Dash and tail lights go off at night.

Ok first your tail lighs work of a fues with a test light you can buy cheap at dollar store test all the fuese on the fuese box 1 under the hood the other under the dash under the steering wheel or on the side of the dash board if all fuese r good at night with the lights on check if you have dash light on your instrument panel if no light you have a burn fuse also the tail light work of your headlight switch the only way to check if it's your switch is to remove it n bypass with one wire you'll have a big red wire the will be your 12 volts stick it on that the the other side stick it on the yellow or brown wire if your tail light work u have a bad headlight switch but don't touch any black wire those r growing you'll just burn the fuse those r easy to replace good luck hope I was helpful

Check the fuses against a dark piece of paper. I have had some look OK but looking closer against a dark background showed a crack. I had a Toyota that thought it didn't have any gas and would run intermittently. Checked all sorts of things and it was a 15 cent fuse.

check the light control module for operation

Without testing i would say you have DRL control module problem , But that would just be a guess .
In the night mode, the DRL ambient light sensor senses darkness. Then, the DRL module turns off the front turn lamps and turns on the headlamps through circuit 10. The DRL module also turns on the park, side marker, license, and tail lamps. If the engine should stall with the DRL control module in the night mode, the DRL control module will turn off the headlamps and leave the side marker, park, license and tail lamps on while the engine is being cranked. The headlamp switch operates as usual.
The Daytime Running Lamps (DRL) control module is designed to automatically operate exterior lights depending on outside light conditions. The DRL control module operates in two modes, the day mode and the night mode. In the day mode, the DRL ambient light sensor senses daylight. Then, the DRL control module turns on the front turn lamps (non-flashing) if under the following conditions:
• The ignition switch is on.
• The headlamps switch is in the OFF position.
• The park brake is released.

The brightness of the Vacuum Fluorescent (VF) displays is controlled by two signals: the park lamps on signal (circuit 230) and the VF dimming signal (circuit 308). With the park lamps on, the VF display of the radio, heater, A/C control (with RPO CJ2) and the instrument cluster will dim for nighttime viewing. When the park lamps on signal is not present (park lamps off), the VF displays are at high brightness for daytime viewing. When the park lamps are on, the I/P lamp dimmer switch provides a signal (VF Dimming Signal circuit 308) which controls the brightness of the VF displays when the I/P lamp dimmer switch is adjusted.

Do the Daytime running light's work ?

Failed Battery is where I would start my testing

what happens when you turn the knob to brite/dim the dash lights?

You have a light sensor that automatically turns on your lights when it is dark enough. This is not your daytime running lights. It also turns on the dash & tail lights. This is why they do not get brighter when you turn the switch on, they are already on. If they do not seem to be bright enough, you may need to adjust the headlight aim.

Check and make sure your tail lights work, Check your fuses!

Look for a bad fuse. All the cars that I have owned had both the tail lights and dash lights on the same fuse.

DRL (Daytime Running Lights) will come on any time you start your car.
The dash lights do not come on, unless your headlights turn on. Either by a daylight sensor or if you manually turn them on by the switch.
So even though your headlights are on with the DRL, if you notice the tail lights do not come on (just like the dash lights don't).

To test if your dash lights do work, turn your headlight switch on. You should the the tail lights and dash lights come on.
