The rear AC button on the dashboard is not illuminated, nor is the switch for the third row.

[slingshotvictim]

On my 2016 SXL, I have inspected the fuses located on the lower driver's side of the dashboard and in the engine compartment, changing them individually without success in illuminating the rear AC button on the dashboard or the third-row switch; thus, there is no air conditioning accessible for third-row passengers. Are there any further accessible fuses to inspect, or might it be a relay, or another component that I can easily examine?

I would appreciate assistance.

A potentially forgotten fuse is designated as "MODULE 6," which is a 7.5A fuse. The description is so ambiguous that it may have escaped your notice. This is located over your left knee.

Nonetheless, this fuse is not exclusive to the rear air system; so, if it were malfunctioning, you may encounter many other concerns, including one that is certain to be present in your trim level, the "Front Seat Warmer Control Module." It may be an inappropriate time of year; nonetheless, are there any concerns about that?

Additionally, I am inquiring if the knob illuminates appropriately at night on the back control. It operates on a distinct circuit from the module power, however shares the same harness to the back. Attempting to eradicate one possible issue.

Thank you for your suggestion. For the sake of thoroughness, I will attempt to replace the small module 6 fuse; however, I am skeptical that it is the source of the issue, as we utilized the heated seats without incident last winter. I first identified this problem last summer while the third row was occupied during a trip with my grandchildren. I am uncertain about the duration of this malfunction, since I have hardly used the third-row air conditioning since purchasing the vehicle new. I am uncertain if the back control knob illuminates at night when the headlights are on, or if it ever did so. Uncertain about what the illumination from the headlights will indicate, assuming it provides any information at all. I now believe I need to inspect the wiring connections for the dashboard rear AC button and the third-row control/switch to confirm their security; however, I imagine they are snap-together plugs that are typically rather secure. Inspecting the connections visually is likely to be a cumbersome task, particularly for me to reach the connection at the rear control, since the only access panel nearby does not expose the wiring for it.

Should I be in your position, I would endeavor to examine other available fuses, relays, or components to diagnose the malfunction of the rear AC button and third-row switch.

[slingshotvictim]

Thank you for the recommendation. I have checked many relays with a meter, confirming their functionality, and I have used spare fuses to temporarily replace the pertinent fuses, as specified in the owner's handbook, but to no avail. I will test additional fuses with temporary replacements when time allows.

Update: Following an examination of the fuse lists in the owner's handbook, I have broadened the testing to include any fuses that are or may be linked to the air conditioning, blowers, and related components. I further conducted retests on relays. Failure to achieve achievement. In the future, I would consider having a dealer inspect it; but, due to the seldom use of the third row for passengers, the cost-benefit analysis does not make this an immediate priority.

Disappointing!

Perhaps ecanderson can consider an other focus. I trust you will ultimately identify the cause of the issue.

It would be beneficial to ascertain if the back controls are illuminated. Otherwise, there is a total disruption in the harness connection between the front and rear, maybe at the module itself. The lights should illuminate irrespective of their functioning condition, since they are powered by the cabin lighting circuit rather than the AC circuits. I was rather disregarded in post #3.
