Buick LeSabre

That GM car uses a system called VATS

Your key should have a chip in it. You need to take an OHMS meter and check the resistance on both sides of the chip in the key. From that, you will need to buy a resistor that matches the resistance on the key

You will Cut the Vats system wires that run up into the steering column. It should be two wires that are wrapped in orange plastic. You will need to solder the resister into the harness side of the wires.

Please ask a complete question if you need an answer.

AutoZone posts wiring diagrams for many cars and trucks for free. It also has a vast amount of repair information, including diagrams of part locations, detailed instructions, etc. If you don't have a repair manual for your car, you can just about get by with this all by itself. However, not all cars are covered by this service. You'll just have to look and see if yours is.

Follow this link: www.autozone.com/shopping/vehicleSelect1.htm. Then select your year and make/model of car.

Now do the following: * Locate your car, year, make and model. * Select "Repair Info" at the left side of the screen. * Then select, "Vehicle Repair Guides" -> Chassis Electrical -> Wiring Diagrams

There could be a possible fuse blown some where?...check the fuses for marking lights You may also want to look for the turn signal relay, try putting on your 4-way hazard flashers and see if those work, if they do you can here the clicking noise of the relay, might be under your dash. In my car it was underneath the dash directly in line with the steering column, above the brake pedal.

The short answer is no. Autozone: Duralast 100-DLG $112 Advance Auto, Checker, Schuck's, or Kragen: Autocraft-1001 $100 Keep in mind that car batteries are a commodity item, and there about/only three manufacturers that make most of the batteries sold. So look for the cold cranking amps [CCA], bigger is better. There is nothing special about a GM battery, a dealer is full of hot air if they tell you other wise. It's a re-branded battery from one of the big three battery manufacturers. For example, Johnson Controls, who is one of the big three manufacturers, makes AutoZone Duralast, CostCo's Kirkland, Ford's Motorcraft, Interstate, Sears Diehard, among others [they even make Bosch and Varta] car batteries. No. I bought one from Wal-Mart. Most retail stores and "chain" auto parts stores like Napa, Pep Boys, etc. should have one in stock. Although the dealer is always the best choice for parts and/or service you don't have to buy there as long as your purchase is equal to O.E. (original equipment) you should be fine buying from a reputable retalier such as Sears, Kmart Pepboys, AutoZone, etc.--- P.S. Consult store personnel on the correct battery for your vehicle.

Im trying to bypass the security sensor so my car will start 1995 buick lasabre

===========

The "Sensor" itself consists of a couple of metal fingers that grab the flat of the key on either side of the little 'chip' (it's actually just a piece of metal that has a particular resistance matched to your Security Module). These fingers are in the moveable part of the key receptacle in the steering column. The wires connected to these fingers often break, and a standard 'fix' is to spoof the system with a resistor that electrically looks just like your key.

The wires come out of the bottom of the steering column, and can be snipped there and the proper resistor soldered in. I can't remember which wires they are right now -sorry! But this may be enough for you to go on with additional 'net searching.

The module on a '92 is behind the glove box. Don't know about the '95.

Not knowing what year your car is I'll have to guess that it's a post 1996 with a VATS OEM anti-theft device. That would indicate that the VATS signal was correct at startup but failed while you were driving the vehicle. The constant light indicates that the VATS is in "Failed Enable" mode meaning that there is no more immobilizer protecting your vehicle usually caused by a worn ignition barrel. If your car is 10 years old and aren't worry by theft then don't worry about it, it won't leave you stranded. If you have several hundred dollars burning a hole in your pocket then take it to a repair shop. There's nothing you can do yourself.

The fuel filter is on the frame just forward of the gas tank.

throttle body" fuel", cooling system separate.

On a 3.8 engine the throttle body and upper plenum contain coolant. There is a gasket between them that could leak. More important the upper pleninum on the 3.8 engine often develops a leak near the EGR inlet which is in the area you are concerned with.

The Idle Air Control valve is located on the side of the throttle plate. Normally the only problem they have is getting gummed up and need a good cleaning.

the quad driver module is part of your computer, it controls certain parts like your emission system and fuel system that sort of stuff.

Immidiately to the left of the steering wheel, below the traction control switch/twilight sentinel/interior light dimmer controls. Note that the trunk button can be disabled by a switch in the glove box or another switch in the trunk on the locking mechanism itself.

Under the back seat

It has a chain.

