5. Check for continuity between the No. 1 and No. 2
terminals of the A/C pressure switch.
Go to step 6.
Go to step 14.
6. Reconnect the A/C pressure switch 2P connector.
7. Disconnect the climate control unit 30P connector.
8. Turn the ignition switch ON (II).
9. Measure the voltage between the No. 24 terminal
of the climate control unit 30P connector and body
ground.
Go to step 10.
Repair open in the wire between the climate
control unit and the A/C pressure switch.
10. Turn the ignition switch OFF.

11. Measure the resistance between the No. 2 and
No. 5 terminals of the climate control unit 30P
connector.
Check for loose wires or poor connections at
the climate control unit 30P connector and at the
A/C pressure switch 2P connector. If the
connections are good, substitute a known-good
climate control unit, and recheck. If the symptom/
indication goes away, replace the original climate
control unit.
Repair cause of high resistance in the
evaporator temperature circuit.
12. Make sure the A/C switch is OFF.
13. Measure the voltage between the No. 9 terminal of
under-dash fuse/relay box connector F (12P) and
body ground with the under-dash fuse/relay box
connectors connected.
Repair open in the wire between the
under-dash fuse/relay box and the A/C pressure
switch.
Refer to the multiplex control system
troubleshooting (see page 22-189).
14. Check for proper A/C system pressure (see page
21-66).
Replace the A/C pressure switch.
Repair the A/C pressure problem.

Check for a change in resistance by heating or cooling
the sensor with a hair dryer.
Compare the resistance reading between the No. 1 and
No. 2 terminals of the in-car temperature sensor with
the specifications shown in the graph; the resistance
should be within the specifications.
1. Remove the in-car temperature sensor (A) from the
dashboard, then disconnect the 2P connector (B)
and the air hose (C). Be careful not to damage the
sensor or the dashboard.
2. Install the sensor in the reverse order of removal.
Be sure to connect the air hose securely.

Dip the sensor in ice water, and measure the resistance.
Then pour warm water on the sensor, and check for a
change in resistance.
Compare the resistance reading between the No. 1 and
No. 2 terminals of the outside air temperature sensor
with the specifications shown in the graph; the
resistance should be within the specifications.
1. Lift the tab (A) to release the lock, and remove the
outside air temperature sensor (B), then disconnect
the 2P connector (C).
2. Install the sensor in the reverse order of removal.
