Question about 1984 Cadillac Eldorado

1 Answer

Left rear blinker and break light stopped working 84 eldorado

My left blinker stopped blinking about 2 weeks ago, it still turned on just wouldn't flash so i had to click it on and off if i wanted to turn. now the same thing is still happening except it wont go on at all on the rear and the break light on the left stopped as well. its a 1984 Cadillac Eldorado. i think its a bad ground connection but i don't know how to go about fixing it and don't have the money to pay someone to do it. can someone please tell me how to repair it i cant afford a ticket. thanks.

See if you can locate a wiring diagram for your vehicle. I have a 92 Seville and the wiring for the brakes and blinkers runs through the turn signal switch. The switch generally goes bad just from everyday use. They lose connection and you get intermittent problems (much like yours). Consult a wiring diagram, if they do run through the switch then I would recommend replacing that. Start there. Cheers.

Where does the flasher go?

  • Lie on your back under the left dashboard and look up along the left side of the steering column. Illuminate the area with the flashlight to assist in locating the old turn signal flasher, which mounts on a metal bracket, just above and to the left of the steering column.
  • 4Grab the old flasher by hand and pull it off the bracket. Depending on the model of your Cadillac, you may need to push aside some wiring harnesses to grasp the flasher.
  • 5Plug the new turn signal flasher onto the bracket. Reinstall the lower dash covers, if you removed any in Step 2.
  • 6Place the key in the ignition. Turn the key to the "Run" position.
  • 7Activate the turn signals on the left side of the car and get out and inspect them to make sure both front and rear bulbs are blinking, as designed. Switch the turn signal lever to activate the right signals and visual inspect

    '96 cadillac eldorado left blinker blinks fast

    Have you checked to see if you have a blinker out? If you do, then thats your problem. If not, check your blinker fuses. Hope this helps, James Booth.

    Left blinker is fast front blinker light working left rear blinker light not working.

    When a turn signal bulb is blinking fast, it is an indicator that a bulb is bad in the system. Replace the left rear turn signal bulb, then see if the left front blinker has gone back to normal. This is most likely your problem. Let me know if it is still a problem and i will help you fix it. Good luck

    2002 turn signal relay.blinker r side bink fast

    The fast blinker is letting you know that your bulb is out. Once replaced, it will blink at it's regular pace again. This happened to me about a month ago and that's what the guy at the parts store explained to me. I put in a new bulb and everything is now back to normal. People were flipping me off and blowing horns at me for a couple of weeks every time I needed to turn left, well that's b/c my rear left signal light was blown out.
