Driving home yesterday my brake lights were working fine until about a mile from home when they stopped working (my girlfriend was following me) Got home messed with a few things, but nothing. The 2 rear light bulbs light for my tail lights and blinkers, but not the brakes. Also the hazard lights work in the front but not the rear. Could this be my brake switch and if so can i obtain a new one at a local parts store?

The brake switch closes when the plunger comes all the out of the housing. The switch body is threaded making it adjustable. It’s possible that it is out of adjustment or doesn’t have power. Check things first before you start replacing items. I’d first measure both the orange and the white wires on the switch. Measure each one to a good ground. The orange will always have power while the white gets power when the pedal is pushed down. These are common switches and should be available from the auto parts store.

Could i need a new fusible link. I removed a rectangle shaped box about and inch and a half long from under the dash. It lead to an orange and a pink wire it has two prongs. it reads

I
m not sure what this is but it was near where the switch wires lead. I noticed that the hazard blinker only works when my brake switch (which are still not lighting) is either not plugged in or if the button is fully released. Also my blinkers arnt working but the flasher is definetly ok. [img]graemlins/clonk.gif[/img]

No fusible links under the dash. It's a safety thing because they get hot when they burn open.
