Look in the area behind the AC compressor where the hoses bolt on. This can be done by removing a splash shield in front of the left wheelwell.

Cannot locate valve to add 134a refrigerant in a 2000 lincoln navigator

What your looking for is called a service port. On a 134a system there are two of them, located in the refrigerant lines. One port will be larger diameter than the other. The large one is the "high" side and the small one is the "low" side. refrigerent is added to the low side with the system running. You really should use a manifold gauge set to see what the pressures are before adding any refrigerant. If the system has too much, it is as bad as not enough.

Dual heat one side cool other side hot

This may be a shortage of 134a refrigerant in the a/c system. this may also be a dual hot water control valve. either it is expensive to just put on parts, I'd suggest that you get the system checked out first.
