Outer Limits 4x4 Board

2006 R51 pathfinder aircon blower fuses constantly blows works for few minutes then blows any ideas why??

mate you could have a short in your fan speed switch or your fan speed resistors or your blower motor could have a short. you could check for a short or you could just bypass one thing at a time and see if the fuse blows. or you could get a 12v head light globe run 2 wires from that. remove the blown fuse while fault is still there ie leave car ignition on and the 2 wires from the globe put into where you removed the fuse. your globe will be bright and when you disconnect the item with the short your globe will go dull or out.
