for the past 2 weeks my headlight has been acting up, 1 day it will work just fine, then i go to turn them on that night and only 1 works, but the next time i turn them on its working fine... now its got to the point that it hasnt came on for the past 2 days... i have already replaced the bubls so i know its not that... what can i do to diognose this problem myself?

 

got the same problem...

 

check the fuses man... i just had a headache of a problem for the last 2 weeks with both my headlights AND my taillights, and also my dash interior....
took it in, a blown fuse... yours sounds like it's probably loose... unpin all your fuses check if any are blown, and then put them back in...

 

ive been told its the ballast... but they said its weird how it works one day and not the next...

 

ive checked every fuse i could find...

 

i have the same problem on my 05

the dealer said it was fine

yeah right...
