Top 10 1998 Ford Mustang Questions & Answers

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

The 1994-98 Mustang vehicles are equipped with two fuse boxes, or locations: the fuse junction panel and the power distribution box.
The fuse junction panel is located under the left-hand side of the instrument panel and is an integral part of the chassis wiring harness. The fuse junction panel contains only some of the fuses and circuit breakers for the vehicle.


The indicator flasher and fuse junction panel are located under the left-hand side of the instrument panel, to the left of the steering column

The other location for fuses and relays is the power distribution box, which is located in the engine compartment on the left-hand, front fender apron. This box contains the high power fuses and was designed to take the place of most of the fusible links.


Note that the identification of the fuses and relays is embossed into the power distribution box cover

Im not 100 percent but I would check the underhood fusebox. The lid should have a diagram stating the jobs of all of the fuses.

Make sure the parking brake is engaged first. Then just push the button next to the parjing brake.

If the antitheft light is blinking then the pcm is not getting a signal from the PATS transponder. The Check transponder ring, wiring, PCM fuse in under the hood fuse panel, and lastly pcm. Good luck.

2 plugs on each side of the motor, under the exhaust manifold center of block you cant miss them. Tap them gently on the sides to turn them, then pry them off. Do not drop them inside the engine thus they are impossible to remove.

For this vehicle, check ...



I hope this helps (remember to rate this answer).

First thing to note is that the relay is housed in a Constant Control Relay Module (CCRM). This module contains the relay for the Fuel Pump, Cooling Fan, and Air Conditioning Clutch.

In our 1998 Mustang V6, the location of the CCRM is behind the passenger side wheel well plastic cover. Looking at the wheel dead on - it's found at around the 1 o'clock position. To confirm it's location without removing any plastic wheel well cover - pop the hood, and look for a wire harness routing from the engine compartment INTO the passenger side front fender (near the air cleaner). Flash a light in there, and you'll see a connector attached to the module.

I'll save you some headaches in finding the right size tool to remove the connector as well - I used a 5mm nut wrench to remove the connector from the module. Do this first so that you can access one of the two bolts that holds the module bracket to the fender. found this at the allfordmustangs web site. hope this helps

The Cooling Fan Motor Relay(s) are INTEGRAL part in the Constant Control Relay Module ((CCRM).
Here is the location of the CCRM....

The oxygen sensors are located in 4 positions Bank 1 is the passenger side of the vehicle on Ford's 2 driver side. Bank 1 sensor 1 is at the bottom of the exhaust manifold where it connects to the exhaust pipes. Bank 1 sensor 2 is underneath the vehicle just past the catalytic convertor. Bank 2 is exactly the same as one but obviously on the other side.
