No high beams

Curious if anyone had ideas on what could cause this. I recently bought an 08 LE in which everything works except the high beams.

When I pull back or push forward on the headlight control, I see the blue high beam light appear on the instrument panel but the actual bulb doesn't turn on. The low beams and turn signals work fine. I don't have DRL lights as best I can tell. There's no "auto" DRL toggle on the headlight control & the #2,#3,#4 DRL relays in the under hood fuse box are empty (hope that normal?)

No luck after replacing the bulbs and the fuses look ok. I heard the emergency parking brake might affect this, but when I push it on/off, it didn't turn the high beams on.

I've tackled some DIY repair (exhaust, radiator) before but haven't troubleshot anything electrical before. Some tips would be greatly appreciated!

Looks that high beam doesn't work without DRL relays (at least No. 2, 3 and 4). See the wiring diagram in the file attached. It is from 2005 Sienna Repair manual (the download link is in my signature).
