Hi, new to site, bought a 2002 f150 last week, seems to have the heater/air blender door going on, checked at door and switch, no power. thought fuse 5 was for that, but my plain jane truck doesn't seem to have a fuse in that position, or prongs to put one in. Supposed light blue wire with pink stripe from **** was to be hot when key on. Thinking of running wire from another source if this is true.

 

Former owner had pushed connectors for fuse out the back of the fuse box, ( I suppose he had wired his work radio there) fixed that installed fuse, blender door works and a/c works
