Can anyone tell me where the drl module is located on a 2000 Chevy Blazer

Doesn't have DRL module . Has The daytime running lamp (DRL) relay controlled by the BCM .
Daytime Running Lamps (DRL) Relay
In the Underhood Fuse Block
On some earlier production vehicles, the DRL will turn OFF when the turn signal lamps are activated. This is controlled by the BCM and is a normal condition. The daytime running lights operate when the following conditions are present:
• The ignition switch is in the ON position.
• The headlamp switch is in the AUTO or PARK position.
• The park brake is released.
• The automatic transmission is shifted out of the PARK position (if equipped).
• The ambient light sensor senses a daylight condition.
When all conditions are present the body control module (BCM) will turn the daytime running lights ON.

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