REMOVAL
(1) Open hood and disconnect the negative battery
cable remote terminal from the remote battery post
(Fig. 13).
(2) Remove right under panel silencer.
(3) Disconnect wiring connector for evaporator

(4) At center of heater housing, locate evaporator
probe access plate. Using a flat blade pry tool, pull
back on the locking tab. Twist the access plate
counter clockwise one-quarter turn and remove plate.
(5) Pull probe out of evaporator core. This plate
must be pushed inside the A/C unit and orientated in
such a way that the plate can be removed.
INSTALLATION
For installation, reverse the above procedures. The
new probe must not go into the same hole (in
the evaporator coil) that the old probe was
