Passenger blinker flashing rapidly

[Tbbroder]

I just noticed my passenger blinker is flashing faster than usual. Normally this would mean that a bulb blew but I checked all of them and none are bad. What else could it be?

You sure they are both flashing on the front?? I get this alot and one of the front lights will be out. Half of it will flash 90-to-nothing.

Both bulbs will flash but they aren't as bright as the drivers side.

So I decided to take both bulbs out of the front and Clean the terminals with a wire brush. I had already did this once but it worked this time. Thanks for the help guys.

Probably were not grounding good.

I've also had this issue end up being a cheap bulb with one filament going bad on the tails. Everything still worked, but once I replaced the cheapo bulbs that came in my tails with some Sylvanias the issue went away.

Is this the only ground for the rear harness?

Yup. its usually grounded to the frame or hitch.
