1977 GMC crew cab 3/4 ton V8 turn signal problem.

Symptoms: 1. Head lights off. left and right turn signals work. Hazard warning lights work. 2. Head lights on. All lights are on. right turn indicator on the dash board is on. left turn signal works. Right turn signal does not work. Hazard lights do not work. How can the turn signals work with head lights off, and only work for left turn with the headlights on? The headlights should be a separate circuit from the turn and flasher circuits. Head light switch turns on marker lights, parking lights and tail lights correctly. Left turn and right turn switch is the same for head lights on or off. What would keep the right turn from flashing with the headlights on? What would keep the Hazard lights from flashing with the head lights on? Why me?

SOURCE: electrical problem

Find the ground wire on one of the lights and add another ground wire to a good clean metal surface and see if that fixes the problem. It defently sounds like a ground problem at one of the lights.

2004 Chevy Silverado Extended cab. Why did my blinkers / hazards, interior lights, instrument cluster lights and driver window stop working?

These vehicles were known for faulty hazard switches. They would cause an intermittent turn signal flash when you hadn't activated turn signals or they would prevent the turn signals from working at all. Operate the hazard switch and see if the turn signals work again. If so, replace the hazard switch

2005 Impala, directional signals inoperative. Flashers are working. Replaced the hazard warning switch. Still no directional signals, hazards work. Now, car will not start.Buzzing sound from hazard sw

There is a good possibility that the hazard warning and directional signal lights have nothing to do with the starting or operation of the engine. There are many things that might cause the car to fail to start. The battery must be fully charged, and in good working condition. No corrosion on the terminals. good solid connections. When you turn the key the starter motor should turn the engine over. If that works the carburetor will need gas. If you have gas and spark, the engine should run. Hope that helps.
Turn signals work with the tail lights and parking lights on the front. You should turn on the Head lights and check to see if the tail lights and parking lights come on. You will also want to check to see if the flasher is plugged in. All the light bulbs must be plugged in and working to operate the flasher for the turn signals. good luck

No left turn single

assuming you have check both front and rear signal lights and they are working then it sounds like the signal flasher is not working for the left side only.put on the hazard flashers to check bulb operation and if the bulbs work then the only thing in the system is the turn signal flasher not working for the left side.the signal flasher looks the same as the hazards but is a different flasher located in the same area as the hazard.

I have a 2006 F350. When my right turn signal is turned on, it flashes rapidly, faster than the left. Could you please advise me to what the problem may be? Is this serious? Thank-you Brent...

one of your turn signal light bulbs is burnt out. Turn on your hazard lights and walk around the truck to identify the burnt out bulb that will need to be replaced.
