Blown Fuse

[billman61]

Hey,

I recently picked up a 96 F-150. Has 113,000 miles and is in great shape. Only problem is fuse # 8 blows, and I haven't been able to determine with complete accuracy which systems or components are powered from that fuse. If anyone has had this problem or can help me out, I'd appreciate it.

Bill

I've been experiencing the same problem. I recently had a U joint replaced and the tranny fluid changed on my 1992 F150 4.9L manual. Since then I've had it pop every time I turn the ignition to ON even before I start it. I jiggled the wires underneath front to back hoping I could at least get it to stop tripping for a bit so as to least diagnose where the problem was, but no luck. I mention the tranny fluid because I'm pretty sure the speed sensor is down there. Haven't turned on my radio or nothin since the fuse started popping. I've been using my GPS as a speedometer, but would really like to fix it!! I've gone through 3 fuses troubleshooting. Help.

Something else that is funny: ever since I bought the truck (14,000 miles ago) my dome light has been flickering whenever I push in the clutch to a certain point. I've gotten good enough with it I can keep the light on. I read elsewhere that the screws on the dome lights can be a bit long and short out. So I adjusted those... No go. But that probably wouldn't fix it considering the light flickers depending upon where the pedal is in play zone, and not even when it's engaging, as in the truck starting to move. It flickers while still at a stand still. It's never caused any trouble (accept for when you're backing up at night and you get blasted with the dome light in your eyes), but it could be related.

We've had a couple long camping trip drives and no A/C in SoCal. Being as hot as it is here, I'm sort of afraid something might have melted. I still run the air even when in traffic as is spews out hot air, because Ford says the vehicle is designed to have it on/open. But the dash gets pretty hot, especially near the radio. Could it be a speed sensor problem. Help!

Additionally: no power mirrors, no buzzer chime module (or at least it's never worked), no keyless entry (of course... its a 92). The fuse panels says speedometer memory and radio memory, too.
