Yes, many erratic electrical problems with the Ford Taurus can be caused by either a weak battery or a bad Transmission Range Sensor. Even though a weak battery can start your car, it causes the computer to think there is a problem and start shutting off accessories, even though the voltage returns to normal once the engine is running.
The battery is the easiest to check (with a $10 voltmeter from any auto store) and cheapest to replace, so start there. With the engine off, the battery should measure about 11.5V to 12.5V. While cranking the engine, the battery voltage will drop to 10.0V to 11.0V (you'll need a helper for that check). If your values are lower, replace the battery. The 56R battery is the basic Taurus battery, and the optional 36R has more cold-start and reserve power, for about $15 more. Check your owner's manual, as some years or models might be different.
NOTE: The battery may be low because the alternator isn't working right. Check the alternator for proper output. Put a volt meter across the battery with the engine running. The alternator should keep the voltage somewhere between 13.5V to 14.5V. If it's much below that you probably need a new alternator.
If that doesn't fix your problem (especially if your radio shuts off when you put the car in reverse), have a transmission shop replace your Transmission Range Sensor. That should cost about $150 total.
Usually a bad flasher or problem in steering column
Bulbs? Sockets? Steering column switch?
Sounds like an electrical problem, check your battery, alternator, and fuse box, and light wiring.
*you might have a problem in the steering column *you may need to replace the flasher fuse in your fuse box.
Could be turn signal flasher Check bulbs Could be a problem in steering column
Bad flasher? Switch? Bulbs? you may also have a short in your steering column, i had a similar problem and after merely adjusting the steering wheel height and playing around with the blinker they started working again, good luck
For safety reasons, you should fix the problem so that you blinkers work correctly. This is a fairly common problem and the cost to repair will likely be minimal. For inspection purposes, however, your blinkers only need to work correctly during the inspection.
Replace the flasher relay. If that does not correct the problem you have loose wiring.
First clean battery connections, if this does not correct problem the battery needs replacing.
i had the same problem...turned out the hazard flashers button on top of steering column was in the wrong position ! ...talk about simplr..hope it works for you
On the Jetta, the dashboard warning light with a circle and a box above it is indicating that there is a problem with the battery. This light also indicates a burned out bulb in the headlamps, taillights, or blinkers.
No, my steering is fine.
