I have a short somewhere in my F150. It keeps popping the fuse that works my lights, electronic shift, radio & also my a/c kicks on when I turn on my heat. I need to figure out the problem so that I can fix it myself. Any ideas??

What are you doing that triggers the fuses to blow or does it occure randomly? Day &/or niight? Last repairs preformed? Radio factory or aftermarket? Yr/mdl.

Take the cables off the battery and put a multimeter between them. You should be reading a short. Pull fuses till you find the circuit in question.

Did all this happen after a rain? If so, the leak is either the firewall, driver's side front windshield halfway up or sun roof. I had a leak at the windshiled that was dripping down the A pillar and the way the wire was taped up, it acted like a funnel and sent the water down to the fuse block. My truck did all kinds of electrical things with the key on and off. Not sure if you have the same problem. If you look under the drivers side dash, or ever had a small puddle or water on your mat, it may be your problem. You can look up underneath where the main wiring comes in by the A pillar and look for drip marks on the metal at the area where the electrical tap meets the metal at the top. Hope this helps.
