Click the search button then the blue links . Looking at the wiring diagram i see the DRL relay is located in the BJB - this is the fuse / relay box in the engine compartment . To see location under system click on electrical distribution ,then on junction block . picture of fuse box shows location .

Behind the lower kick panel on the passenger's side good luck colin

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 .

DADRL - How To Disable DRLs

There is no DRL relay , has a lamp control module .
The daytime running lamps (DRL) activate under the following conditions:
?€¢
The ignition switch is in the RUN position.

?€¢
The ambient light sensor indicates daylight.

?€¢
The vehicle is not in the PARK position.

When the above conditions are met, the lamp control module (LCM) supplies battery positive voltage (B+) to the low beam headlamps through CKT 589 (GRY), the DRL resistor, and CKT 12 (TAN). The DRL resistor reduces the voltage supplied by the LCM. The low beam headlamps light at a reduced intensity. The DRL disable if the vehicle is placed in the PARK position. When the ambient light sensor indicates darkness, the low beam headlamps automatically switch from a reduced intensity to a regular intensity.

Headlamps Inoperative - Low Beams

Step

Action

Value(s)

Yes

No

DEFINITION: This diagnostic procedure should only be used if the high beam headlamps are operating properly and the low beams are inoperative.

1. Turn the headlamp and panel dimmer switch to the ON position.
2. Move the headlamp dimmer switch to the LOW position.
3. Backprobe the headlamp dimmer switch connector with a J 35616-200 from cavity A to ground.

It in the rear of the glove box.There is a cover that says relay center, remove it and its the relay to the far right.

this sounds like the daytime running lights relay is no good and needs replacing.they are put in different locations so you will have to ask a shop were its located.

follow the wires to the drl relay. It must be inline from the regular light switch to the headlamps. I have a 1990 Cadillac Deville that has an aftermarket module that controls the daytime running lamps, and it is mounted on the driver's side wheel well.

Some relays are found in the fuse box under the hood.

If your daytime running lamps burnt out, take it to an electrical shop and ask them to check it out.

If you buy an aftermarket daytime running lamp kit, they can install it for you.

But, I agree, you should check for voltage and function at the relay for the daytime running lamps on your Astro.

But, if all else fails, the electrical shop should be able to diagnose and repair this problem.

are your daytime running lamps working. if they are according to the schematic there are 4 relays, fog lamp, fog lamp cut off, isolation, and daytime running lamp; 2 fuses: right and left, that supply volts to the headlamps. it's a little confusing though, because these schematics might have some mistakes. anyway, it looks like the drl relay.grounds the headlamps when the drl control in the micro processor located in the instrument cluster senses the headlamps have been turned on. this trips the relay and 12vdc is supplied. the dlr might be bad. otherwise, i would think you have a hardwire or connector problem.
