hi, im a new vette owner. I just purchased my vette a 75 stingray, and im trying to get it ready for state inspection. The left turn signal does not work when i turn it on the back light stays on and the front side marker does not come on at all, i changed the bulb and the flasher, any suggestions? Also the horn does not work, i changed out the horn relay and i have read some of the other forums and they said to run a positive and negative from battery directly to the horn when i did this it worked for a second and then nothing else, i went to my local auto store and bought an aftermarket horn and it still did not work im new with these cars so any help would be greatly appreciated.
