REMOVAL

Some LH models have heating elements that can-
not be replaced without replacing the entire leather
seat trim cover. Consult the Mopar parts catalog for
specific part numbers.
Do not remove the original heating element from
the seat or seat back cushion/trim covers. The origi-
nal element is permanently attached and cannot be
removed without permanent damage. Models with
replaceable heating elements are designed to be
applied directly over the original heating elements.
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the appropriate seat cushion or seat
back trim cover. Refer to the Body section of the ser-
vice manual for the procedures.
(3) Disconnect the inoperative heated seat cushion
or seat back element electrical connectors.
(4) Locate the wires leading from the inoperative
heating element and cut them off flush with the edge
of the original heating element.

INSTALLATION

(1) Peel off the adhesive backing on the back of the
replacement heating element and stick directly on
the foam cushion or on top of original heating ele-
ment.
CAUTION: During the installation of the replace-
ment heating element, be careful not to fold or
crease the element assembly. Folds or creases will
cause premature failure.
(2) Connect the new heating element electrical
connectors (Fig. 8).
(3) Connect the negative battery cable.
(4) Verify heated seat system operation.
(5) Install the appropriate seat cushion or seat
back trim cover. Make certain the seat wire harness
is correctly routed through the seat and seat back.
The excess wire between the cushion and back ele-
ments should be securely tucked between the rear of
the cushion foam and the trim cover.
