Buick - LeSabre :: 1996 - Lack Of Brake Pressure
Jan 23, 2013
In Oct. my wife took the car 40 miles from home, lost the brakes, and limped into a gas station. The guy there gave her a bottle of brake fluid and some stop leak. He suggested equal amounts of both and limp back home. She drove back and went to the machanic in town. He wanted $365 to replace all of the brake lines. He said there may be brake pressure problems and he will address them later. Recently I loaned my son the car so that he could deliver newspapers.
After 2 weeks we needed new front brakes. I had brake pressure problems. If the brake pedal did not feel spongy then the brakes felt inconsistent-sometimes high and sometimes down to the floor. There was a sticky passenger front caliper that was replaced. The brakes were bleed and are still spongy and inconsistent. I noticed that the reservoir cap is not good. Could the cap be the cause of the sponginess? There are no leaks around the master cylinder and there are no leaks. Should I replace the master cylinder? 1996 Buick LeSabre 3.8L....

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?

1996 Buick Le Sabre. About 1 time in 10, the car will not start. The starter is fine; seems to get no gas. Took it to garage for diagnosis. They could find NO problem: but replaced plugs and wires anyhow. Car still refuses to start -- just about 1 time in 10. It seems to have a bigger problem if the car was parked going UPHILL. This is not always the case. Is it likely to be the fuel pump? Is there no way to check this without simply replacing the fuel pump?

1996 Buick LeSabre 3.8L... Under the pcv valve housing is a short plastic 90 deg. elbow, about 3/4inch wide. The elbow looks like it comes from the upper plenum and goes into a metal housing behind the belt tensioner. This elbow leaks from behind the belt tensioner side. My question: what is this elbow called? How do I fix it?

I have a 1996 Buick Le Sabre. There is a bad water leak onto the passenger side back floorboard. I have taken it to the dealer and two repair shops. They are stumped. A hard Florida rain can get 2 inches of water on the floor. Tried re-gluing the rubber seal. That did not work.

I seem to lose power steering pressure when I hold the wheel in a turn. It is only temporary as it cycles until I release the turn. I happens turning in both directions and a any speed. I have replaced the struts and strut mounts and have rotated the tires. The power steering fluid quantity is good with no leaks.1995 Buick Lesabre.

The light has been coming on for the last couple of weeks. I can reset the light by pushing the dash button. On a 700 mile trip last weekend, I probably reset it half a dozen times. The tires are all at 30 PSIg. Two tire gauges agree. I don't know how the system works. I don't think there is a sensor in each wheel like some later cars have. I suspect it works off of ABS sensors and wheel revolutions. The ABS light is not on, nor has it been.
The right rear tire has been replaced with one of the same size, but a different brand. This issue started a month after that. Can that tire have a different revolution length per rotation and cause this issue?

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 brake pedal needs to be practically be pushed to the floor for the car to stop. I went to a Munro Muffler and they replaced all brake pads and turned the rotors. The problem of the pedal to the floor did not go away. The Munro tech struggled with this then popped me with this estimate - brake lines master cylinder to ABS / brake lines ABS to front brake flex hoses connections, / brake lines - ABS to rear junctions fittings at the passenger front door. Also they want to sell me a rear wheel bearing because the temperature at one point was very high. The total estimate is $840. I can remove the Rear wheel bearing to bring the estimate down to 500. I asked if we could do lines from ABS to Master Cylinder only and the tech advised against it. I feel like I am about to get ripped off and am going for a second opinion.

I have a 2000 Buick Lesabre with 226k and my parking/E-brake annoys me. The brake isn't stuck or anything, but the pedal doesn't come back all the way, at least not enough to turn off the brake light or accompanying dinging. Most of the time, the cable is disconnected from the pedal to keep the light and dinging off unless I have to use it. Is there any way to adjust the parking brake to get the pedal to fully return or is there something else wrong with the system?

I have a 1996 Buick Century that I started having problems with tonight.
As I was driving, I pressed the brake pedal down and it felt like I lost most if not all of the pressure in the brake system and it was a bit difficult to come to a complete stop for the rest of the trip.
I admit that the system hasn't been maintained in quite some time, but I recently filled up the brake fluid reservoir (2-3 weeks ago) after the brake dashboard light came on and the brakes worked just fine after this.
What is wrong with my car, and how do I fix it as cheaply as possible (or is it a cheap fix?)?

The front motor mounts are bad. This has been confirmed. When I am cruising at a constant 45 or 55 mph and choose to accelerate because traffic is clearing, etc. the car will thump a bit and only slowly creep faster. It feels as if there is very little response other than the mild thumping. Getting to 65 mph takes time. The car has 70k miles and performs almost flawlessly at slower speeds. Is the thumping/lack of acceleration a symptom of the bad front motor mounts?

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.

I have a 95 Buick Regal, V6 3.8 Liter. The symptoms are the following: stuttering idle. And lack of response at times when I try to accelerate. Like sometimes I'll be driving on the highway, and having no problems. Then I'll be going up a hill at around 55 mph, and then the car will shudder as I try to maintain a speed of 55 mph. So I have to ease off the accelerator and slow down. At first I thought this was a transmission problem, but I am guessing it's the same problem that causes my choppy idle.
So I had this acceleration problem on the highway when I was going up a hill. And a weak idle. These problems have been going on for several months now. They were annoying, but didn't seem that serious. Then all of a sudden, on a rainy day, the car was really responding poorly to acceleration at all speeds. I was able to drive around, but I couldn't count on the car responding right away when I hit the gas pedal. And the car would shudder at times. Then, I didn't drive the car for a few days, and then it was dry, no rain, and the car ran better. So I am thinking humidity makes the problem worse.
I have also noticed over the past few months, that the car runs best when I start it up after a few days of not running it. Then if I drive the car a few miles and let it sit for about 2 hours or so, it would idle weakly when I would start it up again. The car's been doing that for several months now, but it wasn't really affecting the drivability or the response of the car when I hit the gas pedal.
Now it's gotten much worse. So, I've already replaced the following items myself to no avail: mass air flow sensor, oxygen sensor, and egr valve. I am guessing the next thing to fix is the pcv valve. But I also think it might be the fuel pump. My first guess though is the pcv valve. What else could it be? And is there any easy way to test to see if the fuel pump is going bad? Or should I just take out the pcv valve and see if it looks bad?

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.

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.

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.

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.'.

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...
