N OT E
A/C evaporator harness wire colors identified at AC. Wire color may be reversed at A/C blower
connector.
CONTINUITY TEST
(1) Remove A/C evaporator subsystem
from doghouse (WP 0036 00).
(2) Remove A/C blower from evaporator
assembly (WP 0022 00).
(3) Is continuity measured on orange wire
from A/C blower connector male
terminal to A/C evaporator switch
harness connector black wire?
(a) If there is no continuity, repair A/C
blower black wire (See WP 0057
00, Fig j) or replace A/C evaporator
harness (WP 0027 00). Verify
repair, go to Step 18 of this fault.
(b) If there is continuity, go to Step 17
of this fault.
CONTINUITY TEST
(1) Is continuity measured on orange wire
from A/C blower resistor to A/C blower
connector male terminal?
(a) If there is no continuity, repair A/C
blower female terminal wire (See
WP 0057 00, Fig j) or replace A/C
evaporator harness (WP 0027 00).
Verify repair, go to Step 18 of this
fault.
(b) If there is continuity, replace A/C
blower (WP 0022 00). Verify repair,
