Re: [FWDLK] air conditioning

I am not sure about old MOPARS but it sounds similar to the "Expansion
Valve" setup that GM used in the early in the 70's (in the 80's they went to
an "orifice tube" valve that I believe is still used today).  If so the
capilary tube will attach to one of the tubes that go inside the car to the
Evapeator.  I am not sure which one but i believe that it is used to sense
the temperature of the lines and operates the valve.   Check an A/C manual
from any 60' or early 70's MOPAR and it should help you figure it out
