section of this group. If not OK, replace the faulty
ambient temperature sensor.
SENSOR CIRCUIT TEST
(1) Turn the ignition switch to the Off position.
Disconnect and isolate the battery negative cable.
Disconnect the ambient temperature sensor wire har-
ness connector and the HVAC control head unit con-
nector.
(2) Connect a jumper wire between the two termi-
nals in the body half of the ambient temperature sen-
sor wire harness connector.
(3) Check for continuity between the sensor return
circuit and the ambient temperature sensor signal
circuit cavities of the HVAC control head unit connec-
tor. There should be continuity. If OK, go to Step 4. If
not OK, repair the open sensor return circuit or
ambient temperature sensor signal circuit to the
ambient temperature sensor as required.
(4) Check for continuity between the ambient tem-
perature sensor signal circuit cavity of the HVAC
control head unit connector and a good ground. There
should be no continuity. If OK, refer to Compass
Mini-Trip Computer in the Diagnosis and Testing
section of this group. If not OK, repair the shorted
ambient temperature
required.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Locate the ambient temperature sensor, on the
right side of the radiator yoke behind the grille (Fig.
6).
(3) Disconnect the wire harness connector from the
ambient temperature sensor connector receptacle.
(4) Remove the one screw that secures the ambient
temperature sensor bracket to the radiator yoke.
(5) Remove the ambient temperature sensor from
the radiator yoke.
INSTALLATION
(1) Position the ambient temperature sensor onto
the radiator yoke.
(2) Install and tighten the one screw that secures
the ambient temperature sensor bracket to the radi-
ator yoke. Tighten the screw to 5.6 N·m (50 in. lbs.).
(3) Reconnect the wire harness connector to the
ambient temperature sensor connector receptacle.
(4) Reconnect the battery negative cable.

UNIVERSAL TRANSMITTER

DESCRIPTION
On some models a Universal Garage Door Opener
(UGDO) transceiver is standard factory-installed
equipment. The UGDO transceiver is integral to the
overhead console. The only visible component of the
UGDO are the three transmitter push buttons at the
rear of the overhead console. The three UGDO trans-
mitter push buttons are identified with one, two or
three raised tactile bumps so that they be easily
identified by sight or by feel.
Each of the three UGDO transmitter push buttons
controls an independent radio transmitter channel.
Each of these three channels can be trained to trans-
mit a different radio frequency signal for the remote
operation of garage door openers, motorized gate
openers, home or office lighting, security systems or
just about any other device that can be equipped
with a radio receiver in the 286 to 399 MegaHertz
(MHz) frequency range for remote operation. The
UGDO is capable of operating systems using either
rolling code or non-rolling code technology.
The UGDO cannot be repaired, and is available for
service only as a unit. This unit includes the push
button switches and the plastic module.
