Aircon stopped working
 

I drive a 2000 C280, and did not use the aircon for about 3 months (operate fans on EC). The reason for this is because it was winter time and I though I would save the aircon instead of kicking in/out all the time.

Yesterday I switched on the aircon for the first time (disengage EC switch), and it did not make the air cold. I can hear the "sound" change when engaging/disengaging the EC switch, as normal when it works. The fan still blows, but no could air.

Any suggestions on how to troubleshoot this problem?

Start here. Pay special attention to the Chart 1 link in the "AC Diagnostics" section.

You don't have the left/right buttons but you get the idea.
Let us know what values you get from the display.

Hi forp,

Thanks for the suggestion, but my car does not have climate control. It's still manual.

Any other way to diagnose?

Had it checked out at the service. Low gass pressure. Apparently no noticeable leaks?? Anyway, regassed it and is working now.
