headlight issues

[indulf]

04 yukon denali...

recently my lights were stuck on causing a dead battery.

i replaced the relays (used acdelco units), but i'l still getting some odd issues.

some easy questions:

which is the low beam? which is the high beam? which is supposed to be lit as the DRL?

when running and the headlight switch is in the ON position and lights are on low, i have 4 lamps lit up in the front. when i select the high beams i only have 2 lamps lit up. i'm not sure this is correct.

fog lamps seem to work as designed - only on when selected and headlights are on low. all lamps go off when i turn the ignition off and engage the parking brake.

thoughts?

Go to 1 a auto.com and get a multfunction switch mine did the same thing they will get to where they will not work at all

Daytime running light module, find it and disconnect it. Problem solved. Not sure if that multifunction switch is the same thing or not but I'm just going on the exact same issue i had in my Jeep. Expensive part so i said f it and just used the headlight switch to turn the lights on, old school like. Hahah
