1997 Buick LeSabre - Answered Questions & Fixed issues

My only thought right now is a dirty mass air flow sensor. Beyond that it would require a scan tool on the transmission to detect if pressures are correct.

I would check under the dash to see if a hose has come disconnected for the middle vents

5 or 6 bolts on top one on bottom usually have to open passenger door to see it one bottom front bumper may hide it

DO NOT DRILL A HOLE! Drop the tank! Your basically guessing when you drill the hole AND the heat generated by the drill could ignite any fuel that is in the tank! If there isn't an access panel under the rear seats, dropping the tank is the ONLY safe way to do this. It's a pain in the tail-bone job but its the safest method.

If your security warning light is on and it's refusing to start it is most likely that the anti-theft system has been triggered. Go back to the basics first. Some of these will sound obvious. Is it the correct key? Is the battery in the key fob working, (Does it work the door locks)? Is the battery on the vehicle fully charged? Has the battery been disconnected recently? If all of these are OK then there must be a more serious issue. All I can suggest is contacting a Good Auto Electrician and get him to scan the cars OBD2 system for trouble codes as clues to the problem. *NOTE* get quotes from a few Auto Electricians as the fees they charge can be very different.

Low pressure switch for WHAT?

Need to know engine size

If i remember correctly the entire rear light assembly must be remove in order to access these bulbs. This is true if the license plate is on the trunk. If this is the case then there are nuts on the inside of the trunk that must be removed.

There should be a fuse panel behind the glove box. You'll have to access it by pulling the rubber tabs inward to allow the glove box to pop out. Also, check the fuses on the driver's side fuse panel.

The fuse box locations and there diagrams are in the owners manual. If you don't have one you can download one at the GM site for free. Here is the LINK

How to change the air conditioning bolt that is broke in the. Bracket

You must take it to a dealership and they will unlock it for you. There is a specific dealer code that will unlock any radio and once they do it, you pick one that you will remember. This is part of the anti theft. Hope this helps.

Stay by checking your fuses. Also see if the hazards work.

Sounds like what is called shutter changing to synthetic fluid fixed my 98 Lesabre

Checale los fusibles abajo del lado del copiloto trae algunos incluyendo el del la bomba de la gasolina o hay un rele ahi tambi?n de encendido puede ser el sensor del cig?e?al tambi?n Checa que este bien el arn?s trae m?s fusibles del lado del conductor y otros m?s abajo del capo abajo de los limpiaparabrisas

On this website you find fuse box diagram for Buick LaSabre (1997) http://www.carknowledge.info/buick-lesabre-1996-1998-fuse-box-diagram

I HAD THE SAME PROBLEM IN ANOTHER BUICK . IT WAS THE COMAND MODUEL BEHIND THE GLOVE COMPARTMENT, THE SPRINGS THAT OPEN AND CLOSE AIR FLOW WINDOWS
THAT RUN FROM THE UNIT WON'T CHANGE FROM HEAT TO AIR TO YOUR VENTS.YOU NEED A NEW COMAND MODUEL OR HAVE IT REBUILT . IT OPENS AND CLOSES THE VENT DOORS . I GOT MINE REBUILT FOR $50.00 FROM A GUY THAT WORKED AIRCON LINE @GM
GARAGE QUOTED ME $650.00 HOPE THIS HELPS.
GOOD LUCK

I really don't think you would have a fuse problem . You should hope not anyway , fuse's don't go bad or blow for no reason . A blown fuse would be caused by a direct short to ground on a battery power supply circuit , high current draw . I would look at the flasher or switch as probable cause . Viewing a wiring diagram an testing the electrical circuits is the best way to find the problem . Turn Lamps With the ignition switch in the RUN position, battery positive voltage (B+) is supplied from the IP fuse block T/SIG/BU LP/BTSI fuse 1B via CKT 539 (PNK) through the turn signal flasher to the normally closed switch in the turn/hazard switch via CKT 16 (PPL). With the turn switch in the left turn position, battery positive voltage (B+) is applied through the turn switch and two paths to the turn lamps. One path is to the left front park/turn lamps and the side marker lamps via CKT 14 (LT BLU). The second path is supplied to the left tail/stop/turn lamps via CKT 18 (YEL). The lamps go on immediately. The lights begin to flash when the current heats up the timing element in the flasher, and the flasher repeatedly opens and closes the circuit. A similar procedure is followed when the turn switch is in the right turn position. Battery positive voltage (B+) is supplied to the right front park/turn lamps and the side marker lamps via CKT 15 (DK BLU). Battery positive voltage (B+) is supplied to the right tail/stop/turn lamps via CKT 19 (DK GRN). http://www.bbbind.com/free-tsb

if you are not a professional with the necessary equipment and training, your best bet is to not mess with it, because it could kill you. The term "airbag" Is a misnomer; because it is not an airbag, it is an explosive device and if you do the wrong thing, it could blow up in your face. Sodium azide is the chemical found in automobile airbags. An electrical charge triggered by automobile impact causes sodium azide to explode and convert to nitrogen gas inside the airbag. Actually, there has been an occurrence where an airbag exploded while being installed before the wires were connected. It was set off by the static charge from friction between the mechanics pants on the seat upholstery
