Front right signal flashes very fast. I have changed the bulb and it worked for a few days, then started flashing fast again. Changed the bulb again, but fast flashing persists.

Does the rear blinker for the right-side work? If not, this will be the problem, if it does work, I would check the rear bulb as well because the resistance might be off causing the fast blinking, here is a guide to help as well:

If it still blinks fast with both new bulb, I would swap out the turn signal flasher. Check out the images (below). Please let us know what happens.

The rear blinker flashes fast. Front not at all. Both bulbs are good. I don't know the names of parts, but wiggled connection between the bulb mount and what it was connected to, and it started to blink normally, then quit. So disconnected at that point, put back together, and now it's working! Thanks for the help!
