SOURCE: Buick LeSabre left front window will not close

Don it. Good half day for amateur. Get Chilton 86-99 Bonneville, 88, Lesabre manuel.. Tricky to find bolts are under end flaps on door close handgrips. Took me a day to figure that one out. Others under light at lip of back of door. Book indicates to strart with window 3/4 up if you can. Flip up window control at rear of panel. After all screws are out raise outer edge of armrest and look for notches 4" and 11-1/2" from rear of armrest to slide inward to remove. There are screws under the door handle too. Screws everwhere. When pulling bottom of panel from door lift with a notched bar to avoid tearing the fasteners out of the cardboard panel. Two screws behind seatbelt notch at top need to come out to allow positioning the glass. The panel at the bottom of the top opening can be removed for more fredom in positioning the glass when reinserting the ball in the lower track on the window. Tape glass with duct tape to keep it from falling. Drill the factory rivets that hold the old regulator and I replaced with stove bolts with nylon locknuts slotted head to the inside the car. Can't remember the size, probably 1/4 or 3/16". Remove speaker if in front bottom of door to use your hand to do work in the door. You must twist the regulator forward with window 1/2 down to remove the ball from the socket in the bottom sliding metal track at the bottom of the window. Don't drop the window after removing the socket, tape it in place. Don't know what you do if you cannot move it to 1/2 up position. By the way, the body shops say you must use rivets, not screws or it will shift, but I have had no problems with the screws for reinstallation several years old. The rivet they use take a big hydraulic pop rivet gun that you won't have. Good luck, I don't envy you. Need to do other window on my 91. The window control may not be the same on the Custom, mine is the Ltd. you may be able to remove the motor from the regulator in the door without removing the regulator if you can figure out how to get the bolts that hold the moter to the regulator. inside the door.

SOURCE: 1998 Buick Lesabre How do you test the coil packs?

the coils are one integrated block with 3 separate segments. the coil pack is mounted to the ignition module and can be unbolted from each other. one can test the coils from the underside of the coilpack with a dvom. having said that your car should still start if one paired coil fails, it would however miss on one or two cylinders. I would suggest to scan for codes, monitor live sensor data to see if you have a valid crank signal, check fuel pressure and spark voltage

SOURCE: 2000 Buick Lesabre custom liscense plate bulb

kind of tricky, took me an hour to get it figured out, but you got to opend the trunk and take out the 10 or so 10mm nuts sticking out of the backside of the lid, then the whole solid piece where the lights are on the back will slide off, then you can change the bulbs above the license plate and put it all back together

ECM would be the next part. Check the number on it . If it has the number 1228253 replace it anyway because they give a cutting off problem. Clean battery cables all three and replace bolts too.

Check the ECM if it has the number 1228253 on it, this is what is wrong with it. Gm trashed all of these bad ecms. Get a 16198264 as they do not cause a cutting off problem . Get a delco ecm , aftermarket units will give trouble and may be a rebuilt 1228253 which is junk.

1998 BUICK LESABRE CUTS OFF WHILE DRIVING


The problem is the crankshaft sensor for sure. It is mounted behind the crankshaft pulley which is pretty difficult to get off as you need a special puller. A shop should charge about 1.5 hours for this job. It is a very common problem.

Best to do a fuel pressure test, pump might be weak and dosent show up until it gets gets warm. Best to do the test after it quits again when pump is at its hottest. If you havent done it yet chg. fuel filter too.
