go to next step.
3. Turn ignition off. Disconnect right air temperature actuator. Turn ignition on. Observe RH
MIX MTR POSITION FEEDBACK parameter in HVAC data list. If scan tool indicates
RH MIX MTR POSITION FEEDBACK parameter is more than 250 counts, go to next
step. If scan tool indicates RH MIX MTR POSITION FEEDBACK parameter is 250 counts
or less, go to step 8 .
4. Turn ignition off. Connect a fused jumper wire between terminals No. 9 (Dark Blue wire)
and No. 7 (Gray/Black wire) of right air temperature actuator. Turn ignition on. Observe
RH MIX MTR POSITION FEEDBACK parameter in HVAC data list. If scan tool
indicates RH MIX MTR POSITION FEEDBACK parameter is less than 5 counts, go to
next step. If scan tool indicates RH MIX MTR POSITION FEEDBACK parameter is 5
counts or more, go to step 9 .
5. Turn ignition off. Connect a fused jumper wire between terminals No. 9 (Dark Blue wire)
and No. 10 (Yellow wire) of right air temperature actuator. Turn ignition on. Observe RH
MIX MTR POSITION FEEDBACK parameter in HVAC data list. If scan tool indicates
RH MIX MTR POSITION FEEDBACK parameter is more than 250 counts, go to step 7 .
If scan tool indicates RH MIX MTR POSITION FEEDBACK parameter is 250 counts or
less, go to next step.
6. Disconnect right air temperature harness connector. Check continuity between ground and
terminal No. 10 (Yellow wire) of right air temperature actuator. If continuity exists, repair
short to ground in Yellow wire between right air temperature actuator and terminal C10 of
HVAC control head. After repair, go to step 15 . If continuity does not exist, go to step 12 .
7. Measure voltage between ground and terminal No. 10 (Yellow wire) of right air
temperature actuator. If voltage exists, repair short to voltage in Yellow wire between right
air temperature actuator and terminal C10 of HVAC control head. If voltage does not exist,
check continuity in Yellow wire between terminal No. 10 of right air temperature actuator
and terminal C10 of HVAC control head. If continuity exists, go to step 11 . If continuity
does not exist, repair open in Yellow wire and go to step 15 .
8. Check continuity between ground and terminal No. 9 (Dark Blue wire) of right air
temperature actuator. If continuity exists, repair short to ground in Dark Blue wire between
right air temperature actuator and terminal C3 of HVAC control head and go to step 15 . If
continuity does not exist, go to step 12 .
9. Check voltage between ground and terminal No. 6 (Dark Blue wire) of right air temperature
actuator. If voltage exists, repair short to voltage in Dark Blue wire between terminal C3 of
HVAC control head and right air temperature actuator. After repair, go to step 15 . If
continuity does not exist, check continuity in Dark Blue wire between terminal No. 6 (Dark
Blue wire) and terminal C3 of HVAC control head. If continuity exists, go to next step. If
continuity does not exist, repair open in Dark Blue wire and go to step 15 .
