Hi All, New to the group and looking forward to all the knowledge.

I have a 2010 gl350 and have had issue with the 3rd row seat aircon. "Never worked since purchased used car."
It just won’t work.


Just wondering if anyone has had this issue or experience with it.

What’s been tested and done to date.

External temp sensor tested - all good
Internal dash sun sensor tested - all good

AC has been tested and gas is at the correct levels with no leaks.
Rear ac unit left side boot.
Electronic TX vale tested - ok
Blower tested - ok

System tested by power bypass tested and pipes go cold and air is delivered to ceiling vents.

3-zone automatic climate control

unit in dash has the infrared spot - I’ve heard that this could be the issue but not sure how to test it at present.
Computer have been run and no errors.

Any help would be greatly appreciated.

This is my unit in the car
19 Interior temperature sensor
