5. LEAK TEST—LOW-PRESSURE SIDE
1) Begin at the connection of the low-pressure tube to the
evaporator, and work your way along the low-pressure of
the system to the compressor. There are three places to
check on each tube connection.
2) Check the area.
(1) Check the area where the fitting joins the tube.
(2) Check the area where the two parts of the fitting
join each other.

6. CHECK THE FLEXIBLE HOSES
Visually inspect the rubber portions of the flexible hoses for
cracking. Probe the rubber section, including the ends of
any insulators or protectors which may cover sections of
the rubber hose, and near the ends where the rubber
meets the metal collar.
NOTE:
Be certain to move the probe slowly [approximately 25 mm
(1 in) per second] when probing along any length of hose
or tube.

7. CHECK THE EVAPORATOR ASSEMBLY
1) Use one or both of the following methods to check the
evaporator assembly.
2) Remove the drain hose from the case drain nipple. Hold
the probe at the end of the case drain nipple for at least 10
seconds. Be certain to reconnect the drain hose when fin-
ished.
3) With the ignition key in the“ACC”position, run the
blower on high speed for 1 minute, then turn the blower off.
Place the probe in the center instrument panel vent, an turn
the blower on low speed for 1 to 2 seconds, then turn the
blower off. Leave the probe in the vent for at least 10 sec-
onds.
