=== Output System ===

This is a bit more involved. Short all three prongs together. The climate control system will now cycle through all of its modes over and over again.
'''1) Air Mix Doors:'''

Set the Temperature Set number to 8 and then 9. For each setting look at the numbers appearing in the Ambient Temperature window and feel the air coming out of the vents.
Here is what you should see and feel:

104 and fully hot air for 8 sec

86 and lukewarm air for 4 sec

68 and fully cold for 4 sec

Most likely you will not see the exact numbers above. I believe, it is ok as long as the numbers are fairly close AND the difference between fully hot and fully cold numbers is no larger then 54 and no smaller than 18
From this point on, you no longer need to play with the set temperature buttons. You merely watch the system while it cycles through all its modes and check on things. Unfortunately, the best way to describe this part is through pictures and ASCII will not even come close. On the bright side, the rest of the tests mostly check the components that you can check by cycling your system through normal modes of operation manually. I will give a brief description. The systems are presented in the order that they are cycled through.
'''2) Outlets'''

Watch the system cycle through the different outlets and their combinations and check that the air is coming out of the same vent as is shown on the display. Also, make sure the air temperature is right (cold or hot when ac is on or off). The system should spend 4 seconds in each of the following: defrost, demist, bi-level, vent.
'''3) Intake door'''

Watch the intake door spring (I have not done this and don't yet know how) as the system spends 8 seconds in full recirculation, 4 seconds in partial recirculation, and 4 seconds with only outside air coming in.
'''4) Water cock'''

Watch the [https://dev.z31library.com/xenonzcar_archive/z31/images/Digital%20Climate%20control/watercock1.jpg water cock] (near the battery) and/or display, The water cock should be on for 8 seconds and off for 8 seconds
'''5) Compressor Clutch'''

Should be off for 8 seconds and on for 8 seconds. Can watch the A/C compressor clutch and/or the display.
'''6) Blower motor'''

Watch it increase in 3 steps from off to full blast. Feel the vents and watch the display.

Hope this helps with troubleshooting the Factory Automatic Climate Controls in your Z.
