When I put the turn signal on for either side, only the corner light comes on but not the flashers in the front or back nor do I have the green arrows on the dash. It seemed like the problem happened gradually as I noticed that before they wen't completely dead they would skip a few flashes or get stuck...very weird. My hazards work perfectly though. It's a 1994 Eldorado. Any help would be greatly appreciated...before someone rear ends me! Thanks!

 

check for corrosion at the bulb sockets or with grounds at each lite. Is signal flasher ok.

 

Both sides aren't working
