The tube on this vehicle is in the small pipe up front behind the right
headlight. Easy to get to.

The orifice tube is in the inlet of the evaporator. The accumulator, which
catches the excess liquid freon, is probably up front. Orifice tube systems
flood the evaporator under some conditions, so there must be a tank to catch
the liquid rather than slug it into the compressor. Freeze protection is
provided by a pressure switch on the accumulator, which also acts as a low
pressure safety switch.
To change the orifice tube, you must remove the inlet line at the evaporator,
the tube will be an insert. A real PITA to remove, too.
I agree, you should check the oil in the system. Usually the best way is to
remove and empty the compressor, then refill with the correct amount.
