Definetly check the flasher relay under the dash. Once you unplug the relay, pop the plastic cover off of it. You can do this with a flathead screwdriver. Inside is a circuit board. Check the soldered connections for cracks. If you find a crack, heat up that connection with a soldering iron. You don't even need more solder. Just heat up what's there. Easy fix. . t$ l: N& I2 x: O* ^- d5 g
