E320 2001 stuck in EC mode + EB1419 faulty code
My E320 was stuck in EC mode (light on) and thus could not get AC to work.
I found several related topics explaining how to obtain the on-board diagnosis codes via N22 control module on benzworld.com and mercedesshop.com forums as well as http://www.continentalimports.com/ser_ic40142.html and http://www.eclassbenz.com/acdiag 01: 98 in-car temp 02: 76 outside temp 03: 69 heater-core temp left 04: 69 heater-core temp right 05: 73 evaporator temp sensor 06: 66 ECT sensor 07: 04 refrigerant pressure 08: 67 refrigerant temp sensor I also got the following Faulty codes: EB1419 electromagnetic clutch EB1234 sun sensor (safe to ignore based on read articles) I then followed the instructions posted by Sokoloff (MB bulletin 37/99-2) and could turn off the EC mode: http://www.peachparts.com/shopforum/tech-help/86110-210-chassis-climate-control-problem.html I have not yet replaced the evaporator nor the refrigerant temperature sensor at this point. My AC is still not blowing cold air though. The faulty electromagnetic clutch code EB1419 does not sound like a simple problem to me. So, before replacing any unnecessary parts, just wonder if any MB tech gurus here can point me to the right direction? Appreciate much your inputs... John |

Read stevebfl's article again. You can clear codes from the display.

Terry,
Would you mind provide a link or thread ID? I searched and Stevebfl has posted like 500 threads total! |
You need to check the clutch. Ensure that it has continuity by disconnecting the lead and checking the resistance to ground. Also ensure that you can turn the compressor input shaft by hand.
