My digital dashboard wont turn on. 97cadillac deville

If all the lights on your dash seem to be off, the problem could be a bad fuse.

Locate the knob por dial that control the brightness of dashboard light.

Make sure the brightness control is turned on. If it is and the lights aren't working, the problemas may be a bad fuse.

Use your car manual and locate the dash fuse the fuse box is between under the steering wheel and the door. Pull out the fuse and use a test light by connecting the groud clamp to the metal and placing the other end where the fuse was. If the light come on, you need to replace the fuse.

Here you go

blower is under dash in r/f

I am taking a wild guess that your car is old enough to have a turn signal flasher.
It should be under the dashboard where it is almost impossible to see! Here's how to find it:
Find a good flashlight and a little tiny person. :-)
Turn on your 4-way flashers, and look up under the dashboard, to the left of your speedometer. (See why I said a small person?)
The 4-way flasher should be clicking.
Look at the shape and size of that flasher that is making the clicking sound, and you should see another one close to it just like it that is not making any noise.
That should be your regular turn signal flasher, it's probably be ready for a new one.
Usually they plug in.

I'M HAVING THE SAME PROBLEM WITH A 96 DEVILLE. NO SOLUTION YET. DOES YOUR CAR START

You do not need to remove the battery to charge the battery. When you connect the charger you MUST be careful to connect the charger's positive lead to the positive terminal to the battery and the negative lead to the negative lead to the battery before you turn on the battery charger. Connecting the charger leads the wrong way around most likely damage the vehicle's electronics.
When you finish charging the battery turn off the charger before you disconnect the charger leads. This will prevent arcing between the leads and the battery.

Dead battery

I HAVE A 1998 CADILLAC DEVILLE,THE AC BLOWER MOTOR GETS HOT AND TURN OFF AND WONT TURN BACK ON UNTIL IT COOL OFF, WHAT IS THIS PROBLEM?

Under the dashboard, near the top of the brake pedal on the back side, there is a switch, disconnect the wire, if the brake lights go out, the switch is bad, need to replace it.
