I need some assistance. I am trying to replace the original Hella drivers side head lamps, and do not know how to proceed. I have removed the side light and grill, unbolted the support frame, and can not remove it from the car. It looks like the headlight wiper motor is hitting the inner frame. Can I replace the lights without removing the whole unit? I have never had to replace the whole unit and could use some advice. Thank you.
