Lincoln Navigator

The PVC hose is on the passenger side valve cover. Its fits into the valve cover. It has a hose (vaccum) coming off of it going two different ways.

You can order a new one at NAPA auto parts.

I just checked mine out and found a button next to the left headphone plug. It seems the buttom will either let you use headphones or speakers but not both. Hope this helps.

If check engine light is on, have a parts store read the code. It will tell you there is a random misfire and usually what cylinder is misfiring. Replace the coil pack for that cylinder and all will be well.

You probably have a door sensor out, they detect whether or not the doors are closed, so the car thinks a door is open. It is a little button that gets pushed in by the front of the door by the hinges. They are cheap and easy to replace.

There are three of them. One is located in each front wheel opening. The upper portion of the sensor is mounted to the upper control arm and the lower portion is mounted to a bracket which is mounted to the inner wheel apron. In order to change/lower the ride height in the front of the car you have to COMPRESS or shorten the sensor by moving the lower portion of the sensor UPWARDS. This is done by loosening the bolt that holds the bracket which is monted to the wheel apron and moviing it up and then tightening the bolt again. YOU MUST BE CERTAIN THAT YOU HAVE A LEVEL CAR ONCE YOU MOVE THESE BRACKETS AROUND and then you have to have the casr realigned or you will wear tires and cause excessive stress on the front suspension components... The rear sensor is on the left rear of the car and the lower portion of the sensor is mounted to the left lower control arm and the upper portion is mounted to a bracket which is bolted to the inner car body. In order to change/lower the ride height of the rear you must EXTEND the sensor by moving the upper mounting bracket UP. Again, an alignment must be done to avoid stress on susension parts and excessive and improper tire wear.

It depends on the relay. Call local parts store for actual prices.

they are under a panel by the fuel rails. they are very hard to get to.

You need 3/8 Allen key.

lets assuming the radio is turning on and there's is no sound at all coming from the radio, CD or tape

here's are three possible answer

1) make sure your radio is not on mute

2) make sure the volume is on position and its in the desire level of sound

3) make sure you have no lose wiring connection from your radio through your speakers. and also check if there's any fuses attached to your wire from your radio

It is located on the firewall just above the fuse box on the driver's side. I had to almost lay down with a flashlight and squint with one eye open, but it's there. Under steering wheel left side of it , had to use a camera on my phone to take picture of white sticker with 5 digit code. It's back there a ways. Awkward position to lay down to see it but it's up there..9/11/14

If your refering to the engine light been on. Auto Zone will check the codes for FREE. If other lights then we need more details...

Generally the running water sound under the dash is air trapped in the coolant system. This air then circulates through the heater core. Just check the coolant level in the radiator and make sure the overflow reservoir is full. Run a few heating and cooling cycles of the engine and recheck. This should help take care of the sound.

Can anyone tell us where the lines are to refill the freon in a navigator

no

Hi,

I just did mine on an expedition. There are two flat retaining clips that hold the front plastic cap on the assembly. Move the mirror to its full inward position. Then you can reach in with a flat screw driver and lift up the one clip. Tilt the mirror to the other full extreme then you can reach in and free the other clip. With the top two free, the bottom slides out and you have access to the bulb.

There is plugs on the end of the speaker wires. "The wires coming from the subwoofer box. There should be to wires coming from the sub enclosure". These wires should have a plastic plug on the end that plugs in to the amplifier.

I just did this on my '99 RAV4. Very simple. With the hood open, you'll see a large black plastic "box" on the mid-right hand side. There are two metal clips on the right hand side of it holding the lid closed. Pop them open and lift the top which bends back to the left. You'll have to use a little force and manouver since there is a hose attached on the left but it bends. Pull the old filter out, slip in the new one. Top down, clips back on. Done. Just be sure that you haven't dislodged the cap on something right in front of the air filter box. Not sure what it is - for coolant? It's a small cap I noticed popped off when I pulled the air filter lid back. Just put it back on if it comes off. Maybe mine wasn't securely tightened to begin with.

the tumblers in your key switch are failing replace them before long

Door Code Location...

I actually found the door code behind the fuse box area (Driver Side) on my brother's 2000 Ford Expedition EB. There is a big white sticker with 5 numbers starting with number 1####. Hope this helps...

5 on 135.

firewall 4 - 8 3 - 7 2 - 6 1 - 5 front

all navigators only require reg fuel

According to the 2004 Lincoln Navigator Owner Guide :

( the engine is designed to run on " premium " unleaded gasoline , 91 octane or higher )

FUEL PUMP SHUT-OFF SWITCH After a collision, if the engine cranks but does not start, the fuel pump shut-off switch may have been activated. The "Fuel Reset" indicator light will illuminate in the instrument cluster. The shut-off switch is a device intended to stop the electric fuel pump when your vehicle has been involved in a substantial jolt. 1. Turn the ignition to the OFF position. 2. Check the fuel system for leaks. 3. If no fuel leak is apparent, reset the fuel pump shut-off switch by pushing in the reset button. 4. Turn the ignition to the ON position. Pause for a few seconds and return the key to the OFF position. 5. Make a further check for leaks in the fuel system. Roadside emergencies The fuel pump shut-off switch is located in the passenger's foot well, behind the kick panel.
