It's really an ECM relay, not an IPDM relay. The IPDM is the fuse and relay box located in the engine compartment and it has its own CPU. The bad ECM relays would cause dash lights to flash, engine to surge and stall, etc., almost like the vehicle was possessed. At first, Nissan said the relay was not serviceable separate from the IPDM, so they were replacing the whole IPDM. Then people were finding relays available on the aftermarket for around $12 and replacing the bad ECM relays and Nissan decided that it actually was serviceable, and much cheaper, to replace just the ECM relay. I believe they know sell the relay for just a few dollars, which, for some, makes it cheaper and more practical to just replace the recall then spend the time and gas to have the dealer replace it under the recall.
As far as the clicking noise you are hearing, I can't tell you without hearing it for myself. Perhaps you have a bad starter motor? Might be worth seeing if power is getting to the starter solenoid when the key is turned to "start."
