Also which relay, the HVAC blower motor or the AC compressor clutch relay?
The blower motor relay is in the fuse panel/junction block and should just pull out.
The AC clutch relay however is built into the IPDM (intelligent power distribution module) and is not a serviceable part, you replace the entire module to replace the relay and it has to be programmed with the VIN number to match your car.
That is the same for Infinity 2008 G35 & M35 And 2009 G37 & M35 models.
