2001 Buick Regal GS How to turn off " Low

At this point...replace the entire dash cluster. Either that...or the wiring from the fuse to the dash are gonzo or has a short.

Get this manual online at www.reliable-store.com and get complete guide on whether to repair or not, service it, and how to repair etc, along with wiring diagrams, electrical diagrams, torque specs, error codes, everything.

it is probably just a burnt light on the dash for the a/c and the odometer, as for the low coolant light if the car jhas more than 100,000 miles on it you need to get the coolant flushed that is all the light is warning you about.

The low coolant light is turned on by a sensor in the coolant reservoir when the fluid drops below a certain level. If your reservoir is full, the sensor may be shorted. Assuming the fluid level is good, try taking the connector off the sensor. If that puts the light out, replace the sensor.

I just wrote this for someone else too. If you're a handy person you can fix it yourself for about $12, it worked for me. All you need is a pack of resistors from RadioShack (On the computer chip there is a location that holds the 4-resistors that operate the odometer, they tend to fall off over the years, all you need to do is solder new ones on) and soldering gun. I did it myself and with this video's instruction and it only took me a little under an hour and $12.00. The most daunting part of it is getting the cluster out of the dash.

the sensor wire(s) could be broke

The low coolant sensor should be located in the passenger side radiator tank, You need to take it out and clean the sludge off of it for it to work right. Or you can just unplug it and forget about it, the light will go out and it won't cause any problems.

It is your Instrument cluster, see my answers to this question and write me if you have any more questions, it cost me a total of no more than $15 dollars to fix it myself, took be about one hour.

check one of your coolant sensor's

Replace the coolant level sensor.
