No brake lights or hazard lights?

Also is there a fuse for the brake lights? hazards? could it be the other sensor that is bad? any help would be great

Re: No brake lights or hazard lights?
The switch that is broken is for cancelling the cruise control when you touch the brakes. The other switch should have an orange and a light blue wire. The orange wire should be hot all the time, you can check that. You can also inject 12V into the light blue wire and the lights should come on. First though, check the STOP/HAZ fuse in the bottom right corner of the fuse box.

Check the fuse box. This happened to me the other day. My hazards and brake lights and turnsignals stopped working. The fuse, STOP/HAZ was simply blown.

Re: No brake lights or hazard lights?
checked all my fuses replaced one that was for courtesy lights just never thought to check for a missing one that is the only missing one though. Next i assumed the switch since it was broke(the cruise one not knowing thats what it was for) and then i was about to chase the ground wires

Re: No brake lights or hazard lights?
Hey all,
So I am having a similar problem....my brake lights dont come on on my 88 GTA. However, the hazards do & I checked the fuse and it is fine. Tail lights come on just fine as well when on.
Thoughts on this one?

Re: No brake lights or hazard lights?
It has three wires:
- orange - constant power
- light blue - for brake lights - goes into the steering column multifunction switch
- light blue/black - for the 3rd brake light
You should find power on the orange wire. And you should find power on the light blue wires with the brake pedal slightly depressed.
Let us know what you find.

Check the brake pedal switch. It is attached to the pedal assembly.

In the worst case, you can always get one from a salvage yard. Or you can check fleaBay.

Re: No brake lights or hazard lights?
If the lever won't even budge, it might be either broken or preloaded from the switch rod that runs along the column and actuates the actual switch under the dash (bolted to the side of the column). The rod might have popped out of its groove or something, that's always a possibility.
I would recommend trying to gain access to the switch itself and loosening it to see whether that will free the rod and stalk. If the rod is free but the stalk still doesn't move, I would recommend pulling the steering wheel off to investigate the multi-function switch.
Here's an article on adjusting the hi/lo beam switch with pictures: http://www.austinthirdgen.org/index.php?pid=16
