Low Beam Headlights Not Working-2000 Camry

I have replaced the switch, relay under the hood, the fuses are fine and also replaced a headlight bulb all with no luck. I'm stumped as to what it could be. I've read some had success with replacing the integration relay under the dash or maybe a loose ground. Would anyone happen to know where the integration relay is in the pic I posted?

Does the car have daytime running lights, auto light off, etc?

Yes, has daytime running and auto light. The auto light sensor is on passenger side dash by the windshield. I've wondered if the sensor may be causing the issue.

At night when I start the car the day time lights turn on, but turn off when I turn the switch to low beams.

Did you check both high and low beams fuses?

Do the high beams and flash work OK?

Both high/low beam filaments receive 12v power. The headlight circuitry then routes the ground wiring to turn on/off a filament, engage DRL, etc..

High beams work fine and so do the flashers. I've been driving at night with my high beams on for a week now.

I've checked all fuses and they all are fine and also replaced the HEAD relay. I still hear loud clicking coming from the fuse box every time I turn the HL switch on.

Which relay did you replace? There should be a DIM relay that controls the low beams.

Only the HEAD relay as I mentioned above. I didn't know there was more than 1 relay that controlled the lowbeams. So when I went to the junk yard I only grabbed the head. I'm hearing a loud clicking noise when I turn the switch on to the lowbeams. I'm probably going to make another trip to the junk yard this week to grab a integration and DIM relay. I posted a pic of the relay I replaced.

Relays are Headlight, DRL No 2 and 4 and DIM.

Try to narrow down the area of the click.
