Question Climate control

Pulling my hair out.
W 163 . AC only blowing outside air (no cooling). Freon is good but not circulating. Compressor seems to be fine. Tried resetting control panel, it flashes but never stops flashing. Have noticed that aux fans don't come on when ac is on.

You need to update your user info using Control Panel. Model year and your location.

If you are using mobile device look here. https://www.benzworld.org/forums/w16...l#post17015001

That would be the one ! All functions work, meaning fan , airflow , temp but no cold air. Pressing "REST" and "REDEFROST" gets the lights flashing but they do not stop flashing.

I think you meant Defrost. What that suppose to accomplish?

This is digital controller with tons of diagnostics but you will need capable scanner to access them.
