98 S10--Is there a relay box to the headlights

After hitting a deer with my S10, I have fixed it back up, but when I turn my headlights on-- the left side(where the deer hit) headlight is very dim. When just the running lights are on it seem to be normal light. Its only once I turn on the head lights it goes dim. Is there a relay box or something that I should replace also. If so where is it?

At the headlight connector, follow the ground wire to where it connects to the body, you'll probably find it loose or not connected.

after replacing a fuse now the lights are back to normal. Guess I figured if the fuse would have been blown I wouldn't of had any headlight. Anyway thanks for the help.
