Yes, IMMEDIATELY within 3 seconds after punching in your code, hit the 5 on your pad and your trunk will pop open. also if you immediately hit the 4 the other three doors will unlock.

If the car is on a hoist it is easier. With the car on jack stands and you on your back, very, very hard. You need small hands, or send the car off to someone with a hoist.

(Licenced Technician) -- Loose steering / wander can be caused by almost anything; bad alignment to worn steering linkage to bad balljoints to broken springs, worn steering gear, incorrect tire pressure (too high or too low), worn / mismatched tires, even wear in the steering column can cause this. In extreme cases, I have seen vehicles that would not drive properly, even with a front end that was 100% and an alignment that was all in spec. It turned out the vehicle's frame was still damaged after an accident. I would strongly recommend getting this professionally checked; a 1994 GM likely still has original (read: non-greaseable) front end joints and are likely getting play in them. .

You don't. It is a sealed unit.

In the relay box next to all the other relays.

Most likely cause would be a blown fuse.

( 6 quarts with filter change ) according to the owners manual

( 20 U.S. gallons ) according to my Chilton's book ( for a 1988 Mercury Grand

Marquis )

@150K, there is a Strong chance that you have low oil pressure. As such, there is a electronic oil pressure sending unit on the lower front right side of the block. Unplug it for a few seconds. If your check engine light goes away, theres your problem. I personally would hook up a $17 manual oil pressure guage just to be safe. As for the cruise controll problem, this is a common problem. just outside of the transmission, there is an electrical attachment to a vehicle speed sensor. Check both the wires leading into it and the connctions at the sensor itself. Replace at your descretion. As for the o2 sensor, it is possible, but not likely. o2 sensors will rarely set of a trouble code on an EFI motor unless you have a cylinder not firing.

with a socket set

The ( 2007 ) Mercury Grand Marquis has a ( 19 U.S. gallon tank )

In the trunk

that depends how you drive the miles on the car how the car has been maitained how the car runs the tires and the gas you use

Here is a handy trick to bypass that problem. Once running, turn the key slightly pass the start position. You don't have to go so far as to here your starter grinding. As you are doing this you should be trying to shift out of park. Sorry I can't guide your fix.

p1131 = lack of HO2S11 switches - sensor indicates lean

This is a tricky interview question. You don't want to appear that there is anything you can't do. Put a positive spin on it like, 'I found it hard not to get too involved with the customers.' or 'I found it difficult to not think about work at home.' These are neutral statements that won't slant the interview negatively.

no

Leave it in o/d . The trans. will work just fine.

As on many cars these days, we often can be "bumped" in the rear while parked or otherwise and this can shut down the fuel system temporarily. Open your trunk lid and on the left side(fender area) there is a box or compartment cover. Just look around for it, its there... Inside there is a reset button... just press it and your vehicle should restart. Anything beyond this may r4equire the assistance of a mechanic..blah, blah...

Remove the black plastic piece that holds the courtesy light under the dash. There are 2 screws that hold the LCM to the bracket. The LCM is just above and in front the diagnostic Data Link for those who want to know. You can reach up and press the wiring harness connector clips and pull the connectors to the front of the car. Then release the plastic latch on the underside of he LCM.

Move the LCM forward and turn it up and sideways and it will clear everything. It is tight, but it will clear. I have changed about 5 of these this way, all on 2003 MM and CV's.

It seems 03's lose the headlight relay and make the headlights cycle on/off when it gets hot outside or the heater is on full blast (at least out here in the desert). Good luck.

Fuse number 23 in the passenger compartment box is blown. It caused the following devices to stop working: Door lock switches (but not the locks), Interior lights, radio lights, A/C climate control, overhead console quit.

According to the 1996 Mercury Grand Marquis Owner Guide :

( DOT 3 brake fluid , meeting Ford specification ESA-M6C25-A )

Turn the switch to on, then under the steering column cover below the switch is a hole. You push a pin in to release the switch. You'll have to fish around to get the spot where the pin is. Or take the bottom cover off to see it better.
