    Why headlights flash on and off while driving.
    Headlights flash real fast on and off while driving then go off for a few minutes, then come back on. It has 74,000 miles and runs real good except for this problem.

      A bad regulator inside the alternator is the cause of this problem, local auto parts stores can't detect it. A new alternator will fix it.

    Why headlights flash on and off?
    When using headlights sometimes they flash real fast on and off for a few minutes then go off altogether. Then after while they come back on. Dash lights do the same when lights are flashing on and off.

    What is wrong, 4 times yesterday my Sable stopped, just like someone turned the switch off.
    This is the first time this has happened. Nothing worked. It was like the battery had been disconnected. The radio even switched from FM to AM. I tried the four-way flasher, and that didn't work either.

      I would remove and clean the battery terminals. This is not that uncommon on these vehicles.
      Then try jump starting your car. Let me know how you make out.

    Replace 13350 (SF-588) Flasher
    I have a 1995 Mercury Sable 3.8L V6. I removed the panel below the steering column. I think the flasher is located above and to the left of the fuse panel. It's a small black cube with part #13350A2A (Made in United Kingdom). If my evaluation is correct, how can ...

    K-K-K - 2000 Mercury Mountaineer - Preventive Maintenance - 10/11/2014
    After a 10 day vacation, my mercury will not start. I have spark but no gas. I think it may be the fuel pump.
    Is there a way to get to the fuel pump without taking the tank off??? Or is there a way to possibly jar the fuel to get pump started. Or is there dirt/debris in the fuel pump possibly?

      First check the trunk for a fuel shutoff. Usually on fuel tank side. When you first turn on key you should hear a short humming sound from the tank

    How do you turn the check engine light off.
    put a new fuel pump & fuel filter on after having it put on a diagnostic computer. it said I had low psi on fuel system. I unhooked the battery & it went of but came back on after 12 miles.

      The check engine light is located on the dash and stays on if the computerized engine control system detects an engine performance or emissions problem.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA, etc. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light. There are literally hundreds of possible fault codes and therefore numerous reasons for the MIL condition.

      This step is important - retrieving the stored fault code and relaying this detail - will provide good information to assist in diagnosing and repairing the issue you are having.

      Check engine light will come on if seal on gas cap is not working properly. Get a new gas cap and be sure to tighten until it click about 3 times whenever you put in gasoline.

      Avoid throwing money or any parts (such as a gas cap) at the problem - without first scanning the OBD system and fault codes.

    What is wrong with my car?
    Recently, my car started making a humming noise. It gets really loud at certain speeds. I've looked into it, but my cars symptoms aren't exactly what everyone else's seems to be. It starts a low humming noise at 20-30, immediately goes away at 30 mph. Then again, ...

      First question, is the noise localized - that is; to one side or or one specific wheel? If yes, then suspect that location wheel bearing - or hub assembly.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the rear axle hub bearing assembly from around $24.00 each for your vehicle. Be sure to replace both sides (left and right) at the same time due to mileage / age / wear considerations. Keep in mind, these are only the parts prices - the labor to install will be additional cost. Check the 'How-To-Guides' feature on the Auto MD website for the specific steps to install.

    Why doesn't my seats, locks, trunk, and fuel door not work?

      For the driver power seat, did you check for voltage at fuse 7--20 amp, underhood fuse block. Use a testlite to check for voltage at the fuse circuit, hot all the time.

      Check the wiring harness that goes into the driver door on the hinge side. For the driver side power seat, the black wire with white tracer is voltage. Black wire ground, check them both. Make sure wires aren't broken, because the driver is open and closed a bunch.

      You will need to pull the trim panel and check for battery voltage and ground at the motor connector while activating the switch.
