Buick - LeSabre :: 2004 - ICM And Coil Failure

I have come to understand that Buick LeSabres are known for their issues with their ignition modules but I'm trying to figure out the root to the problem. I have an '04 LeSabre 'Custom'. I have had all of the coils and wires replaced and the ignition module. I had to replace some of the coils and ignition module twice since. I can already feel it going again.

Buick - LeSabre :: 2004 - Hesitates While Shifting Between Gears?

Our 2004 LeSabre has the following symptoms - there's a clicking that occurs whenever the car is in motion, the car occasionally hesitates/bucks when shifting between gears (but not always), the radio sometimes does not go off when the keys are taken out of the ignition, we're losing about a quart of oil about every 2500 miles but there is no sign of a leak on the ground, we also seem to have reduced mileage (using more gas).

In this corner, Mechanic 1 (high price) - replace front lower control arms, sway bar, and bushing, front end alignment, throttle body gasket and EGR tube, oil pan gasket replacement, ignition switch replacement, brake fluid and coolant flush. $1900

In the other corner, Mechanic 2 (low price) thinks it's just the spark plugs and wires that need to be replaced, the wires, replace air and fuel filter, and PCV valve - $450

We had the oil changed about 2500 miles ago, replaced the air filter then. The oil change place suggested a coolant and brake fluid flush. I've used mechanic 1 in the past and they have replaced my head gaskets a couple of times and I suspect they are ripping me off.

Buick - Lesabre :: 2004 - Right Signal Light Blew Out Along With Low Beam

I have a 2004 buick lesabre that last year had the steering wheel harness replaced (left blinker issues and then just total car dying while driving). This year, the right signal light blew out, along with the low beam light. When I replaced them, the low beam light was very faint, and the signal light worked (till the next morning for the low beam light and till I closed the hood). So fiddled with the signal light, it works- but now the right signal blinker works but not the marker light and still can not get the low beam to work again.

Buick - Lesabre :: Stalls Out When Get Up To About 20 Mph

I have recently noticed that my car will stall out when I get up to about 20 mph. My car starts fine, no check engine light on. I has a tendency to just die in the middle of the road at times too. I have changed the spark plugs, spark plug wires, and a new fuel filter. Do I need to change the mass air flow sensor? Or the crank position sensor? I have no problems starting the car either. Runs good when it runs.

LeSabre :: 96 Buick Periodically Stalling / Relays Getting Hot

1996 buick lesabre custom 3800. The car stalls from time to time, and the fuel pump, power windows, power seats, and power mirrors all stop working. Most people who have had this problem cleaned the ground bus on the drivers side under the carpet. I have done this, and the car has not stalled yet, but I haven't driven it far because I have noticed the fuel pump relay and power windows relay are getting extremely hot to the touch after 5 minutes or so of driving. Why these relays are getting so hot? I cannot afford to keep getting the car towed home.

LeSabre :: 2001 - Buick Losing Coolant

My 2001 Buick Lesabre has always shown to run exactly normal on the temperature dash unit until recently. I checked my coolant level and it was a bit low, so I added. After I filled the radiator I have noticed a coolant leak spot on my driveway, after I drive it now. I have removed the gravel shield and have tried to pin point exactly where the leak is coming from, but cannot. Now, each time I park, after driving it, I put a clean piece of cardboard under it to try to see exactly what area the leak is coming from. Last night I put the car on ramps and crawled under to discover that the leak is located just above the oil filter and is actually dripping from the oil filter, but I still cannot see the exact location of the leak.Actually the leak does not appear until about an hour after I park the car, so it sounds like something is contracting after the engine has cooled off, but what? The leak has seemed to be getting worse each time I drive the car. How can I determine exactly where the leak is coming from without just changing a bunch of parts.

LeSabre :: Buick - Brake Fluid Keeps Leaking Out

I currently have no brake fluid in my car because it keeps leaking out (leaks while actively being used). The leak is between the power brake booster and the brake master cylinder... Is there any type of gasket I can get to better fill the gap between the two pieces of metal? Is there some way to tell which of the two pieces is creating the leak to narrow down which to purchase?

My car would not start yesterday, and I realized the fuel pump was not running. So I bought a new fuel pump today and put it on, the car still won't start, the fuel pump still does not run and I have been told to check the relay. I cannot find the relay for this car.

