i did some searching. cant find anything.

the problem is that the drivers side headlight is dim. not out just dim. the passengers is fine. if you turn on the brights the check engine light comes on and if you flip back to dim at this point the high beam indicator remains on.
i have busted out the multimeter and all the pins match up voltage wise from side to side (from what i seen) anyone know where to start or seen this problem before.

thanks for any help
