Question about 1994 Cadillac Seville

1 Answer

Dash Lights Out

This problem is concerning a '94 Cadillac Seville. The lights in the dash display for speedometer, RPM meter, and other indication lights have stopped working, but light dimly when the brakes in the vehicle are pressed. I believe with a wiring diagram the location of the problem could be found, but I would appreciate it if you could narrow down the possible areas in which this may have occurred.

I need to know what controls the lights that illuminate the radio and heater controls on a 1998 Cadillac Seville. the displays are working. Just not the buttons on each are not lit

head light switch make sure you don't have the instrument panel dimmed all the way down if so turn it up, then if that doesnt work make sure your head lights are turning on when they are suposed to, if not you may have a bad light sensor on the dash or bad headlamp switch.

when i see the dash lights go out i think of the headlight switch and the dimmer that they usually have. Pull off the headlight switch and look for overheating, melted insulators on the wires.

No dash lights when headlights are turned on. Everything works fine on my vehicle EXCEPT today the panel lights don't work. Turn signals, hazard blinker, oil gauge, rpm gauge, speedometer, drive shift...

there is a regulator for the display brightness, you may have it turn'd down or it has stopped working;. it controls the brightness at which the dash lights are. usually has a speedo sign on it. goes up and down. it works with the main light and is conecter to them on the same lighting board if it has gone then a new light swtch control switch will be needed.

I have a 92 Seville and the problem is with the Dash section of the car. The speedometer and Tach work along with all the high beem turn signals restraint lights, but the Milage does not display, nor does...

The backlight bulbs are burnt out. Common on this model. Unfortunately, it is NOT an easy fix. You'll need to pull the dash cluster and replace the bulbs. It involves de-soldering the old bulbs and replacing with new. I have done this but it is very time consuming and you MIGHT damage the circuit board if you are not adept at micro-soldering. IF you do this, replace ALL the bulbs as others will slowly burn out. Replacement bulbs are NOT available thru GM. You'll need to go to a place like MCM Electronics or Top Bulb to get the correct one....There are businesses on-line that specialize in dash repair. GOOGLE to find them.. They ususally charge $100 for this service.

My dash lights don't work all the time.

Theres not much u can do without the wiring diagrams, tools & knowhow on an intermittent electronic problem. I suggest u "bite the bullet" get it done properly. Theres a motherboard behind the dash that u have no way of checking on your own. Good luck
