Question about Chevrolet 1500
Check to see if you have a high current fuse and relay box under the hood. Your owner manual should tell you where the fuses & relays are.

It sounds like the high and low switch has gone bad or the relay's to your high or low beams. If my memory serve me right the DRL and low beam relay is located on driver side under the hood you will have to open up that black box to get in there. i try to recall there is at least 3 or 4 relay almost all are look the same but function is different. i know there is a relay used for headlight circuit. due i work on the truck similar year due i have to hook up plow lights. Make sure beam indicator is on low beam.
The five term. to relay hear is what you should read
Light green/Tan ground
Do you hear relay click when placed into term?
Also on left side there is the DRL control module has about 11 wires to it this maybe the fault. There is also relays under the dash on the drivers side, it may be there, just having a brain freeze right now in Chicago. >>drive a tour bus also and on tour right now. Keep me posted be glad to get your lights working again, but there is a headlight relay i do know that, just can not remember where it is. Sorry for the memory lost friend. Have time before i move again. I'm staring at the schematic for a 98 headlight circuit. The feed for both the hi and low beam comes through the DRL module. The factory manual states it is taped to a wiring harness under the left side of the inst panel. I would give it a good sniff test before wasting money on a new one. There is also a protective diode (203) in series with this feed before the DRL relay. It is part of the wiring harness "at RH of steering column support". I have not got a clue what it might look like. Probably a small plastic enclosure similar to one of those add-on fuse holders. It should be cheap.
The DRL module supplies ground signals for the DRL relay and the green DRL dash light. You still need to check for power coming out of the lite sw to the DRL module and to the dimmer sw, all on the yellow wire. Check the "LIGHTING" 50a fuse #8 in the under hood fuse block. Check for power on the yellow wire at the dimmer switch with the head lights on. Diode 203 is in-line with the DRL power feed from the DRL-FOG fuse in the I/P fuse block for the DRL's only and has nothing to do with the headlights working when the headlights are turned on. Oh and there is no relay i can find on this CD for the 98 but should be similar to your 95 since there in the same years of production group. Good luck a sorry if i'm a bit confusing, darn tourist. LOL
