Of course thw owner says worked last summer. But the real quiestion is if it's a fuse, why hasn't he fixed it?
Look for other gems not working correctly.

True. Kind of an old guy and has come down on price. Has done a lot of updates. Engine and brakes. Don’t mind putting a little money in it. Just don’t want it to be big cost

Bring a new fuse to the car. As said above, anything else not working? Might also be something as simple as a ground, which these cars have known problems with. You are buying an old car that most likely has had lots of hands in it so you probably should anticipate big cost, sooner or later. I'm kind of AN OLD GUY too with a 78 I know these things.

Assume the worst....maybe hes being straight but if it was a fuse he woulda done it
Agree with bringing a fuse with you. I see tons of old cars that appear to be priced real well but they just arent selling (unless its fire sale price or you fall in love with it Id be picky) as the buying crowd is kinda smallish these days.
Seen the ads that say "Has ac just needs a charge"? another classic bs line.
The charge was lost because....(it costs a bunch to fix!)

i always try to budget a grand or two when buying any used car you just dont know.

I don’t think the widows and wipers are on the same fuse. If they are both blown you gotta ask why. That being said if it’s a good price and you want it............

@cuisinartvette beat me too it, but <sarcasm> I bet the A/C worked last summer, and just needs a recharge. </sarcasm>

Make sure you get buy in before you go see the car, but bring fuse(s), a multimeter, and a screwdriver. Make sure you can unbolt the kickpanels to look at the #2 body mounts, too.

Default So I bought it

You all win. I did kind of assume bigger problems. It’s not a fuse. The engine has be reworked. Lots of stuff so while messing with fuse box see all these wires unplugged. Want to do stuff on my own but don’t know where to start

Well, start with a wiring diagram.

http://wordpress.keystonestatecorvet...m/?page_id=118

And then order an owners manual, shop manual, and assembly manual.
All of the vendors carry them (be sure to get the GM version), even RockAuto. You can find OEM manuals on eBay, too.

I think that the flat connector goes into the key buzzer.

Congratulations on the car. Looks sharp!

Willcox Corvette offers a free .pdf download of the 1978 Corvette Electrical Troubleshooting Manual. This manual is 1978 Corvette specific not like the standard GM line diagrams you may find online.
LINK: https://drive.google.com/file/d/0B28...JrTURuMGs/view
Note, The flat connector Bikespace points out is on page 18 and is in fact for the buzzer. C122 is the connector. #14 Orange & #20 Lt. Grn as an example of how GM called out connectors.
And it looks as if your buzzer unit is missing, see the empty Long White connector on the right side of your fuse panel.

I will ask a leading question....

"Would someone selling a vehicle replace some simple fuses and/or relays to get everything working as it should, to maximize asking price; or would he/she just sell it as-is, at a significantly lower value, because they did not want to bother with it?"

Now, you decide if those non-working items are easy to fix...or not.
