98 S-10 Fluid leak

Strange leak under passenger side, between wheel well and firewall. Seems
to
be coming from lower side of the air conditioner condenser. The plastic
box
or cover where  the 2 AC lines go in. The fluid appears to be radiator
fluid, it has the greenish color and does not appear to be Refrigerant
from
the AC, and the AC works great but has a strange radiator smell to it.  My
original thinking was it was the heater box but the lines are to far away
from the leak, around the middle of firewall. 

Any Ideas?

Thanks
