Front Sam or faulty suction fan
Hello all. New member here. My name is Todd and I live in Florida. I have a problem with my dash or front Sam. Every few days, my 2007 E320 bluetec will stop showing the directionals in the dash along with the high beam indicator. All the lights work correctly outside but not on the dash. I can disconnect the battery and the problem goes away for about 4 days. I noticed a code for engine fan fault. I cleared the codes and disconnected the fan module under the hood. Fault code didn’t come back. So I reconnected the fan and it was fine for about a week. Now it started again. Any ideas?

The dashboard is not involved with controlling suction fan - These two issues are not directly related unless gateway is faulty ("battery" reboot
).> Faulty CAN networking....
Post WHOLE chassis scan to see what other modules are hosting fault codes.
You need to find out all the participants in this chaos... it may be bad GND connections, low voltage drain, rain leak soaking.
