I hope I am understanding your question correctly, but it sounds as though you are asking for a general explanation for what a relay is. All cars, not just an Escort, use relays. Relays are even found in your house. Your refrierator, washing machine, probably your television, and more have relays in them. In a nut shell, a relay is an electrically operated switch. It is a means to use low voltage or low amperage to control high voltage or high amperage. A relay has an electromagnet in it, that when it is energized, moves a contact inside to either make or break an electrical connection. One senerio in a car where this is needed is for the computer(low amperage componet) to operate a radiator cooling fan(high amperage componet). Let's say in our senerio, the engine is hot, and the computer decides to turn on the radiator fan. It supplies low ampere current to the coil windings in the cooling fan relay through two small pins on the relay. This moves the contact inside the relay which completes a circuit across two large pins at the relay to complete a high amperage circuit to the fan and switch the fan on. There are many other relays that perform a host of functions, like turning on the AC compressor, fuel pump, and even operate the starter.

Remove the tailgate trim panel.

Disconnect the remote control rod from the remote control.

Disconnect the negative battery terminal.

Unbolt the latch and remove the remote control.

Disconnect the lock knob rod from the remote control and remove the rod.

Disconnect the lock cylinder rod from the lock cylinder.

Unbolt the remote control and remove it from the liftgate.

Remove 2 nuts that hold the outside handle and take it out of the liftgate.

Installation is the reverse of the removal steps.

It sounds like the thrust race bearing is about to cack it's self, to repair this involves removing the gearbox ripping out the old thrust race replacing it and putting the box back in. this is simple operation requiring little expense on parts.

You will have to replace it with a 97 to 02 2.0L SOHC SPI engine.

The PCV valve is an abbreviation for Positive Crankcase Ventilation, which is the recycling of gases of a vehicle. In a 2002 Ford Escort the PCV valve is located in the front of the engine near the drivers side.

It uses brake fluid in the brake fluid reservoir. The clutch fluid (brake fluid) is fed by the brake fluid reservoir. The clutch fluid reservoir is just beneath the brake fluid reservoir. So, add fluid to the brake fluid reservoir to fill the clutch fluid, also.

Yes. My Mercury Tracer has an engine directly out of a Ford Escort (same year).

the thermostat is located between the thermostat housing and the cylinder head.

To locate the thermostat housing you can follow the upper radiator hose. The part connecting the upper radiator hose to the cylinder head/engine is the thermostat housing. To remove it to access the thermostat will require the use of a 10mm wrench and the draining of the engine coolant

check the idle speed with the car in gear, if it has a tac on the dash it should idle in gear at about 700 rpm if its too low the car will vibrate or stall.

You have to split the transmission, maybe even drop it out. There might be some helpful info on www.autozone.com

On the front of the exhaust manifold you will see your sensor, otherwise, it may be before the catalytic converter on the underside of your car, it helps to go out and buy a special wrench made especially for removing the O2 sensor. Unplug the sensor from it's wiring, then use the wrench to remove the sensor, don't forget to spray it down with a good lubricant such as kroil or wd-40 an let it penetrate for a few minutes before attempting to remove it.

Depends, if you are replacing all fluid it is about 4 to 5 quarts. There is a dip stick for measuring the right amount. Put some in, start the car and run it around the block going through some gears, then park the car, leave it running and check the dip stick. Add more if needed and repeat the process until at the full mark. Use this same process if just adding a little but run the car around the block and check the stick first.

Look on a car like yours.

Look for the light bulb that has 3 wires. Brake light bulbs do double duty. In addition to being a brake light, they are also a tail light.

I had the same problem which I solved by switching on all the other lights [tail and hazards] which left a choice of any one from two. I guessed lucky first time and still don`t know what the fourth bulb is for.

For a 1999 Escort, open the trunk and remove the 2 screws that hold the taillight assembly to the car. Pull the tail light assembly out from the rear a bit and then toward the side of the car. There are two metal nipples lodged in plastic holders farther up the side of the car. These will come out eventually, allowing the whole assembly to come out to replace the bulbs. However, they may stick a bit, requiring some mixture of persistence and force.

You many notice the plastic holders for those nipples on the inside of the trunk. Try to resist the urge to take a large tool and do something to them, as tempting as it is. It isn't necessary.

Once the assembly is loose from the car, you will see the individual bulb holders. Turn the holder counter-clockwise to access the bulb. Remove the bulb carefully by pulling it out of the socket. Push in the new bulb, and reassemble the rest by reversing the above steps.

In my 98 escort wagon, the brake light bulb is located at the lowest position in my tail light assembly.

First off you didn't say why you would want to replace the brake line. I have never worked on a Ford Escort-- but almost all cars are the same. The brake line runing from the front of the car to the back is a metal tubing, and I will assume that is what you are wanting to replace. Usually the tubing hooks to the Master Cylinder at the front, and runs to the back to a "block" of somekind welded or bolted at the rear of the car. The "block" is there to be used to extend the brake lines farther. Usually the tube goes into the block, and than a soft line is ran from the other side of the "block" to the wheel cylinder which is located on the brake drum assembly. This way the soft tube (also part of the brake line system) can flex as the wheel travels up and down, which a hard line can not do. On some cars, that "block" is used to bring the fluid to the back of the car, going into the "block" and than two hard lines come back out and runs to each side of the car, than it goes into another "block" to allow the soft line to be installed to the wheel cylinder. The "block" is more or less an adapter and that's all it does. There is nothing inside those "blocks", its just a point to add more brake lines, that continue onto the wheel cylinder. NOW -- unless the tubing from the front to the back has been damaged, there is no reason to replace it since it is metal. You can disconnect it from the front, and at the rear block, and blow air thur it to make sure it is not clogged. If it isn't clogged than there is no problem with that brake line, unless you can see it leaking. If it is damaged, the first thing you need to do is follow it from front to back to see if it goes under the body and is easy to get to, some cars have the brake line running under the car, some cars have the brake line going thru the tunnel between the front seats and to the back of the car, and some cars have the brake line under the carpeting going to the back of the car. Under the car brake lines are easy to replace, they are usually just held in by clips attached to the frame. If the brake line goes thru the interior, than it maybe a real job to get to it and replace it. The other problem is the year of the car. Unless the dearlership still has factory brake lines for that year, you are kind of in a bind. You can buy brake line tubing and make your own, but you will need the tools to cut and bend the brake lines, and tools to attach the ends that are needed for the brake line, without the tools, you will have to take it to someone with the tools that can do that, you cannot bend the metal brake lines by hand, they kink, that's why you need a tube bender. And you need a flaring tool to be able to attach the ends needed to the brake line, and a tubing cutter to cut the brake line, hacksaws don't work to well for this type of job. I hope this has been of help to you, if you know what your doing, its not hard to replace brake lines or make your own, just takes a little practice.

On many cars you can go to the dealer and he can cut you a key by your giving him the VIN on your car. I assume you have lost your key and don't have one to get a copy made of. Of coure, you can always have a locksmith make you a key from another lock on your car that uses the same key as the ignition. This is what I would do if I didn't have a key to get a copy made of. I think it would be much more economical to have a key made rather than replacing all of the locks on your car.

Replace the fuse and the relay called the CCRM (Constant Control Relay Module).

The dash has to come out to get to the heater core. It's quite a job and this may be a job you want to hire someone else to do. The heater core in my 97 was leaking coolant so I put a small bottle of Alumaseal in the radiator. Some will say this will clog up the radiator, but I have found that not to be the case.

It stopped the leak. I have had no further problems.

check the fuel solenoid is working usually by wriggling the single wire on the top will show if it cuts out if so replace
