Try replacing the headlight switch. Do the front parklights work and not the rear ones? If so check the harness to the rear of the vehicle for breakage.
Check bulbs could be bad switch in steering column
check if reverse lights are working, if not replace the reverse switch plug located underside near the gear box, centre of car, there are two plugs, check if wires are frayed, this happened to me and when I replaced this my turn signals started working. hope this helps
Most vehicles have two flasher units. One for the turn signals and one for the hazards. If you have already replaced one try looking for the other one. Or check for a bad trunsignal switch
u have two flashers on your car... one for blinkers and one for flashers.
vacuum tubes
It should be the fuse, in the fuse box at the Driver Side, check for the number 10 Fuse (7.5 Amp) it might be blown
Most obvious thing to check would be the flasher relay located under the bonnet
It contains two relays, one for hazard lights and the other for turn signals. The one for the turn signals is defective and must be replaced.
check you light bulbs
let the wife reverse park in to a small space
Turn signals just quit working- have replaced flasher- checked all bulbs and fuses, checked all obvious wires, cleaned grounds, replaced the turn signal switch (that was an adventure). At a loss- any help out there? Hazards work fine- all other lights work fine- turn signals dead
Check fuse Check bulbs--they are double filamented with the smaller for turn signals Replace turn signal flasher--Most common problem
