no dashlights
hello everyone, I am totally fustrated with my 79 corvette....I have no dashlights..A fellow forum member sent me a fuse box pic, which i thought would be easy to find the location of the fuse. I located the fuse location, but it seems like their is only one connection inside....can anyone help me here......i have been thinking of removing the fuse box..maybe the connector got loose.....please help

My 79 keeps blowing the fuse. I put new swicth in mine, but it didnt' seem to help. I will pull the cluster back out again and look again a the printed circuit board. I'm thinking maybe there is a problem there.

could be that all are bad after almost 30 years.
having just done my 78s bulbs i can tell you that on the center pod
all but one of the lights was bad and the speedo/tach cluster itself
all but 3 were bad plus the circuit board was shot to boot.
swapped out the circuit board (new one on eBay for $39 shipped)and all the bulbs i have plenty of light now

I had the same problem with my 69. I checked the fuses and they were all good. It ended up being the head lamp switch. There is a rheostat in there for dimming the dash lights and after years of use they just go bad. Something to look at if the fuses are good. The other thing to check is make sure all the bulbs are good, over the year they burn out one by one.

make sure that there is not a loose hot wire behind that dash come loose. went through the same thing with a friends 69. changed the headlamp switch (had a burnt spot in the rheostat) but ended up a grey hot wire came loose and was grounding out and blowing the fuses. printed circuit board can come loose and stop making good contact too.

One of the things my vette mechanic suggested was to take an emory board to all the contacts on the bulb holders and traces. They corode after a while, and they where not the most sound connection to begin with. That and a little contact cleaner got my last couple of bulbs working.
If all the bulbs are out though I would definately go with the switch though. It solved the vast majority of my problems.
