1989 Ford Crown Victoria - Answered Questions & Fixed issues

I had the same problem its either the light switch or a loose connection going to the switch I could reach up in the dash and wiggle the wires going to the light switch and mine would come on

it should under the lid of the fuse box and in the owners manual if no manual try here for one online www.edmonds.com

Rays correct your fuse box is located to the left side of the steering column under it near the emergency brake and it may have a plastic cover over it with a rounded upper right corner for the flasher

until you can see the leak its still guess work --either mechanic didnt do repair correctly or you have a crack in block --use a mirror and light to look in area for origin of leak

Remove the door inner trim panel , and reinstall the linkage rod.

Bill, you could possibly have a vacuum hose leak. With motor running, open your hood and listen carefully for a hissing sound. If you hear one, try to pinpoint where it's coming from.

Usually the problem is inside the lock switch. You should have power at the EEC relay and the coil with the switch in the on position.

depends which freeze plugs your changing. if its the ones at the rear of the heads or back of motor being covered by the bell housing then yes it has to be pulled.

Yes, you have to pull the transmission. But look it over closely. Most likely the coolant is coming from somewhere else. I have never seen or replaced a bad freeze plug back there. Water can't get to them to rust them out from the outside in. Only if you use water only to cool the engine. Heater hoses and the intake manifold gaskets can cause a leak in this area.

these can be found in a Chiltons book or by Google search for motor size

Usually the Crown Vics and MGM's (Mercury Grand Marquis) have them behind the wheel well of the passenger side, or mounted low on the engine compartment

when all else fails replace the ignition module on the distributor. As it fails it will cause high idle and other symptoms. Does the problem only happen when the engine is hot?

Ford puts all the ECM/PCM's in the firewall on the passenger side.

Nine times out of ten, it is the sending unit in the tank that is the problem. To check, use a sort jumper wire to ground the gas gauge wire to the frame while watching the gauge needle on the dash, with the key in on position. Find the gas tank electrical connector by the tank. Pull it apart, and on the harness side of the connector, locate the wire going to the sending unit. I don't know what color it is, but the fuel pump wire is a pink wire with black stripe and there is a black wire for the ground. The other wire should be for the dash gauge's sending unit. Have a helper turn the key to on and watch the gas gauge for any perceptible movement while you use the jumper wire, insert one end into the terminal for the gauge's sending unit wire (this is on the harness side of the connector, not the gas tank side), and touch the other end to the car frame-you are grounding it. If the dash gauge is good, the needle should move a lot, usually will move more than half way, one way or the other. So if it does, you know the dash gauge is good, and the problem is in the sending unit. If it is the sending unit, it is quite a job to drop the tank, pull it out from under the car, then pull the fuel pump and sending unit out. You might be fighting a lot of rust on an '89-get some penetrating oil. And look for the removal procedure in a repair manual. It's not terribly difficult if you are handy with tools...and like to get dirty. Those hoses on the tank have been stuck on there a long time. Good luck.

have the OBD codes read , there may be no fault but the codes might just need clearing , like all computers they can get a bit confused

1. Start engine 2. allow to idle 3. remove fuel pump fuse while engine running 4. with fuse still removed restart 1-3 more times to clear any fuel from system. System D/P'd.

check the pressure in the fuel pressure port in the injector rail assembly (looks like valve in the taller for the air)

You can not clean them they are sealed in molded plastic. Buy a new one, tem min job to replace.

remove the interior door trim and replace the small connection from the outside door handle to the lock. It is held in place by a plastic clip that breaks on a regular basis.
