A/C problems
kjhansen:
Where is the POA valve located in the 87 TR? I think mine is malfunctioning or clogged.
ULYCYC:
They stopped using POA valves in the mid 70's. Do you mean expansion valve/orifice tube?
Steve Wood:
that's right. Orifice tube is it
ULYCYC:
Good video to explain removal..

Steve Wood:
I have been fortunate with mine but both have been sitting for a long time without using the AC. I bet I need one of those tools! that's neat!
Also, I suspect any of our cars would benefit from a new condenser. If the condenser does not pull the heat out of the freon, it ain't gonna cool very well
