most likely the turn signal flasher, located under the steering column to the right.
The front turn signal bulb is blown. This is a feature of all modern cars, so that the operator becomes aware that the bulb is not working.
Under a sliding cover on the plug body. Or: press the spades together to withdraw the plug from the body, sometimes fuses are hidden there. Or: one of the lamps is actually a fuse and is not a lamp.
I suspect your turn signal switch is bad. The power runs thru the switch and it can act up like this when they are bad. You will need to have a mechanic look at yours.
If you are referring to house wiring, then you don't normally connect lamps in series with each other; they are normally connected in parallel with each other. When lamps are connected in parallel, each lamp is subjected to the same voltage; providing this is the rated voltage of each lamp, them each will operate at their rated power.If you did connect lamps in parallel, the you would find that the lamps with the higher power ratings will be dimmer than the lamps with the lower power ratings -which is not what you might expect!
YOU ARE A LONER GET A LIFE
Check fuses
Blade Type ATO/ATC Automotive Fuses: 10A for the turn signal lamps & 15A for the Brake/Hazard Lamps. Hope that helps.
I would go with a new turn signal switch, all the lights run through it. It seems to be a problem child.
troubleshoot head lamps on 1988 grand marquis? Not working...fuses OK
Check the fuses.
I would check switch. My 92 would only come on when working the knob. I went to the junck yord and pulled one. Now it`s ok.
There is a recall notice to replace the sockets on the lamps for the stop and turn lights. However, every time I have taken mine in, the dealer has no parts in stock!
If just one tailight is the problem - run a wire from the functioning one to the non-working.
they're on different fuses....but i also suspect that it could be 2 different fuses are blown....check the ground connections to body to both lamps/lens bodies at rear
try replacing your bulbs and check sockets for corrosion or possible loose wires try wiggling the wires
Check, Fuses, Bulbs, Switch,
my Oldsmobile alero did the same thing. It turned out to be as simple as a blown bulb in my tail light.
