I just bought an '01 Tundra Access Cab 4x4 5VZ with no DRL.

The previous owner mentioned the low beams weren't working but I quickly realized its something more complicated than a burned out bulb.

Here are the symptoms:
-Low beams do not come on when activated.
-When I activate high beams (via flashing or clicking forward) on the dimmer switch the High Beams AND Low beams come on together.
-The dash high beam bulb does not come on ever.

I checked the continuity of the dimmer switch using the FSM I found online and it appears to be correct.

So far I have determined
-H-LP relay must be working for lights to come on
-Dimmer switch is working (I checked continuity)

Wiring diagram below. Any ideas?
