13. Check for continuity between the given terminals of rear heater-A/C control switch connector B (10P) and the rear mode control motor 7P
connector.
Is there continuity?
YES - Check for loose wires or poor connections at rear heater-A/C control switch connector B (10P) and at the rear mode control motor 7P
connector. If the connections are good, substitute a known-good rear heater-A/C control switch, and recheck. If the symptom/indication goes away,
replace the original rear heater-A/C control switch.
NO - Repair any open in the wire(s) between the rear heater-A/C control switch and rear mode control motor.
Air Mix Control Motor Test
Air Mix Control Motor Test
1. Disconnect the 7P connector from the air mix control motor.
NOTE: Incorrectly applying power and ground to the air mix control motor will damage it. Follow the instructions carefully.
2. Connect battery power to the No. 1 terminal of the air mix control motor, and ground the No. 2 terminal; the air mix control motor should run, and
stop at Max Cool. If it doesn't, reverse the connections; the air mix control motor should run, and stop at Max Hot.
3. If the air mix control motor does not run in step 2, remove it, then check the air mix control linkage and door for smooth movement.
-
If the linkage and door move smoothly, replace the air mix control motor.
-
If the linkage or door sticks or binds, repair them as needed.
-
If the air mix control motor runs smoothly, go to step 4.
4. Measure the resistance between the No. 5 and No. 7 terminals. It should be between 4.2 to 7.8 kOhms.
5. Reconnect the air mix control motor 7P connector, then turn the ignition switch ON (II).
6. Using the backprobe set, measure the voltage between the No. 3 and No. 5 terminals.
Max Cool-about 0.7 V
