I have a 1996 chevy blazer 2 door 4.3 Vortec. My day time running lights don't turn on anymore and my dash light for them isn't on anymore. When i turn my lights on, they flicker, relay clicks fast, and voltage drops. My high beams work fine though. (sealed beam type headlights) The only way i can drive at night is to put my headlights on, turn my highbeams on, then turn my headlights back off but keep my headlights on. This gives me my right headlight on normal, and the left one is about half the normal lgiht output. I don't know if there is somekind of module i can replace or where it may be located. I changed the relays in the dash and that didn't fix it. Please Help! Thanks.[/align]

 

Sounds like it might be a bad DRL relay. In my 99 it was in a fuse and relay panel under the hood on the driver's side next to the air filter. Your owner's manual will show you which relay controls the DRLs.

 

Thanks for the response. I have checked the fuses and the relays in the glove compartment, all check out fine. I know under the glove box, if you remove a panel where the passengers feet would be, that there are a few wiring harnesses and modules. I did here a clicking coming from in there before, but i do not know what they are. Also i had a water leak in that compartment and water might have gotten on those modules/harnesses, but like i said, i don't know what they are.

 

The relay may not be in the glove box area - check your owner's manual, or perhaps the owner of a '96 will chime in and tell you the location. The relay on my '99 is a classic 1" black cube with 5 (I think) tabs sticking out.
