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
A speaker is like a microphone in reverse. Instead of converting sound into electrical signals like a microphone does, a speaker converts electrical signals into sound waves that can be heard.
Most obvious thing to check would be the flasher relay located under the bonnet
let the wife reverse park in to a small space
check you light bulbs
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.
It might be that one of the dual filament light bulbs in the system have had the 2 filaments short out with each other. Usually this also causes problems with the stop signals,and turn signals also. I had this happen on a car a long time ago,after I had already replaced the switch. Always check the bulbs first.
