SOURCE: oil light blinks on and off could pressure switch

Oil Pressure Switch Operation:
00134_oil_pressure_switch_gauge.jpgInformation relay unit for the indicator light or gauge on instrument panel. It contains a diaphragm that responds to changes in oil pressure. When the oil level is over a pre-set limit, the diaphragm opens the switch, turning off the light. When level is below the pre-set limit, the dash light comes on. In later model cars, if the oil pressure drops, the switch turns off the fuel pump, to stop the engine and limit damage to internal parts. Oil pressure switches can be grouped into two categories, units for electrical gauges and for mechanical gauges.

Oil pressure can be checked at the sending unit passage with an externally mounted mechanical oil pressure gauge. To get accurate results from the test, make sure you follow the manufacturer's recommendations and compare your findings to specifications.
Testing the Oil Pressure Gauge

  • Test the gauge by grounding the wire that leads to the sending unit on the block.
  • When the wire is disconnected from the sending unit with the key switch on, the needle on the oil pressure gauge should be either all the way high or all the way low. Grounding the wire should make the needle move to the opposite side of the gauge from where it was before the wire was grounded. If the vehicle is equipped with an oil pressure light, touching the wire to ground and then removing the wire from ground should turn the light on and off.
  • If either happens, the gauge and wiring are good and the sending unit is at fault.
Testing Oil Pressure
Pressure can be tested by temporarily installing an oil pressure gauge in place of the sending unit. Before testing, look up the oil pressure specifications for your vehicle in the appropriate service manual.
  • Bring the engine up to operating temperature.
  • Now shut the engine off.
  • Locate the oil pressure sending unit; usually it is on the lower side of the engine block.
  • Disconnect the wire from the sending unit and use an open ended wrench to remove the sender. Using pliers can damage the unit.

  • Tighten the oil pressure test gauge into the hole in the block where the sender was removed.

  • Check the engine's oil level and fill, if required.
WARNING Be extremely careful when working near a running engine. Always wear safety goggles or glasses with side shields when working around moving machinery and be sure that your clothing is not loose.
  • Now turn the engine on and check the oil pressure on the gauge.
    • Watch as the engine warms to note any excessive drops due to temperature.
    • Make sure the engine speed is set to specifications for testing pressure.
    • If necessary, us a tachometer and adjust the engine idle speed.
  • Record the measured oil pressure, then turn off the engine.
  • Compare the test results with the manufacturer's specifications.
    • If the oil pressure is within specifications, this shows that the oil pressure sending unit may not be working correctly.
    • In many cases, replacing the oil sending unit will correct the problem.
  • After the test is complete, reinstall the oil pressure sending unit, start the engine, and confirm there are no leaks.

SOURCE: Door locks on Ford Expedition stuck

Look under your steering wheel right under the dash. There should be a small white strip with 5 numbers. This is your master code for your vehicle. If you bought the car used and they give you a code, they could have made their own code, but the master will override it. If this don't help, the module for the doors may be going bad.

You should check your blend door, go to the center of your dash look down towards the floor right at the bottom on the hump (tunnel area) you will see a black or same as interior color, cover it has small slits cut in it, it is held in by two expanding type plastic bolts, they do not unscrew, just pull them out, one on each side. Once removed locate the white small box with a wiring harness connected to it, a little to the right hand side. This is the stepping motor that controls the blend door. Remove the stepping motor, and reconnect the harness, look at the motor drive unit and operate the heater control knob, does the motor turn, if it does then use a mirror and look at the drive end of the blend door itself, it is probably broken. If the door is broken, this repair just got difficult, the entire dash will have to be removed to access the environmental station, once accessed there are about 10 screws that hold the top cover on the enviromental station, undo these screws and remove the top cover, then you can remove and replace the blend door. If you are not comfortable with this difficultly level in repair I suggest you seek out your favorite local shop. removing the dash is not easy, there are alot of screws, some in very difficult places to reach. Testing the motor is easy. I hope this helps, let me know.

My 2000 expedition oil pressure needle drops while driving


If the engine is heating up then you need to check the condition of the engine , check the oil , if there is level drop in the sump or if the oil is old and gone too soggy. If so replace with new filter.
However is the engine seems trim and working fine then the oil pressure guage needs a check. Test with an alternative before confirmation or else the oil pump is a suspect at higher temperatures.
