First off, two days of searching has been done. If I somehow missed something, please point me in the right direction.

I ran into a problem with my DRL's, all of a sudden they do not function. All the lights work, HID, high, and wedge.
While in auto mode the lights will not turn off during the daytime, I believe it to be a bad ambient light sensor or associated fuse/relay. I have yet to go tunnel blasting to see if the cluster brightens and dims.

Please help with the troubleshooting of this gremlin.

Cheers.

 

The sensor is located on the driver's side dash next to the glass. Check to see if it's blocked.

 

Not blocked, clear as day.

 

try checking the fuses.

 

All fuses associated with the lights have been checked. Is there a fuse for the sensor? I looked into the owners manual with no avail.

Is C-Best available for download on the internet? I have an open port ecu cable from my evolution days. I'd like to look at the sensitivity setting. I would like to not go to the dealer on this one.

 

Did you check the 3 relays? 2 are on the driver's fender and the 3rd(main) is by the glove box.

 

I'm in the process of doing the relays now, Thanks guys. Keep the suggestions coming.
