I plan to replace the AC Aux Fan wiring harness on my ML 430. My first step will be disconnecting the battery. What, if any, reprogamming will I need to go through after I reconnect the battery?

Thank you,

Jim Herold

You will need your radio code # to get it up and running and you will also need to turn the steering wheel lock to lock a couple times to resynchronize the steering wheel angle sensor for the ESP. Also don't forget to reset your clock etc. in the trip computer. My 2 cents.
