    Why won't my car go into gear?
    After I washed my car at an automatic car wash it would not go into gear. It was very cold out and thought maybe somehting froze under the car or a sensor. I opened the panel as instructed in the owners manual and was able to manually shift but now need to fix it. ...

      Possibly a frozen neutral safety switch / range selector on the transmission - perhaps some moisture has entered to cause the problem?
      When you state the car will not go into gear - does this mean you cannot manually shift out of Park, or into any other gear position - or does this mean the transmission does not shift automatically in Drive for the different speeds?

      Check your transmission fluid level, hopefully it is low bc thats the cheapest fix. Or the torque converter maybe going out I would try putting Lucas non-slip In the transmission. Works pretty good

      You could possibly have a broken transmission or engine mount.

      If this vehicle a shift control cable or linkage, It would be connected from throttle linkage to
      transmission. It's possible it could be defective.

      the service bulletin sounds like what john deere call a pip or product improvement. they probably get a kit of wires or something that they can throw on every car with in a certain serial number. we get allot of them on new models.

    The blower for the heating and air stopped working about 3 months ago. Then, worked for a month and now nothing. What?
    248,000 miles. Fuses seem to be good. The radiator does have a leak that needs repairing. Any ideas?

      The blower motor is located under the cowl by the wipers. Remove the cowl to access the blower motor. At the connector there should be battery voltage and a ground with the blower switch turned on with the car running or at least the key in the on position. Behind the blower motor there is a blower control unit which sends varying amperage to the motor. It is likely that either the blower or the controller is junk. Diagnose this using a 12 volts test light to determine if the motor itself is receiving both the voltage signal and a ground, and if it is and the motor is not running then the motor is junk. You can check for battery voltage into the blower controller from the fuse box and out of the controller to the motor.

    What is the alternative of the differential gear with a ratio number 3.92 of Mercedes Benz
    I could not found the Differential Gear Ratio 3.92 of my car. So I'm looking for an alternative. actually my car is E-200 STATE 1995

      Your best bet is check out the assembly with your Mercedes dealer. They may be able to tell you what vehicles your differential assembly was fitted to. If you are not intending to buy new, then a list of vehicles it was fitted to will enable you to carry out a broader search for vehicles from used or salvage vehicle sources.

    Why does my car hesitate when I step on the gas after a full stop, after a long drive, it will go to around 40 miles max
    rpm gets loud up to 4000, but if I turn off engine then restart again car will start running normally

      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. 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.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

    4 bolts fell out of what seems to be the gear box in rear, in front of gas tank. It goes into reverse, but no forward.
    3 bolts are missing and the 4th is broken. I just got this car a few weeks ago, but it has been well maintained. The manual in the car does not show nor discuss: gear box; differential; transmission or any reference to steering.
