The housing was
restored to it's original finish after a few
minor fiberglass repairs.
It was built
with a new evaporator,
resistor, blower
motor, new
Billet style POA Eliminator Upgrade valve that
closely resembles the original Frigidaire POA
valve.
The original Frididaire expansion valve was
restored.
The ambient sensor switch was
cleaned &
tested to function correctly.
For the
most part, this unit fits 1967-69 Firebird &
1967-68 Camaro with Big-Block engine with only a handful of
difference.

This unit was originally a 70 Camaro unit,
but was built for a customer who needed one
for a Firebird.
The housing was
restored to it's original finish after a few
minor fiberglass repairs.
It was built
with a new evaporator, 134a POA eliminator
valve, expansion valve, resistor and blower
motor.
The ambient sensor switch was
cleaned &
tested to function correctly.
For the
most part, these units are the same from
1970, 1971, 1972 and 1973 Chevy Camaro &
Pontiac Firebird, with only a handful of
difference.

Rebuild for one of
our customers that wasn't extremely particular,
like most C2 Corvette owners.
This unit was built using a new evaporator,
blower motor, resistor, high-fan relay and
replacement expansion valve.
The housing was restored, with a few minor
repairs.
The support clamp
between the two pieces was missing, so we
fabricated one for function purposes.
The STV (Suction Throttling Valve) was not
provided for us to rebuild.
INTERCHANGE -
For the most
part, these units are the same for 1963, 1964 &
1965 Corvette with factory air-conditioning.

Heater Box

A
recent rebuild of Dylan T's 87 Chevy truck a/c
heater box.
As is often the case with the mide 1985 & newer
square body trucks, this unit was damaged when
someone tried to replace the heater core, (These
are VERY tricky to disassemble without
damaging!) and the inner housing was literally
broken in half. We fixed it, cleaned &
tested the actuators, restored the rest of the
housing, installed a new diverter door deal and
calibrated so doors function correctly.
For the
most part, this unit with the plastic vacuum
actuators is correct for 1986 & newer square
body trucks.

Also called a
suction valve, suction throttle valve, POA valve
and other names, this is the piece that mounts
beside the a/c compressor, in the engine
compartment.
Its function is
to regulate pressure to insure the evaporator
coil does not freeze.
The exterior
metal components were zinc-plated.
New O-rings and internal diaphragms have been
installed.
Built to be used
with the old R12 refrigerant, but can be
calibrated for the newer 134a refrigerant during
the charging process.
This is done by removing the lever and using a
specialized tool to adjust the nut inside the
shaft to get the low side reading to 20psi. |
