My lights automatically came on when my van was started, until yesterday. I can turn them on manually but like that they came on automatically. The day before the heater blower stopped working on high. Are these related ? Help !
Check your emergency brake to see if it is released all the way. 1or2 clicks on the brake will make the auto lihgts not come on. Try turning the blower motor on and then tapping on it...makes mine work.

otad doesn't help ---did the trans come out of an 05 astro van s-10 blazer /jimmy s-15 or safari and it your awd because you need to match the rwd with an rwd and a awd with an awd /4wd from above and the unit has to be compatible with the 05
It is located in the underhood fuse/relay box , marked DRL 10 amp fuse ! Also if that is good check the DRL relay in the same fuse/relay box .Your light sensor could also be bad .
The daytime running lamps (DRL) will operate when the ignition switch is in the RUN position, for automatic transmissions (A/T), the gear selector is not in the PARK position, the headlamp switch is in the AUTO position, and for manual transmissions (M/T), the park brake is released. When these conditions have been met and the ambient light sensor indicates daytime conditions, the DRL will illuminate. The ambient light sensor is a light sensitive transistor that varies its voltage signal to the body control module (BCM) in response to changes to the outside (ambient) light level. When the BCM receives this signal it will either turn on the DRL or the headlamps for auto headlamp operation. Any function or condition that turns on the headlights will cancel the daytime running lamps operation. The DRL can be manually turned OFF by depressing the AHL/DRL switch in the headlamp switch
Do you know that on inside of fuse box lid it shows what fuse is what .
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.
i'm not sure if your van may be a diferent year of what you are telling me but acording to my repair manual the head light switch for 1999 chevrolet astro is at lt side of dash,
