As as rule... No.
Usually automobile turn-signal circuits separate left and right sides (not rear and front).
Assuming the bulb is OK and the correct one (double filament?) your most likely culprit is going to be the socket on the one that does not work or it's wiring connection.
Depending on the design, the hazard-switch could be at issue too as these devices switch the wiring loom connections around when the engage or disengage.
Good luck.
A defective brake light switch could cause the problem. Also a defective turn signal switch could also. The brake lights work through the turn signals. It cancels the brake light so that the turn signal can work.
The turn signal switch is probably a bit loose, so the bumps are jostling it enough for it to switch on.
No. The horn and the turn signals are on completely different fuses and wiring. I don't know why you thought that the horn could be made to stay on by the turn signal, but that's your answer. ========== The turn signal switch and it's plastic housing could pinch the horn wire against the steering column and cause the horn to sound. You would probably hear a change when you wiggle or click the turn signal switch. This can happen because many horn relays are activated by grounding the wire inside the steering column, so if the insulation is damaged it can easily be made to sound.
Check the connector pins on the housing that contains the signal switch and the headlight switches that connect to the signal light switch these pens are famous for coming loose fron the circuit board thy are soldered to. had to replace my switch housing.
Because the hazard/turn signal relay has failed. A defective/intermittent turn signal switch can also cause this symptom.
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.
If the turn signal is working it's either the brake light switch or the turn signal switch.
it is most likely a fuse or at worst the turn signals and stop lights work through the turnsignal switch
Yes. The relay that controls the turn signals is built in the switch.
Try checking the turn signal flasher. Not to be confused with the hazard flasher.
What you describe could be caused by the Hazard Light switch being turned on. When you observe this symptom, get out and check to see if the parking lights are flashing. If they are, then find the Hazard Light switch and turn it off.
Perhaps it is the wiring or a fuse that has broken.
