W210 Climate Control Stuck in EC Mode
 

My wife and I bought a 99 E320 yesterday and the climate control worked great...until last night. Since then, the climate control has been stuck in EC mode, which locks out the a/c compressor.

Does anyone have any hints or tips for clearing this? The obvious step of pushing the button again doesn't work.

It's going to be 105+ again tomorrow, and we'd really like the a/c again!

Thanks for your time,

Charlie

It does that as a self-protection feature, you can't just clear it out. Usually it means you're low on freon, so there may be a freon leak that needs to be repaired.
On a 99, there is also the possiblity that there is a problem with the freon (refrigerant) level monitoring system, the dealer should be aware of this potential and know how to fix it.

Thank you for the info. I'll get it checked out right away.
