Question about 2003 Nissan Altima
Fuses are checked by removing them(one at a time) and holding them to the light to see if the link inside the fuse has separated.What I use because my eyes aren't what they once were is a electrical tester( available at any parts store) set on the continuity setting.Apply the probes to each side of the fuse and you should hear a loud peep indicating the fuse is good. no peep you have a bad fuse.As far as relays are concerned this is a bit different. A relay uses a small electrical current to engage a larger current. They are an electro-magnetic device.If you can hear them click that means they are working.On any relay there will be two smaller wires and two heavy ones.The lighter wires will engage the relay the larger wires carry the load.The meter will tell you if there is current going to the relay to activate it and also if there is current coming out the other side .For this you want a voltage setting on the meter of at least 12 volts.This may be a two person job,one at the meter and one at the key. good luck
