I have an 02 wrx and when just have my day time running lights on only the left head light works. and same goes for when I turn on my normal lights. However when I turn on my highbeams only the right headlight works and the left light is completely out. any help is greatly appreciated. thanks

have you checked your bulbs??

that's usually an indication that one of the bulbs have gone out. you might as well replace both though since they tend to go out around the same time.
