How can I see the mileage on my car if the dashboard panel wont light up. What should I do?

If the dashboard mileage light on your 2001 Buick Regal LS is very dim and the Service Vehicle Soon (SVS) light and antilock light stay on, there could be a few potential causes for this issue. Here are some things you can check:

1. Dim dashboard light: If the dashboard mileage light is very dim, it could be due to a burnt-out bulb or a problem with the dimmer switch. Try turning up the brightness using the dimmer switch, and if that doesn't work, check the bulb and replace it if necessary.
2. SVS light and antilock light: The SVS light and antilock light staying on could indicate a problem with the car's computer system or with the antilock brake system. It could be caused by a faulty sensor, a wiring issue, or a problem with the computer itself. It's recommended to have the car's computer system scanned for error codes to determine the root cause of the issue.
3. Battery or charging system: A weak battery or faulty alternator can cause electrical issues in the car, which could be related to the dim dashboard light and the warning lights staying on. Have the battery and charging system checked to rule out this possibility.

This is a common issue with this vehicle. The instrument cluster will need to be removed and either repaired or replaced.
If you replace it with a used replacement, you will not have your original mileage. I would send yours in for repair. Here is a link to a repair facility.

Have someone check fuse under dashboard. Some dashboards have lights wired in series. If one light goes out, they all go out.

Do an online search for speedometer repair places. You can get yours rebuilt for a fraction of the price of new or junkyard

if its on when the brake isn't being depressed its a tail light bulb has blown out, if its on when you apply the brakes , its a brake light bulb

I’m assuming that you are talking about your instrument panel lights.
First, make sure and check the dial on the dashboard to the left of the instrument panel. It controls the brightness of the instrument panel lights. Turn the dial to adjust the brightness. If it accidently got turned all the way down, you will have no instrument lights.
If that isn’t the problem, the interior fuse box is underneath the dashboard on the driver's side. Remove the fuse box lid by swinging the lid down and pulling it straight out of its hinges.
Fuse number 30 (7.5 amp) controls your instrument lights.
Hope this helps you.

i have a 1998 infinity i30t my rear brake lites wont go off when the car is off and parked

Hello scooterr1105,

If you have an all digital dash, then no, there is no light bulb to replace. It is a digital device, such as that of a calculator. While I am not familiar with these types of dashes, there may be some type of element in there that merely needs replaced. My Odemeter (milieage indicator) is lighted as such as well. I haven't had any issues with it as of yet, but I imagine there may be something to replace, rather than the whole part. I would call the manufacturer, or the dealer to research this more.

Most likely this is caused by either the dimmer being turned off (happens all the time on my Corvette) or the dimmer is defective.
