not sure what causes it, but sometimes my signals will just not work. with lever still in position to activate signal, push button for hazards. then put signal lever in "off" position. turn off hazards. signals should work. temporarily anyway.
Have vehicle scanned to see if any codes are stored to determine the problem
The problem could be in you flasher located on the fuse block . or the multifunction switch located on the steering column.
Probably the signal flasher relay, but be sure all the bulbs are okay.
My sons 93 royal 88 Oldsmobile right directional would not blink. We changed the bulb and it started to flash.. hope that helps
I got it. It was the relay switch.
1999 Audi a6 quattro, How I fix the problem when the turn signals don't blink, but hazard lights work well?
A blinking "check engine" light is an indication that the computer has detected a SERIOUS problem that can result in permanent damage to the engine. You need to connect a diagnostic code scanner to find out what the computer has detected.
When both of the turn signals (indicators) of a car blink simultaneously, it is usually because the hazard lights are turned on.
If both your left and right trailer signals blink at the same time there is something wrong with your wiring harness.
Probably needs a fuse.
The flasher relay is defective. Replace it.
