1999 ML430 AC compressor won't engage and remote locking system doesn't work
Hello everybody.
I have a problem with my 99 ML430. AC compressor doesn't engage (no leaks, low side over 100 psi, high side about the same), remote locking system and anti theft system don't work. I can lock and unlock the doors using the switch on the center console. I checked the continuity of the connection between the AC compressor and pin 28 on the N10 module and is fine. I can activate the clutch by supplying 12 volts to that pin with N10 removed. Do you thing that the All-Activity module N10 could be the source of my problems with this car ?
