      The alternator generates direct current for recharging the battery
      and for powering vehicle electrical loads.
      A 12 volts devices such as a starter solenoid or a starter relay may shorted and are the common cause to make the alternator failed to operate. The squealing noise is from the diode rectifiers in the alternator.

      Is the alternator belt new and is it being held tight at all times by the auto-tensioner. VERIFY that you do not simply have a belt with a very glazed surface caused by slipping or excessive wear. remember, an alternator when it engages places a very heavy load on a drive belt that turns it. Do not assume that the cause MUST be in the alternator circuit.

      I'm not sure everyones on the same page.Dorinda, unhook negative battery terminal clamp and srt aside. Hook up the best you know how the alternator wiring, should be a harness plastic multi-wire connector, a black ground wire ussually near bottom of alternator and a red wire positive connector near top side of alternator. The red,positive one must have an insulating rubber or black plastic piece aficst to stud of alternator that cannot be shorted to ground. Then hook up battery clamp. If you h

      have a voltmeter/ohmmeter, with before connecting battery back up check to see if you have continuity between the positve alternator stud threaded post and the metal case of the alternator, There shouldn't be any, Meter should read high as in infiate resistance, if not you have a ground short in this circuit. Some meters beep in Ohms mode, there should not be a beep.

      ok Bill, I will try what you said and see if that works. I've got to work the next few days but as soon as i get a free day I will try what you said and let you know how that went.I really do want to thank you for your advise

    How to replace cabin air filter?
    Location of cabin air filter in 1998 mercury villager?
      Safety Tip:
      Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes.
      Refer to your owner's manual for the specific location of your cabin air filter. Some are found in the engine compartment and others are located in the interior of your car, under the dash. Note that some models may have more than one cabin air filter, so be sure to check both and replace them when needed. We suggest replacing them in pairs to eliminate the hassle of future occurrences.
      Loosen the box and inspect the cabin air filter for debris, dirt, leaves and other objects that are obstructing the path of air entering the cabin.
      Remove your old filter, clean the filter box and install a new filter. Secure the box.
      Run the A/C systems with the doors closed to verify the repairs.

      As basic check the fuse if blown. Replace it and trace the wiring for grounded wire by performing a continuity test.

      Unfortunately no, they have a different connection. Well if you are willing to re-wire, then it will work. The problem is yours belongs to the 3rd gen and the one that you want belongs to the 4th gen of grand marquis'/

    Fuel gage drops to empty, what could this be
    fuel gage works on and off
    • Nissan Technical Advisor
      Either the fuel sending unit within the tank is weak or the gauge is defective. First thing to do is to check electrical connector and fuse if loose, if ok, remove and replace fuel sending unit.

    Where is the EGR located?
      Jack up the passengers side of the car, get a 1 1/16" wrench break loose the fitting to the manifold, hold a 24 mm wrench on the fitting to the manifold, loosen the flare nut on the tube. Then using a 10 mm socket, about 2 inches long, loosen the two nuts under the EGR valve, then take the both out, remove the vacuum hose to the top of the EGR valve, and the sensing line from the small tube. then completely remove the flare nut from the orifice fitting on the manifold. BE CAREFUL with the tube, do not bend it or break it, you may find PB blaster useful the night before on a cold engine loosen these fittings. Once the EGR valve is out, remove the orifice out of the manifold, remove the tube from the EGR valve, again be careful, mark the tube to EGR position before pulling this off, because the top fitting to EGR needs tightened before you put it back in, it will make the lower fitting difficult if you do not line it up right, dry fitting from under the car is helpful, mark it, and then tighten the top. Clean out the tube, be careful not to bend the little tube, either inside or outside the larger tube, it sticks out inside. Clean the orifice, clean the manifold face carefully not to score it, check for blockage there too. Apply antisieze to the orifice, put it back in the manifold, then apply antisieze to the bolts for the egr valve, and the flare nuts both ends. Apply some silicon to the egr valve face, just enough to hold the gasket in place, put the new gasket on, start the bolts two turns in the gasket, it will hold them in place, then start them in the manifold, then start the lower flare fitting to orifice, tighten the top bolts, and then the flare nut, connect the vacuum line, connect the sensing line.

    After dark, when my headlights come, my left blinker doesnt work but has a shortage sound and when my brights are on nei
    brights are on neither blinker works
    • CVO

      Inspect the flasher relay for any corroded pins, the headlights may draw so much current and the flasher didn't have enough current to operate the blinkers. For more info, navigate to via this link for wiring diagrams.
