Brake switch -> Turn signal switch -> Rear lights. The only difference is, if you have a 3rd brake light in your rear window, that gets its power directly from the brake switch. It does not go thru the signal switch first. So, if you are having a brake light problem, and your fuses are good, check the 3rd light in the rear window, if it lights up (assuming the bulbs are good, no one ever changes them), then the problem is most likely in the turn signal switch, hope this helps!

The headlights lights are working but the brake lights aren't. I suspect a bad fuse but don't have an owners manual, so I need a fuse panel diagram for a 1996 Chevy C1500. Got one?


no, sorry . but i do have a suggestion that might help. do the taillights work? if so check the brake light switch on the brake pedal. also , does the high mount light work and not the rear ones? if so you may want to check the turn signal switch to make sure there is voltage on that circuit.

Fthe tail light works but the brake light doesn't work, it probably is the module that has a circuit board. I have replaced it 2 or 3 times on my 2004 XL Envoy ... can I get a part number and location...


First let's determine which brake lights are not working. Does the high mounted brake light work? Do both left and right brake light not work? If none of the brake light work, the problem could be the brake light switch at the brake pedal OR fuse #12 in the underhood fuse panel.
If only the bake lights at the corner lamp assembly don't work, check fuse #34 in the rear fuse panel.
The module your are referring to is the circuit board located in each of the corner lamp assemblies, check on website www.compnine.com for the part number of this item. I don't believe this is your problem though.

Brake Lights are not working.


check the switch itself,on the pedal,most likly if you drive this model car too long with a bad brake switch,it WILL damage the transmission!!

No taillights, brake lights or turn signals


This is usually caused by a defective multifunction switch, see it quite allot, the clue is the 3rd brake light, it is on a separate fuse and does not run through the multifunction switch on the steering column.
