I have a 2001 Mercedes E320. It's hot summer now, but I can't turn AC on. I'm stuck in the EC (economic) mode. No matter how many times I push the EC button, it doesn't turn off. I checked fuses, recharged freon (actually R134a). None helped. I pulled the control console out last night, but could not see a way to fix the problem. All the wires are bundled into two clusters and pluged into two sockets. Any idea what I should do? Thanks a lot.
