the flasher is located underneath the driver's side of the dash, next to the steering column:
this is most likely a faulty multifunction switch which is a common failure, which the turn signal switch is part of. Below are both test procedure and then replacement directions:
the signal flasher will be located in a small relay box that holds one other relay, so have them look for 2 relays together in same box.
possible bad ground going from the turn signal flasher or short in wiring harness. below is wiring schematic so you can trace and test wiring for shorts:
Same part number
didnt clarify enough. same part number as it is the same flasher. it controls both hazard and turn signals.
yes, it is very possible for the part of the relay that controls the hazards to be functioning while the part that controls the turn signal is faulty as they are different circuits inside the flasher itself
