Question about 1994 Buick LeSabre

2 Answers

My 1995 Buick LeSabre has an elecrical problem. The car may run fine. Then after stopping it for a while and trying to start it, the dashboard warning lights come on dimly and there is not enough electricty to turn the starter. There is a low-level grinding sound that can be heard from under the dashboard or in the glove compartment area. It seems as though the battery is out of juice. However, later, I can turn the key and the car starts immediately. When the car is in it's no or low electricty mode, sometimes the domelight will not come on inside the car, and the dashboard lights are all off; but the electronic clock on the radio works. Also, I have had a problem with the elcetricity cutting off suddenly while driving the car in the past. A mechanic replaced the ignition switch, and the cable from the battery to above the relay/fuse boxes under the hood has also been replaced in the last 3 months. This elecetrical problem seems to be a new one. Any ideas on the problem?

My 93 did the exact same thing ,Clean under the red plastic cover on the positive Battery cable at the Battery. Disconect it from the Battery and peel the red plastic back and with a wire brush and a scraper get all the white powder out.You can't see it untill you pull it apart. I have to do it about once a year. Hope this is your problem. A cheap fix.

First I would disconnect and clean both ends of the negative cable at battery end and at engine end. This may not solve your problem, however it will eliminate one possiblity and you probably need this done anyhow, most of us don't think about the other end of the ground cable when cleaning them.

My 1995 buick lesabre check engine light is on


Take it to a real mechanic, not the phoney physics at the zone. The speed sensor will not respond if the car is not moving. May be an air flow sensor. They will go bad if it has ever been wet. They can be checked with a scan tool.

1995 Buick Lesabre: security blinks and car will not start


If the starter is turning the engine, try re-setting the security system (leave key on till light stops blinking.) If the starter does not turn, you may have some success in re-setting system, if not you need to check battery voltage and voltages in starter system till you find the problem...can be something as simple as a bad connection at the battery. If you need help with further testing, just ask.
