I have 1998 Ford F150 3dr Base V8, 5.4L, Vin-L..
Back in December my Instrument cluster stop working, it was very humid at night. I found that Mini Fuse #29, 5 amp had blown, the one that powers the Instrument Cluster. I replaced the fuse, a week or so later the fuse blew again. I replaced the fuse, it blew again, only this time sooner. I replaced it again, it blew again, even quicker. So now it blows the moment I turn on the Ignition key to start the vehicle instantaneously...
I tried using a power probe to check problem. If I apply power to the Fuse Circuit using the Power Probe the Instrument Cluster and all the gauges work on, but it'll still blow fuses. I don't have a circuit diagram to diagnose this problem.
Thank you
