Elec. Questions
-My turn signals suddenly stopped working yesterday.
I don't believe there is a dedicated fuse for this. I don't know how to track the problem down.
-The dash lights don't work and didn't since I picked the car up (last week). Again, I don't know what steps to take. The headlights, highbeams, and tailights work fine.
-When I checked the fuses the bottom fuse in the box (there are only 5 or six) which is a 3 amp was blown. I think it said AC. I replaced it and it immediately blew again. Since the car doesn't have AC I'm not sure what this fuse is for.

your profile does not tell me what kind of car you are having trouble with - nor does the post
on a Sting Ray, the brake switch powers the turnsignal switch and the brake fuse handles problems

The brake switch meaning the switch that turns the brake light on when the hand brake is engaged? Because the brake light works.

no - the switch activated by the brake pedal to power the rear bulbs passes power through the turn signal switch so that one side can be interrupted to flash the rear stop turn bulb filament on that side and to include the front signal lamp

Can't figure out the dash lights either.

I provided some quick thoughts (as did Jeff) on your headlight, wiper and passenger door problems in the thread we hijacked a day or so ago. Here is a wiring diagram that may help you but you should invest in the Dr. Rebuild color schematics for your car.
Its critical to know if your brake lights work. If your BRAKE lights work (they use the same filaments as the turn signals) then the bulbs and grounds are good. The problem has to be where they are getting their power for their OTHER purpose from..e.g. TURN SIGNAL indicators.
If you don't already have a battery disconnect you should get one immediately and disconnect the battery when the car is not in use until you gain more confidence in your electrical system and wiring harness (and carry a fire extinguisher). Seemingly small electrical problems on these cars can turn into disasters unless precautions are taken.

Sorry, you did. I didn't understand.
The brake lights don't work.
Which fuse is for the brake lights? I know the bottom fuse in the box, the 3Amp marked "AC" is blown. I replaced it and it blew again. Is that the fuse?
And that's not the same as the dash lights fuse since the dash lights never worked and the signals did.

OK. I just checked again.
The brake lights don't work. I found a fuse that was labeled (below it) "Brake". The fuse was good but I replaced it anyway and they still don't work.
So it's probably a short in the signal switch itself. When the steering gears were rebuilt thay had the steering column off and maybe there was a loose wire that worked until a couple of days ago. But a short should cause the fuse to blow. I don't know.

if not, replace the brake switch

I just called the Corvette shop.
Since the signal lever goes up and locks into position (right turn position) and goes half way down and does not lock (left turn position) he feels that the problem may be in the turn signal mechanism. He said that it's not uncommon and wants to check it out and pull the wheel if necessary. It's about an hour away so I'll drop it of by is house which is 20 min away on Monday night. I'll have to be careful this weekend because I still plan to drive it!
Thanks for everyone's help.

the bottom fuse is for the instrument lamps, and since it gets power from the light switch, the light switch is supplying power or the fuse wouldn't blow. There must be a short to ground in one of the dash lamp lines (all gray wires) or sockets.
The flasher gets power on a pink wire from the key switch. Does the flasher make noise when the key is on and the signal lever is engaged?
stop lamp switch is powered by an orange wire from the top fuse. If the fuse is good check both sides of the switch with the brake pedal depressed. If both sides of the brake pedal switch have 12volts, the turn signal switch is probably the culprit UNLESS both stop/turn lamp filaments are burned out - unlikely - since the front turn lamps should at least come on, even if both rear bulbs are out. But worth checking, since it's been known to happen.

The only problem is driving this weekend. Shouldn't be too much of a problem.
