1. Note that if the switch is IN/ON (but the 4-way flashers aren't flashing cuz of the switch problem) and you move the indicator stalk to indicate a turn (and of course the blinker doesn't blink) it will tun OFF that brake light, so if one taps the brakes, it will look like one is indicating a turn in the opposite direction! Keeps the drivers around you confused - not necessarily a good thing.

2. I know from experience <sigh> that the 4-way flasher switch will run battery down if left in the IN/ON position.... WITHOUT the 4-way flashers flashing.

HELP!!! All at once I lost my brake lights, turn signals, hazard lights and cruise control on my '04 Vette. I haven't tried cycling the hazard switch yet, but would doing that effect my brake lights not working? Any ideas on a fix?

I have completely dissected a bad hazard switch and WOW!:eek: There very complex inside, There are 5-6 sliding switch contacts, an integrated circuit IC Chip some diodes and a bunch of small springs and some lighting circuits and bulbs.
I believe the contacts get tarnished and or loose some of their tension over time cause of heat and vibration. The contacts did look dirty. There would be NO way to easily repair that switch! :rolleyes:

If you still have your old switch, it's a VERY good donor for electrical test pins. The Male pins in the switch base can be removed (busted out of the plastic base) and used to test female pins in female connectors.

In a lot of C5 electrical gremlins the problem is cause buy poor contact in the electrical connectors. If you insert that male pin in a female pin,,,there should be a firm grip on the male pin. A very good example of where the female pins fail the most is in the wheel speed sensor connectors. When mine was bad, the male pin would literally fall out when the female connector was turned up side down.


Without testing the female pin tension,,,,you can end up chasing your tail and replacing a LOT of expensive parts.

Having trouble with your turn signals? Sometimes they work, sometimes they don't? Mine was doing that too, at first I could mess with the emergency flasher button and the turn signals would work. Then I had to move it more and more. Finally, they quit working all together. So I finally took the time to replace it. I documented the whole method here:

This is using the 'easy' method where you can do it through the radio hole.
