A few (hopefully small) electrical issues, need help
Hi guys I知 relatively new to this forum so I値l keep it short and simple, I drive a 2009 g37s coupe 6MT 190k KMS on it, I ran into and issue with my blower motor, the blower motor will not turn on, I fully replaced the fuse box and blower motor brand new and still nothing, I also have an issue where my reverse lights won稚 turn on, I replaced the fuse for the reverse lights and the reverse light switch in the engine which still did nothing for it, not too sure as to what the issues could be? Tested all fuses and the work.

Please elaborate when you say "fully replaced the fuse box."
Keep in mind there is a relay for the blower which is located (idiotically) behind the driver side fuse box. When the car is turned ON, the relay energizes and send 12V+ to the blower motor via 2 separate fuses:
Do you have a multimeter? If so, at the blower there should be a connector with three (3) wires. Unplug the connector first and then, with the ignition key ON, FAN ON:
1) check for 12V+ at the LARGE BLUE wire;
2) check for any voltage at the PINK wire; and
3) check for CONTINUITY at the LARGE BLACK wire (in other words, verify good ground).
Turn everything off before plugging the connector back in.
If you are not receiving 12V then you will have to check the relay.

As for the BACKUP LAMPS: what switch did you exactly replace and where on the gearbox was it located?
