Well I checked today while my car was at the shop and fuse 5 (everything that doesn't work) is fine and has 12 volts on both sides with the key in, but nothing works that comes off of it, puzzles me alittle
a volt meter have almost no load so it might read 12V but he moment you put a load on it it might drop to 0 or close to it. Turn something on and check again. Other possible issues is the down stream connectors might be disconnected
