low beam/ daytime running light wont work


Recommended Posts

My friend has a 2001 legacy outback. The low beam on the drivers side is out along with the daytime running light. I replaced the bulb and it still wouldnt work. I put the bulb that came out in the passengers side and it was blown.

I put the known good one from the passengers side into the drivers side and it still didnt work. I checked all the headlight related fuses and they are all good.

If anyone has any ideas on what I should check next...........

What should the voltage be going to the small bulb?

Yes I have had issues on '00obw with the little tabs for the bulbs not mkaing good contact (making me think bulb was blown but it wasn't).

 

DRL on that era is high beam bulb run at reduced intensity (via PWM pulse width modulation at the DRL module. PWM is also the modulation method the TCU uses for the auto trans solenoids).
