Instrument Cluster
My 2001 330i displayed the battery light and my car would not start. I also noticed that the B+ jumper connection was getting very hot as evidenced by the melted cover and pieces of metal weld at the connection point. I replaced the B+ jumper connector and changed the battery but the instrument cluster does not work --> only the the check lights for airbag and ABS light up when I turn the ignition switch to ON or Ignition position. I checked the fuses (F10, F34, and F43) and has power passing through them. I also checked the Alternator output with load (headlights and AC) and it was 14.01 volts. Where could the problem be? I don't know how to proceed. Please advice, anyone?

I checked fault codes and it read Fc 19 83 84 which was Table 19 of the codes: 83-Timeout, CAN-INSTR 2 and 84-Timeout, CAN-INSTR 3. I found that CAN stands for Controlled Area Network but cannot find anymore information beyond that.
I went further to remove the ignition switch and checked for any obvious damage and checked for continuity. This was what I found: Pin OFF ON IGN Pin OFF ON IGN Pin 1 X 5 8 2 X X 6 X 9 3 X 7 X 10 @ "ON" position contacts 2-6 are connected; @ "IGN" position contacts 2-6-9 are connected, 3-7-10 are connected, and 1-5 are connected. After reassembly of ignition switch, I started car again but instrument cluster was still dead and I noticed that the radio did not power up anymore. Everything else works including the light that illuminates the instrument panel. I re-checked the alternator output voltage with load and all fuses inside the globe box including the hidden high-amp fuses plus the fuses inside the eBox; all were passing voltages through them. I ordered a new ignition switch (just in case); will install when received.

Installed new ignition switch. Checked main fuse inside the trunk and rechecked all fuses --> no progress made. The radio powered back up as I tested my sunroof. I forgot to mention that the backup lights for the instrument cluster works --> to me it means power is going into the instrument cluster.
My A.C. is not working anymore; it just blows warm air. Last edited by bimmer330i; 01-05-2015 at 11:16 PM.. Reason: additional info added |

I replaced the instrument cluster with a used unit. All problems went away including my A.C. problem.
