Turn signals not working
I had a problem with my turn signals not cancelling. When I checked the turn signal switch it had broken allowing the cancel springs to move when the lobe on the hub turned. I tried epoxy gluing the springs in and took the car for a test drive. The turn signals wouldn't work at all and it turned out neither did the brake lights. Both fuses had blown.
I had some trouble getting the steering hub back on and it looks like I pinched a couple of wires against the housing getting it back on. I decided to replace the whole switch because the gluing thing didn't work. Once I got the new switch in and tested it the turn signals still didn't work. I'd replaced the fuses but the turn signal fuse had blown again. I noticed when I moved the turn signal lever there was a flash and a short circuit. The side of the switch was touching the housing. I added tape to the inside of the housing and replaced the fuse. Still won't work.
When I stand on the brakes the brake lights both work, but if I put the left turn signal on the left brake light goes out (doesn't flash). Same on other side. So I know the bulbs work. I replaced the flasher but still no turn signals. I tried the hazard switch too but nothing.
So I don't know what's wrong really. I unplugged the new switch and reconnected the old one and they still don't work. So I'm pretty sure it's not the switch. What am I missing?
Is the turn switch supposed to be earthed? Because the metal tabs are very close to the housing (or would be touching without the tape) are they in fact supposed to touch? I'm thinking no but now I don't know. This switch seems a slightly different shape to the previous one and is a slightly tighter fit.
So all the light bulbs work, the fuses are good, the flasher is new, and the switch seems to be doing something because when you select a left or right turn it makes the brake light go out on that side.
Also, the new switch included a hazard knob, which I didn't have before. How does the hazard switch work on a 67? I can see that it's spring loaded so you press it in to turn them on but how do you turn them off? Once it's pressed in you can't press it again. Does it turn off if you turn the wheel or something?
So any help appreciated. My turn signals used to work before, and I replaced the original switch about 6 months ago without any issues. This is doing my head in now. Why won't they work?
