Use an adjustable vacuum test set (Special Tool
C-3707-B) and a suitable vacuum pump to test the
HVAC vacuum control system. With a finger placed
over the end of the vacuum test hose probe (Fig. 3),
adjust the bleed valve on the test set gauge to obtain
a vacuum of exactly 27 kPa (8 in. Hg.). Release and
block the end of the probe several times to verify that
the vacuum reading returns to the exact 27 kPa (8
in. Hg.) setting. Otherwise, a false reading will be
obtained during testing.
VACUUM CHECK VALVE
(1) Remove the vacuum check valve. The valve is
located in the vacuum supply tube (black) at the
HVAC system vacuum tee.
(2) Connect the test set vacuum supply hose to the
A/C Heater Control side of the valve. When con-
nected to this side of the check valve, no vacuum
should pass and the test set gauge should return to
the 27 kPa (8 in. Hg.) setting. If OK, go to Step 3. If
not OK, replace the faulty valve.
(3) Connect the test set vacuum supply hose to the
engine vacuum side of the valve. When connected to
this side of the check valve, vacuum should flow
through the valve without restriction. If not OK,
replace the faulty valve.
A/C HEATER CONTROLS
(1) Connect the test set vacuum probe to the
HVAC vacuum supply (black) tube at the tee in the
engine compartment. Position the test set gauge so
that it can be viewed from the passenger compart-
ment.(2) Place the A/C Heater Mode Control switch
knob in each mode position, one position at a time,
and pause after each selection. The test set gauge
should return to the 27 kPa (8 in. Hg.) setting
shortly after each selection is made. If not OK, a
component or vacuum line in the vacuum circuit of
the selected mode has a leak. See the procedure in
Locating Vacuum Leaks.
CAUTION: Do not use lubricant on the switch ports
or in the holes in the plug, as lubricant will ruin the
vacuum valve in the switch. A drop of clean water
in the connector plug holes will help the connector
slide onto the switch ports.

(1) Disconnect the vacuum harness connector from
the back of the HVAC control head(Refer to 24 -
HEATING & AIR CONDITIONING/CONTROLS/A/C
HEATER CONTROL - REMOVAL).
(2) Connect the test set vacuum hose probe to each
port in the HVAC housing half of the vacuum har-
ness connector, one port at a time, and pause after
each connection. The test set gauge should return to
the 27 kPa (8 in. Hg.) setting shortly after each con-
nection is made. If OK, replace the faulty A/C Heater
Control. If not OK, go to Step 3.
(3) Determine the vacuum line color of the vacuum
circuit that is leaking. To determine the vacuum line
colors, refer to the Vacuum Circuits chart (Fig. 4).
(4) Disconnect and plug the vacuum line from the
component (fitting, actuator, valve, switch, or reser-
voir) on the other end of the leaking circuit. Instru-
ment panel disassembly or removal may be necessary
to gain access to some components. See the appropri-
ate service procedures.
