Can't Get My Headlights To Turn On Options

[dr4goncl5ws]

Hey guys,

I have a 1999 Celica GT. I can't get the headlights to turn on when I flip the switch on the light stock.

Here's what I know or have tried:

• Replaced headlight relay
• Replaced integrated relay
• Checked headlight fuses
• Checked main 60A fuse
• Checked the ground on the left side of front bumper
• Replaced headlight switch
• The turn signals work
• I can flash my high beams
• The headlights come on when I jump the connectors at the relay with some copper wire
• My bulbs are fine

Does anyone have any other things I can check/replace? I've run out of things to check that aren't in the wiring harness.

Thanks to anyone who can provide some insight!
