The first question I would ask is if you were running incandescent or LED lights. If you're running LEDs, and didn't install resistors - or the resistors aren't functioning properly, there's your problem. LEDs take a lot less energy to light up, so to dim the marker lights, the market light circuit needs to have additional resistance added in order for those LEDs to not be fully illuminated.. once they are, they can't get any brighter.
If you will notice the hazard lights are not actually flashing, reason being, the hazard flasher relay is defective. Replace it.
first thing to replace would be the flasher can
Probably Flasher
The flasher relay in the tow vehicle needs to be replaced with a heavy duty one.
Replace the turn signal flasher relay.
I have the same problem. any resolution
you have bulbs burnt out either on the front or rear of your car or your flasher is going bad
you lost ground to one of the light sockets or hqve a bad socket in one of the lights
the flashing lights are the fireflies or the beetles :)
If the turn signals on a car works but the hazard lights do not there may be a problem with the flasher switch. The flasher is located in the steering column, and a damaged unit can cause the lights to stop working.
flasher has gone bad and needs replacing.
lights flashing on an a/c control head usually indicate a pressure problem in the .c system. possibly low on freon
