the left of the steering column:
1) Low-beam cut relay
2) DRL Relay
3) DRL Control Unit (bigger than the others)
Are your DRLs no longer working? That's usually the low-beam cut relay.
Look for a relay with the wires RED/BLK, RED/YEL, RED/WHT, RED/BLU. It's
joined together with the DRL relay, which is the same size but has
different wire colors.
There are input tests you can do to the relays to confirm functionality.
