Fuse blows, ABS light comes on, A/C stops blowing cold.
I'm trying to help a co-worker who is having a problem with his truck. He has a 2006 supercab F150 with the 4.6 liter. A 15 amp fuse in the passenger kick panel fuse box blows about once or twice a week. He has been replacing it for the time being, but now wants to find and fix the issue. When the fuse blows, the ABS light comes on and the A/C stops blowing cold. Before I start pulling relays and chasing wires, I was wondering if this is a common issue with a common fix. Thanks in advance for any advice.

Which 15 amp fuse is it??? Can you identify the fuse number from the owners manual?
This way we can identify (or you can) as to what circuits are on that fuse, and begin troubleshooting there (looking for a shorted wire on any of the circuits which are protected by that fuse).
Could it be that your buddy spliced some accessory to that circuit? Again, if you can identify which fuse number that 15 amp fuse is, we can help.

And DO NOT INSTALL A LARGER FUSE RATING IN THAT CIRCUIT!!!! You could cause one of the circuit(s) to overheat the wiring and start an electrical fire.

OK, so it's fuse 14. In my truck, there is a 10 amp fuse in that slot. Don't know why there was a 15 in his, but he tells me the dealership replaced the fuse after it popped (he didn't even know where the fuse box was when he asked for my help). I assume the dealership upped the amperage hoping that it would keep it from popping again. VERY bad idea. So, has anyone else lost fuse 14? If not, I'll be chasing wires tomorrow. Thanks.

Tearing my hair out. The trouble is, it doesn't blow every time the fuse is hot. It takes a few days each time, so I can't even chase wires to find the problem. Frustrating...

Ask him if he has changed anything electrical recently. In my last truck (04 ranger) I had a fuse blow everyday. It was the fuse controlling all of the dash lights, so I basically drove around in the dark for months. After days in the heat tracking wires I discovered it to be a LED that I had installed into the havoc controls. For whatever reason it was sending current backwards and popping the fuse. Goodluck on your search man, I know it's a pain.

Darn. Truck is bone stock with no electrical modifications. Without being able to reliably get the fuse to blow, I can't chase wires, so it looks like I'm going to have to send him to a mechanic. Sucks. Usually I'm pretty good at solving automotive gremlins, but this one just requires too much time.

I know this is a long shot from a thread so long ago, but I am having the same issue with my 2005 f150. Did you ever get an answer? I've blown 3 fuses *edit on Circuit 14 *end edit* using standard 10A fuses in the last week. It will work fine for a day or so, but always seems that when it goes it is during startup. Not during driving.
