What would cause oil pressure to drop to 0 after replacing oil pressure sensor on 2000 Buick la sabre


Why did you need to change it? Did you have low pressure?
Is the sensor telling the truth? You may have to get a mechanic to rig up a manual gauge to your oil system to ascertain the actual pressure by diagnosis. Is the sensor right for your engine?
Tell us a bit more of the history of your problem.

Service stabilizer light comes on, how do you service it. our buick is a 2002 Buick La Sabre, 4dr.


The message means that a fault has occurred in the system and you need to have it diagnosed by the dealer with a special testing tool called a scanner, it is not some kind of a service like an oil change that is performed on a regular basis, the message is kind of misleading and i get this question often..

Le sabre 1991 ltd handbook air conditioning is not very cold out of the vent


I had the same problem with my LeSabre. I took it to a mechanic and he found nothing wrong. Said it was an old car and things like that go out. I took it to a local ac repair shop. Turns out that the ac needed recharging. Anytime the freon is low, the ac compressor will not engage, to prevent the compressor from burning up. Freon contains oil that lubricates the internal parts of the compressor. Have the system checked to find out if a simple recharge is needed.

Brake drums


There is no opening to access the rear drum adjuster. Grab a good size hammer and hit the outside of the drum directly on the flat part to loosen it up, then just pull it off. Don't be afraid to hit it hard. And remember... Don't hit the lug studs! Hope this helps.
