I also am checking on a 94 Buick Lesabre and check engine light is on. Engine light comes on after about 10 minutes running, surging up and down,and is running rough at idle. Could you please send me the diagram on how to jump. I got a key from Autozone, but can't figure out where to use it. I have wire down for code reader. I don't see any A and B on it. Please help.

I looked it up and 93 was the last year for jumping A and B on the Assembly Line Diagnostic Connector. In 1994 you need a special set of connectors that are different than the OBDII connectors that are in use after that transition period.
You need to find a store or some who has them.

I am having a similar problem with my climate control buttons. Did you ever find out what the problem was and how to fix it?

On mine it was a switch in the dash. Replaced the switch and both sides worked as they should.

The security light on my 94 LeSabre is flashing! now what? I didn't even take my key out of the ignition when I try to start it, it does nothing. I know it is the security system but what can I do? This is driving me crazy. Thank you.

When you put the key into the ignition and then turn the key to ON, the security light should come on for a few seconds while the VATS reads the resistance of the chip. If it doesn't read the right resistance for the chip, it then flashes for 3 minutes and then resets itself to read the next key inserted.
Do you have a second key? Put it in slowly and then turn the key to ON before turning the key to START. See what the Security light does.
The resistance it reads may be wrong because
the contacts inside the entrance to the key cylinder that contact the two sides of the key resistor are worn or dirty. You can try putting alcohol on the resistor parts of the key and quickly insert it to clean the with the alcohol carried in.
The resistor on the key may be gooey or oiley. Rub it with a pencil eraser to remove goop on the two resistor contacts.
The two wires that go from the contacts inside the key cylinder down the steering column to the connector at the base may have broken some of the fine wires where they bend all the time as the tilt wheel goes up and down.
If it reads the key resistance as correct, it will then start the car. It may still have problems. The light may come on while you're driving if and then go off again.
The dealer will want to replace the lock cylinder and cut new keys for that cylinder at $30 each. I would expect $300 at some dealers. Independent garages may charge less that are knowledgeable.
There is a fix where resistors equal to the key resistance are soldered into the circuit down on the steering column instead of the contacts reading the key in the cylinder at the top. Then you have no theft deterrent but the VATS system always works. (VATS=vehicle anti theft system).
#43 of 75 1997 lesabre struts
Sep 26, 2008 (6:04 am)
With only 42000 miles on my mothers Lesabre she needs to replace all four struts. Bought new, the little old lady type driver, driving on main roads - what do you think would be the reason for the strut replacement ? I have driven the car and checked it out and they do need to be replaced. The car has not been hurt and well maintained. Have there been past problems or recalls? Thank you for your input time.

To what are you comparing the struts?
The Buicks had a very soft, but controlled ride. They are at home on a relatively smooth street and interstate. If it's a Custom, that's even more true because it doesn't have the leveling rear struts that pump up to maintain height. Those were actually stiffer than the base struts for the rear. In the 1993, with two people in the rear, stopping at a stop sign quickly and making the nose dive then hitting the gas actually threw enough mass to the rear that the struts bottom (softly).
If you're comparing to an Accord's ride, that won't work as you see from what I've said. If you mother intends to keep the car I'd do as I did on both my leSabres and put on Monroe SensaTrac stuts all around. You can shop for price. I don't recommend Sears but another store would match their pricing. Sears runs half price on installation labor cost fairly often and you can take that plus the cost of the struts to shop at your favorite place. Don't forget there'll be a 4-wheel alignment added to that.
Eleven years of age may also have softened the struts.

Thanks very much for the input. I guess I am use to driving my Honda Pilot having a stiffer ride. I will pass on your recomondation and she will probably go with that. Thanks again for your time and input.

I have a 93' Lesabre and the other day I pulled the codes from the computer and I am trying to clear them. I was wondering where exactly the ECM fuse is located under the hood? Thanks