Buick - Lesabre :: 1998 - AC Sometimes Stop Blowing

My '98 Buick's AC works well when I take it to a mechanic. But when I leave after they say, 'it seems fine now,' a few miles later the cold air starts blowing through the defroster vents, still nice and cold. Then it comes back down to the dash and then goes back up to the defrost. But sometimes it stops blowing altogether, it doesn't blow anywhere! Nothing, not even warm air. And then later everything is fine again, until it happens all over again and I take it to another shop when I hear 'it seems fine now.'.

Buick - Lesabre :: 2000 Shimmy While Accelerating Between 45 And 50 Mph

I have been to a few different repair shops for my 2000 Buick Le Sabre shimmy problem with no luck. I have a really bad shimmy, while accelerating between 45 and 50 mph, and it seems worse on an upgrade. Past 50 mph, it smooths out. Over the past several months, mechanics have checked the balance of my tires and rotated them, done front end alignment, rear alignment, replaced the right lower control arm, the right sway bar link and the right wheel hub. Still no luck, so it came down to the determination that it must be a bad tire. Now I have 4 new tires (it was soon time to get them anyway), and I still have the shimmy. What else can we look for? My local mechanics seems stumped. I have not taken it to a Buick dealership, however...

Buick - Lesabre :: 2002 - Won't Start After Overheating

I have a 2002 Buick LeSabre. Back information is this. the car has had a coolant leak for years, very slow though. Last night while working (I drive for a living) the thermostat climbed up to hot and then immediately went back down to the middle range where it normally goes, so I thought I was fine. It then climbed back up and staled out. It started again nearly immediately and I made it back to my work. About 30 minutes later I began to drive home. The temperature gauge started to climb up again, and then immediately went back to normal running temperature. I kept an eye on it.

About 2 minutes later it shut off completely. I had dash lights, head lights, and emergency flashers. Trying to restart it killed my battery and I had it towed home. This morning I put water in it (it was a gallon low even though I had filled it three days prior). I got a jump start but the car wouldn't start. It cranked and cranked but would not start. I did notice a leak of water from near the bottom of the engine. I am curious as to what the problem may be and why it is not starting now.

Buick - Lesabre :: 1996 - HVAC Fan Will Not Shut Off

My son's car overheated yesterday due to a sudden crack in the radiator. He had it towed to me. There was no evidence of a blown head gasket or cracked block, so I replaced the radiator. Since the battery was dead, I put the charger on it. When I did that, the heater/AC fan began to blow. The only way I could get it to stop was to disconnect the battery. Even the ignition switch had no bearing on the fan.

I do not know if the overheating and this problem are related. It may be just a coincidence, but it is odd.

This car has a slide to regulate the blower speed. It is not one of those "Select a temp" automatic ones. It will blow cold air out the AC vents when AC is selected, but when the OFF button is selected ambient air goes to the DEFROST vents.

I suspect a relay is stuck, but what relay, and where is it located?

Buick - Lesabre :: 1995 - Shaking At Low Speeds

I have a 1995 Buick LeSabre with just over 100,000 miles on it. Recently it has begun to shake at low speeds. The car shakes as if it were driving over a rough gravel road, and makes a sort of chugging noise when I step on the accelerator at speeds from 15-25 miles per hour. When I accelerate beyond 25, the shaking stops, and the car stops making the chugging noise as well. It drives beautifully on the interstate, but horribly when I am in town. After taking the car for a drive on the interstate for about 30 minutes one day, the shaking at low speeds actually ceased for over a week, but then came back. The "check engine" light has not come on. I maintain the car regularly, getting oil and filters changed, fluids filled, etc. I'm wondering if this sounds like it could be caused by a problem I can fix myself, or if I need to have the car looked at by a professional.

Buick - LeSabre :: 2003 - Keeps Dying Intermittently?

My friend has a 2003 Buick LeSabre 3800 with approximately 80000 miles. He complains that the car will die while he is driving. I work at a local parts store and have access to code reading scanner. We've checked the fuel pressure at fuel rail several times and is okay. The only thing that seems odd to me is that he says the tach will quit working. It dies like the switch has been cut off. He can wait, sometimes 10 to 30 minutes, and the car will restart. I had him to come by work when the car acted up so I could scan it. It gave crank sensor out of range, and indeed the tach was not working. I turned the car off to scan, and restarted. The tach was working.