The 1993 Bucik LeSabre takes 22" wiper blades on both sides front. See sources and related links below for more information. Since there are over 22 different wiper arm attachments, do not buy wipers just by length only - be sure to lookup exact wiper blade part numbers by vehicle make, model and year for the brand wiper you decide to purchase. This ensures correct length AND correct attachment.

Brake fluid could be low or emergency brake might be partly on.

I'd check your fluid right away. This just happened to me and i found out it was my rear driver side break like had rusted out. could be the same thing for you.

Alright, let's begin the madness: 1. Take your DMM, set it to measure Ohms (use the 20k setting.) Measure the resistance across the pellet of the ignition key. Place one probe on the silver part of one side of the pellet, and the other probe on the other side. Write this value down. 2. Purchase a resistor or resistors that add up to the value measured in step 1. Radio Shack is a great place to go for the resistors, heat shrink tubing, and the "bullet-style" solderless connectors. 3. Take the 16 ga. wire and cut into 2 four-inch pieces. 4. Strip off approx 1/16" of insulation off each side of both wire pieces. 5. Put your resistors together in series (or if you're lucky and have a chip that has a resistance that matches a single resistor) and solder one wire to one end of the resistor(s) and the other wire to the other side. Example: You measure 11.72 on the 20k (k meaning kilo or 1,000) scale. The closest match is 11.801 which is a #15 "chip." Always remember that resistors have a tolerance of 2%, meaning the resistance value of the "pellet" can be either 2% higher or 2% lower than 11.801 k ohms (11.72 falls in tolerance range.) You will want to aim for 11,801 ohms. So when you go to Radio Shack you want to pick up a 10,000 ohm (10k,) a 1,000 ohm (1k,) and an 800 ohm resistors to wire together in series to achieve the 11.801k ohm value. Here's an example of how you'd connect the above mentioned resistors in "series" wire------10k ohm------I------1k ohm------I------800 ohm------wire 6. Measure the resistance across the 2 wires now that the resistors are soldered to them. Be absolutely sure the value matches that of the resistor pellet in the ignition key (within 2% up or down.) 7. Cut a length of heat-shrink tubing to cover up the resistors, allowing a small bit to hang over onto each of the 2 wires. Use a lighter or heat gun to shrink the tubing. 8. On one of the wires, crimp on a male bullet connector, and on the other wire crimp on a female bullet connector. 9. Now what you have should look like this: Notice in the above "resistor pack" I lucked out and only needed 1 resistor to match the pellet's resistance. You may not be so lucky... 10. Now move to the car. Remove the under-dash kick panel. 11. Look for an orange wire running down the steering column. This wire should have a "rubbery" feel to it, and it is the only orange wire running from the column. **WARNING** Do not tamper with any of the wires near the column wrapped in yellow harness tape or any yellow wire. These wires are for the airbag. Tampering with any of these wires could result in the airbag discharging. 12. Cut this wire (there are 2 small wires inside) and strip back the insulation on the wires on the opposite side of the steering column. 13. Install a male bullet connector to one of the 2 wires, and a female on the other. 14. Plug in your "resistor pack" that you made by mating the male and female bullet connectors. 15. Attempt to start the car. If your problem was with the VATS reader in the ignition lock cylinder, this will start the car. If this won't start the car, then the problem is in the VATS module. If the VATS module is bad, remove the resistor pack. Strip the insulation off the other side of the main wire cut (running from the column) and place a male connector on one wire and a female on the other. Plug the 2 halves back together to restore the function of the VATS reader. Alright, let's begin the madness: 1. Take your DMM, set it to measure Ohms (use the 20k setting.)

To my knowledge all thermoststs are located at the end of the top radiator hose !

The battery in your 2002 Buick LeSabre (and probably all LeSabres that share the same body style, 2000-2005) is located under the rear seat. To reach it you simply pop out the rear seat cushion by pushing in at the bottom and lifting. It's a special battery with vents that connect to a vent hose the other end of which goes through the floor pan to the outside. When reinstalling be very sure that the vent hose is in good condition and properly connected to the battery. The hydrogen sulfide fumes fom a lead/acid battery can attack the seat cushion or eat a hole in the floor, not to mention being highly flammable. When I had to replace mine I discovered that not all battery shops carry the proper battery for this vehicle. The best price I could find actually was at a Buick dealership for an OEM battery (which has held up quite well). Do not try to "cheap out" and substitute a "normal" battery. It will end up costing you more and could potentially be very dangerous.

Check the belts. The most common cause of squealing is a worn or loose belt on the front of the engine.
