CLS interior temp sensor?

[JeffT]

Had a few gremlins with 4-zone auto climate control so thought maybe the temp sensor needs a clean/dust. Assumed it would be behind the little black plastic mesh fitting in the dash to left of steering wheel. When I removed this there was nothing there. I was expecting to see some sensor and wiring. Could it have fallen behind the dash or is this just a redundant fitting and system picks up temp elsewhere? Maybe as its 4 zone there are 4 sensors elsewhere for each zone.

Defo should have a small aspirator fan and sensor there to monitor the temperature in the lower area in the vehicle interior.

There is a second sensor in the OCP to monitor the temp in the upper cabin area

Thanks - time to go fishing then. Could explain a few things as well
