Question 1997 chevy suburban daytime running lights

i have a 1997 chevy suburban. the daytime running lights are not working, even though the green indicator light is on. also when the high beams are turned on, the low beams turn off, so instead of all 4 lights being on, only the inner high beams are on. the low beams work fine on their own however. i have replaced the drl-module, but no change. i suspect the drl-relay, am i on the right track? also i can find no reference in any manual as to where this relay is located. the wiring diagram and owners manual show it exists. the owners manual says its in the fuse/relay block under the hood, by the master cylinder, however the only thing there is a fuse for fog lights. the drl lights did work before, and i have changed nothing under hood to cause this. they started working again for about a week, but then quit again. any ideas or input will be greatly appreciated.

I assume you have checked the bulbs???
The Chevy headlights work that way, only one set lit at a time. There are kits available to change it so both are on with high beams.

Thanks 1rooster, i did make sure the emerg. brake is all the way off. Also since my last post, i found the drl-relay, and tried a new one....still doesnt cure the problem. I'm still studying the wiring diagrams to see if maybe the drl's are routed through the dimmer switch, or the headlight switch. If any more ideas or input, i would appreciate it.

They do not light when the trans is in park. Is that when you are checking them???

hi just bill, i've checked them in all phases, park, drive, reverse, motor running, and not running. When they were working, they would come on just by having the ignition switch turned on, even without the motor running, and in park. I'm going to go over the wires again, just to make sure there are no loose or disconnected connectors or plugs. Maybe it will be something that simple.....doubtfull according to murphy's law though...

My 00, and the new 07, are both the same, no DRL in park. But you have obviously checked that.
