2010 LX No heat or cooling second and third row

[Everlong]

Hi, had this beast for a while. Recently noticed it just blows cold air in the rear regardless of the heat setting thats used. Any ideas? Filter is clean, front hvac works fine. Tried all settings etc, front and back.

I'd start with Techstream and see if there are any "hidden" DTCs tripped, or sensors in the HVAC that don't appear to be reading correctly. Also, you might try putting settings on Max Cold/Heat. The LX has temp sensors in the cabin to determine how hot/cold the truck is to auto adjust heat/cool. If a sensor gets off, it can cause issues. Setting to Max either direction overrides the temp sensor control.

Hi, i did try setting it to max/min in both cool and heat.

******I did forget to mention that the center console that has all the adjustments for the rear blows warm when in heat mode *******

Where to get Techstream and the cable? Is it easy to navigate? Thank You

I also use my hvac in manual mode. Never on auto
