You can check the battery, but I don't believe that it's the battery. Check the "multi-function switch" You will have to remove the plastics around your steering column. Then, on the bottom side, there is a big black box, attached to your windshield wiper/cruise control lever, held in place with, if I remember right, three bolts. Take those loose, and trace down the wires. They should run under the dash to the left side. There should be one bolt holding the clips together as well as the plastic snaps. You can't miss it. It's probably two inches across and about a half inch wide with probably thirty-five wires. Unplug it, and pull it through the dash and column. Install the new one. Now, you would probably be safest if you unhook your battery before you did all this. Just a precaution. And be prepared to shell out a couple hundred for the part. It's not cheap as it controls your brake lights, turn signals, hazards, windshield wipers, and cruise control. I believe that it runs 180 at Autozone. Good luck, and I hope that I'm not too late in answering this for you.
A burnt out signal bulb, a faulty blinker relay, a faulty blinker switch, a loose connection or a broken wire are all things that can cause the turn signals not to operate properly.
Yes. The relay that controls the turn signals is built in the switch.
Nonfunctional Brake LightsOne possible cause of this issue is that the brake light switch is not adjusted properly, or the switch could be defective.
It is your multifunction switch that has gone out. It is located in the steering column. I used my emergency lights and it blew out brake lights, turn signals, and emergency lights. In newer models Chevy did a recall not so for our older models. Mine is a 1995.
I would check the blinker bulbs on the side that doesn't blink (front & back). If neither side is working,there is a round chrome blinker fuse,located under the dash board close to the fuse box,it's width is about the size of a half dollar. If that doesn't solve your problem,then it most likely will be either in the wiring or the switch. If it is in wiring or switch,I advise you to take it to a mechanic,you do not want to mess with the wiring or switch,you could cause yourself a big headache and pay A LOT more...
Have a mechanic find the cause and fix them, or do a bit more of an in-depth diagnosis and give a description of the problem if you want help doing it yourself?
on my truck on the top of the steering while caseing theres a little black switch if that's flipped just alittle bit it will cause the turn signals to not work try flipping the switch both ways and try the turn signals and see if that works
NO.. It will not.
Is your headlight switch and blinker switch the same? If so, this is called the combination switch. Sounds like it is bad and needs to be replaced. Not uncommon for these to break.
Be sure the dome light switch is not turned on manually.
Next check the turn signal switch inside the steering column. check to see if the bulb is dead
A bad ground wire is the most common cause of turn signals and brake lights not working. The ground wire connection might be corroded.
