Do I need to reprogram or code this headlight after installation?

No reprogramming required — this assembly connects to your factory harness and operates as a direct replacement. Plug it in and you're done.

Will this fit if my original headlight has water damage or condensation?

Yes, this is a complete assembly replacement, so it bypasses any existing damage in your old unit. Just remove the old headlight and install this one in its place.

What if the DRL doesn't work after I install it?

Check that the connector is fully seated in the wiring harness and that all power connections are tight. If the low or high beam works but DRL doesn't, verify your vehicle's DRL settings in the gauge cluster menu.
