Question about 2000 Chevrolet Astro

1 Answer

2000 Astro van. When the light sensor turns the running lights up to full lights at dusk the headlights come up but the taillights (and most of the dashlights including the clock) turn off completely. The brake lights and turn signals still work. Turning the lights on by the switch does not override the problem. When started after dark everthing works the way it should until you shift out of park and then off go the lights. It must be a bad switch connected to the light sensor but I have no idea where it might be. Any help would sure be appreciated. Frank

It can be faulty Ambient light sensor or there is a short in the wiring's causing this.It needs proper diagram and troubleshooting to locate the fault.The exact wire with color codes needs to be traced. Press the "Dome Override" button 3 or 4 times within 6 seconds. This will disable the DRLs while the vehicle is running. When it is restarted, the DRL function will reset to "always on." ---------- Please click this link below and follow the procedure.Its a complete diagram and procedure to troubleshoot the problem:---- ------------- This should help.thanks.Helpmech.

2005 Astro van Head lights - How can I modify factory setting to turn off headlights when car is running?

Try pulling the fuse or the relay marked DRL (Daytime Running Lamps). More than likely each headlamp has its own fuse and relay.

Also, ensure that your headlamps work when you turn on the switch!

All exterior lights are on when engine is started and wont turn off until engine is off, could it be the switch itself?

Is this happening all the time or just at night? The car is equipped with automatic daytime running lights which automatically turns on the full lighting system at dusk and off at dawn or other lowered daylight situations. Do you have something on the dashboard covering the daytime running light sensor? Is the headlight switch turned to the off position?

Yep, If you want them to turn off. Turn the ignition swich to the on position and press your emergency brake in. Your headlights should shut off. It is a feature GM has called DRL's daytime running lights.

Head lights not working

Check your operators manual. When the daylight running lights are on you can't turn on your high beams. The car has two circuits. Remember to turn your main headlights on at dusk because your taillights are not on with your day running lights and someone can rear end you. You have to fully turn on your headlights in order to get access to your highbeams. Good luck!
