Try peeking behind the bumper and see if the left side frame rail has an alimunum box anchored to it. If so that could be the culprit, if not than it may be attached to the fan assembly with the fan.

Would you happen to have accesory number (A/C 580 or 581a) to identify the system fitted to your car? Is your fan mounted in the front of the condensor or is it mounted on the engine side of radiator?

My information shows a couple of different systems can be fitted to that production range of vehicles. Production date and A/C code number easily identify the system on your car.
