Have the car listed above everything works fine but the turn signals when it rains my signals start glitch on me. It will work here and there and sometimes even when it is not raining but mainly raining is when it is the worst. I looked at both lens and front and back and I don't see any leaks. Just need a couple of problem fix ideas anything helps.

Welcome to 2CarPros.

When you say glitch, what exactly happens? Does nothing turn on? Do they turn on and not flash? Do the flash really fast?

Let me know.

Basically when the dash turn light is suppose to work it stops and the comes back like someone playing with a light switch if you get my meaning. I don't know if it is the fuse but that wouldn't make sense when the rain effects the car and the lights do not blink fast if wondering I put new bulbs in.

Welcome back:

That sounds like a grounding issue. If it was a fuse, it wouldn't come back on. I attached two pics. They are small portions of a wiring schematic which show where the signals ground. They will be on the left and right side of the trunk. I need you to check them to make sure they are tight and not corroded or damaged. They are the black wires in the pictures.

Also, let me know if this happens if you turn the hazard flashers on.

Let me know what you find.
