2009 LC Daytime Running Lights Failure (1 Viewer)

[Monsignor]

Hello all,

About 2.5 years ago I swapped out all lights on my LC for LED. Last week both DRL died at the same time... and only flashed on/off intermittently (think photo flash). The high beams work fine.

I replaced the LED with some halogen bulbs and I got the same result - no DRL but the high beams work.

I replaced the relay in the fuse box thinking that might be the culprit. Still No joy.

Since both died at the same time my thought is that it was either the relay or the DRL module itself and not the resistors?

Before I go down the daytime running light module/resistors path does anyone have any experience with this? Am I missing something?

Thank you in advance!

Isn't there only one resistor, located between the passenger headlight and the PS reservoir?

Seems like easiest test would be checking voltage before and after the resistor with high beams off and engine running.
