Hello I have a 03 G35 coupe ,problem is when it starts up sometimes the instrument cluster does not light up, the heat/ac and radio don't work, everything else is fine. I fix this by tilting the steering wheel up or down until there is a good connection I hear a relay click and everything comes back on and it works until I turn off the car. It looks like theres a bad connection somewhere, I cant find what it is I tried disconnecting the different connectors to the steering wheel didn't work.. I saw on Edmunds forum many people had similar problem where ac, radio and dash either don't work or ac is always on and you cant control the radio.. some people had success by having the radio repaired by a shop or getting a new aftermarket radio.. in my case im not sure its the radio if it is fixed by tilting the steering wheel.. has anyone solved this problem?
thanks

sorry for the troubles...have you tried the FSM to help locate the wires?

I'd start by taking the lower portion of the dash apart to find the bad connection. Can't be too many connections being moved around by the tilt wheel.

I found the problem its either the ignition switch or the connector on the ignition, the connector looks good though it makes good contact so it must be the ignition, another problem I have now is the vcd slip and brake lights are on and the OBD connector gives a "link error" when I connect the code reader, I wonder if the ignition could be causing this problem also

Maybe. I'd go ahead and replace the ignition as you already know it seems to have a problem
