Hi Joe,here's a link to what the oil pressure switch look's like,it's screwed into engine block by oil filter,easy to remove.

thats is two different problems. the blower motor resistor is bad causing it not to work on the lower setting just high. now on the defrost not working could be the blend door actuator but to figure it out you will need to be diagnosed by a professional. it is a little more involved. but the blower resistor is fairly easy

let me know if you have any ore question

The horn and lights are not controlled by the key switch.It sounds like the switch has failed or you have lost power to it from the battery.Have you checked the fuses and the key switch with a meter ?

Ckeck the headlight connections they are notorious for corroding. Check the ground connection for the lights. Pull your dimmer switch back as if you were flashing a car to pass and see if they work there. If they do you have a dimmer switch problem.

The other thing that you need is a ground signal.. I believe that is supplied by the switch and the body control module on this model.You may be money ahead to have a reputable repair facility perform the diagnostics needed to keep from "throwing" more parts at it.

A smoking engine could be to an oil problem or a cooling problem in the engine, the radio not working may be wires got burned-----------------------------------------------------------------------------------auto hid xenon light

If it is blowing air at different speeds inside the car, I think you are saying the blower works fine, but blows no heat. If it is running different speeds but is not blowing inside the car, you probably have a plastic flap inside the heater assembly inside the car that is not opening, not allowing the air to come in. That might likely be a vacuum issue, or maybe a mechanical one. (whatever is supposed to open the flap)If the flap is working and you are getting different amounts of air inside the car according to the speed of the blower fan setting you have selected, go to the engine temperature.Is the radiator getting hot? Have you a temperature gauge to tell if the engine is hot? If not, you will need to warm up the engine, and then determine if there is hot water in the radiator. If you pull off the cap to see, it could blow up on your face, so you will need to find someone who can help you with this. If the radiator is hot after about 10-15 minutes of the motor running, you are perhaps not getting hot water to the heater. You would need to check the temperature control to see if it is working. This is often a mechanical switch located near the firewall of the Jeep under the hood. Usually it is the size of a small fist, and has a heater hose running into and out of it, and has a wire attached to the top.It might have a wire to it that should move when you select hot or cold inside the jeep at the control panel. Sometimes the control wire will rust or break.. The heater hoses should be hot if the hot water is running through them.If your radiator is low on coolant, often the heater inside the car will not work.

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

THE CHECK ENGINE LIGHT COMES ON WHEN THE ONBOARD COMPUTER HAS DETECTED A PROMLEM. YOU NEED TO HAVE IT CKD FOR STORED CODES. ANY REPUTABLE SHOP CAN DO THIS FOR YOU AND TELL YOU WHAT THE CODES MEAN. IF THE LIGHT IS ON STEADY YOU NEED TO HAVE THIS CHECKED AS SOON AS POSSIBLE.WITH THE LIGHT ON YOU ARE DRIVING IN WHAT IS CALLED LIMP HOME MODE ,THE COMPUTER GOES INTO A BASIC FUNCTION MODE AND .CAN CAUSE DAMAGE. HOPE THIS HELPS BILL

Did you replace any parts, or did the clutch pedal just go out?

try flushing the heater core should be two rubber hoses feeding into the firewall disconnect both hoses and flush with garden hose in bothe directions multiple times

Sounds like the Mass Airflow sensor (or MAF).

Not sure about the gauges problem, but "No Bus" means that the PCM or the computer can not communicate.

Have the light turned off,try disconnecting the batteryor use a code readerI assume you have some understanding ofvehicle maintenance & have your own schedulefor all your vehiclesIt will come on again possibly at 120,000forget it,just do what ever you do or needs to be doneJust a manufacture gadget to get you into a dealerso you can bend over
