Where is the DRL module located on a 2003 GMC Savana 1500?

There is no DRL module .
Daytime Running Lamps (DRL)
The DRL are a function of the front turn signal lamps. The DRL will operate when the ignition switch is in the RUN position, the gear selector is not in the PARK position, and the headlamp switch is in the OFF position. When the BCM receives these signals it will signal the turn/hazard flasher module to turn on the DRL by grounding the DRL low control signal. The turn/hazard flasher module supplies voltage to the DRL on the right and left DRL/turn supply voltage circuits. If a front turn signal lamp is inoperative the DRL will not operate.
The DRL can be deactivated by turning the headlamp switch to the DRL OFF position while the DRL are operating. The DRL defeat position of the headlamp switch is a momentary ground signal to the BCM to command the DRL function ON or OFF. After each key cycle the BCM will default to the DRL ON function.

Oldsmobile Cutlass Ciera S 1994 headlights are staying on when switch is off. Took switch out and still headlights are on. Thinking it might be a relay. Need location of it, if so the problem.

Is it high beam or low beams that are on? Do you have drl? Can't rule out problem with drl module? The headlamp switch has an internal circuit breaker, no relay. The diagram is part of headlamps/drl.

Where is the module for the day time running lights on a dodge ram B 1500? 1996

On Canadian vehicles, the low-beam headlamps operate when the ignition switch is in the RUN position and the headlamp switch is OFF.

When the ignition switch is in the START or RUN position, circuit A1 from fuse 15 in the Power Distribution Center (PDC) connects to circuit A21. Circuit A21 powers circuit F18 through fuse 19 in the fuse block. Circuit F18 feeds the Daytime Running Module (DRL) module.

Circuit L20 from the headlamp switch connects to DRL module. Circuit L20 is HOT at all times.

The DRL module receives the vehicle speed sensor input from circuit G7. Circuit G34 from the DRL module provides power for the high beam indicator lamp in the instrument cluster.

Circuit L4 powers the low beams of the headlamps. When the headlamp switch is OFF, the DRL module powers the low beams on circuit L4. When the headlamps are ON, the multi-function switch powers the low beams on circuit L4.

Circuit L3 feeds the high beams of the headlamps. When the operator flashes the headlamps with the stalk of the multi-function switch, the DRL module senses voltage on circuit L3. When it senses voltage on circuit L3, the DRL module stops supplying power to the low beams on circuit L4.

Circuit Z1 provides ground for the DRL module.
