Hey guys, I have a bit of a problem with my fuse box on a 72 cutlass with a 350. About a week ago the turn signals went out, so I went and immediately replaced the fuse, which was blown. Today, the fuse went out again, and after replacing with another brand new 20 amp fuse. However, now when I turn on the right hand signal the my oil gauge and interior lights blink, while the signal doesn't, yet the left hand turn signal works fine. Any ideas?

Sounds like you have a really bad ground on the right turn signals.

Isn't that supposed to be a 5 amp fuse? I had a similiar problem with blowing turn signal fuses on my 98. After the standard diagostics of the signal wires and taking the steering wheel apart to check those wires, connectors and switch showed nothing, I was frustrated as heck. I pulled the fusebox away from the wall as much as I could and looked behind with a mirror. I didn't see anything, but put a fuse in and it worked OK. I tightened the box back to the wall and the fuse blew. Obviously something behind the box was getting crimped causing a short. I loosened the box off the wall a bit and haven't had any problems since. Not the right way to fix something, but good enough....

I had the same issue its a bad ground or connection. In my case i found the problem it was a loose wire/ broken connector.

Sounds like a bad ground make sure to use correct fuse if it is rated to high you may find your problem the hard way. Crispy wire is no fun.

Yeah - check the usual stuff: grounds and socket contacts, and make the bulbs are all the right type and in the sockets the right way.

If all that stuff is good, think about whether you need to take a look at the signal switch or wiring.

well it took me long enough but I've finally traced the problem to the signal switch in the column, ordered a new one and hopefully will be good to go after that!
