Supplement to this post. I found the relay on the IPDM tucked away against the firewall passenger side. Went to two local Nissan dealers in my area and they couldnt even find the relay on their spare parts computer. I've ordered a couple on-line but the problem now is I am getting "ERROR" displayed on the dash when I try to start the car. Battery is charged..all functions still work..but car wont start ?? Any clues here?? thanksI have a 2013 STX550. The AC stopped working literally overnight. I cant hear the compressor relay activating. Anyone know where the AC relay and fuses are located. Thanks
