A/C stopped working
Haven't used A/C for a long while (winter), and it won't turn on today. Press the A/C off button, it flashed a few times then stayed on.
Did a quick search, and found a couple of similar cases, but there is no updates on the solutions.
Is there a way that one can force the A/C on ? or some other ways to tell whether it is sensor related or freon charge ?

I haven't experienced this problem on the E class, but have worked on the same issue in the 2000 C-class. When the freon is low, the A/C system won't turn on, but the fan and heat still work fine. You can buy a pressure gauge for $10 from any auto store and check the freon pressure by connecting the gauge to the charging valve (in the engine bay). If it's low, just charge the system w/ freon; that also means there's a leak in the system.

I won't take it to just any mechanic. You should take it to a well-known good MB mechanic in your area. Check online for mechanic reviews in your area. I used yelp.com for some of the reviews. You can charge the freon for temporary use (it's an easy job), but if there's a leak, which seems likely, you should get it fixed anyway.
