Default Now im really confused

Started out with a blown fuse, everytime I push in hazard button on my 86 corvette the fuse would blow, I traced wire diden't find anything, so I said no big deal I wont use my hazards. Well now when I push brake pedal I have no back-up or break lights! Looks like im going to have to take it in and get checked out, I can imagine what that is going to cost me !! Does anyone know what else I should check before I get raked over the coals on a repaire job?

Get under the driver's hush panel and check the adjustment of the brake light switch mounted on the brake pedal. It's slides back and forth for adjustment. Have someone look at the break lights while you adjust it back or forth. There are two down there. I believe it's the one that does not have the rubber vaccum hose going to it.

Default checked switch

I checked the brake pedal switch had wify look at brake lights, the white plunger clicks then fuse blows almost right away, if brake switch is bad would it blow the fuse? Also I have 2 switches on the brake pedal they are white one of them has 2 connectors on it but it is not pluged in.

The switch on the brake pedal with the vacuum hoses on it is your cruise control.

Cruise/TCC on automatics.

The circuit you are having problems with is a very simple circuit. Look on pages 8A-11-5 and 8A-110-0 of your shop manual.

Default thx

Thx, I checked the pages looks like the hazard flasher is tied into brake switch. I changed the hazar flasher so it looks like I might have a short
on the wire going from the hazard flasher to the brake switch.

A good way to check that is to unplug the componets on both ends and leave the wire in question fee. Then test the wire to ground with your ohm meter. There should be no continuity to ground with everything unplugged from it. If there is, then you have a short to ground somewere along the wire that is not supposed to be there which has to be causing your fuse to keep blowing. Then it's just a matter of tracing the wire within the car. It's all about using the shop manual diagrams as a map to test and eliminate sections and components of the circuit at a time, and narrow it down to where the problem has to be.

Yep, it's just a short. The time consuming part will be finding it. Just take your time, have patience and you'll locate it.

Check all your bulbs. Perhaps one of your taillights is broken and shorting out. This is used for brakes and hazards.

Through personal experience I suggest your problem is a short in the wire inside your steering column. The wire chafes in there. It is the hazard and brake light circuit sharing one wire. It's abraided by the tilt.

About $300. The piece of electrical tape wil be about $14 (shop supplies)
