stock headlight q for a 94

I had some projector headlights (gay, i know) and I recently put the stock lights back on. However, the the left front light (if you were sitting in the car) has a problem. the low beam does not light at all, and the bright is very dim (like an amber yellow). Then when I turn the brights on the left light goes completely dead, but the right side works perfect (always). I checked the harness to the low beam and it is getting the same amount of power as the right light, so I know that is not thew problem. I think its a bad ground, but I'm not sure. Behind the lights, bolted to the frame by the fender (if you have a cai its really easty to see) there is a plastic white box w/ a bunch of black wires going into it. (I assume these are grounds for various electrical components) I switched the plastic pieces from each side to the other but it didn't fix the problem. Next I cut the ground wire coming out of the harness and ran it to a nut on the frame so I know it's grounded, and that didn't fix the problem either. Also I switched bulbs and that didn't work, so I know its not the bulb too. I'm pretty much put of ideas, (Maybe the harness is bad? or the light? :banghead: ) Sorry about the long post, but i've tried alot and am looking to see if anyone else has had this problem or has new ideas (also, the light worked before I took it off, and was less then a year old due to a minor accident)

perhaps the headlight relay. the lights do all kinds of goofy stuff when they are going. it's up in the top left of the engine compartment.

p.s. projector lights are cool
