mercedes CLK 320
Unhappy EC light on and AC not working and emergency electroventilators on.

I have a CLK 320 cabrio, 10 days ago sometimes the EC light on and AC not working, but sometimes working right. When AC not working radiators fun working very quickly. I change sendor pressure of AC and I think the problem solver but today the car is the same failure.
I dont understand nothing.

Sounds like an intermittent electrical problem. Broken wire or bad connection. Beyond saying that I can't help you much, sorry.

Dump the AC codes with the REST button and post #7. Also post #3, 4, and 5. If you don't know how to dump the AC codes, look here.
