How to change a dash light bulb

That is an easy fix, it is one of two issues.
(1) Check the fuse for the dash lights. If the fuse is ok , it will be (2) burnt out bulbs. For #2 - you have to remove the bezel surrounding the dash cluster. Then look to see if the bulbs are good or have burnt out. The new bulbs are available at almost any auto parts store.

You will have to remove the cluster. Remove the trim around the dash in front of the cluster, remove the bolts holding the cluster in, then you can access the rear to replace the burnt out bulb.

What that rapid turn signal on the dash means is, the rear turn signal tail light is burnt out. This is how you know the bulb is bad. Replace the burnt out tail light bulb and you will be back to normal.

They probably took the bulb out or it is burnt out. I would check the bulb. The dash light is supposed to light every time the car is started. It is called a bulb check.

the fuse is broke

If the blinker light on your dash also flashes rapidly it generally will mean that one of your blinker bulbs is burnt out. Try each direction and check the front and rear bulbs yourself. It is not impossible to have burnt out a bulb on both sides, so check them all carefully. If the lights themselves flash rapidly, or do not flash at all, then yes change out your flasher, which you should be able to get from any local parts store for a reasonable cost.

There are several bulbs in the dash that come on with the headlight switch so it is unlikely that they all burnt out at the same time.I would check the instrument light dimmer switch for power in and out of it before blameing dash bulbs.You should check the plug to the light switch to check for power out of it and to look for burnt wire ends.

Could be a bad flasher.

check fuses

you have one or two bulbs burnt out that can be changed with the dash face removed generally possibly from behind
