Let me start by saying that I'm an electrical newbie and do not know much, if anything, about electrical systems.
This is not an install or an add-on type problem but I thought with the wealth of knowledge on this forum that someone might be able to help me with my problem.
I have a 2005 Ford F-150 and my dash lights went out on me the other night. I was driving and I just happened to notice that they went out. I don't think anything out of the ordinary was going on and I know that nothing of an electrical nature had been modified in the truck. My guess was that the fuse was blown so I finally got around to changing it today but because it was light outside it was hard to tell if the dash was lit. I discovered tonight that the fuse had blown again so I changed it again and it must have blown immediately because the dash never lit up.
What would cause this to happen? Could it be a bad ground connection? I know whenever I get out of my truck I get a shock. Maybe the two are unrelated. Any ideas or suggestions?
Thanks in advance for the help.
Michael

It could be a short or blown bulb anywhere in the parking light circuit, so the corner lights/tail lights as well as the dash lights.

Thanks for the suggestion, but I have a follow-up question: If a light in the circuit was out wouldn't that not complete the circuit and thus not draw any electrical power, let alone enough power to blow the fuse? Thanks.

I checked the other lights and they are all fine. According to the manual the instrument cluster is the only thing supported by that fuse (5A).

I have a ford escort and i found that my stero was grounded to the illumination cable when that happens the dash light  fuse blows so i suggest if you have just fitted a new headunit then look at the wireing. I also had this problem with a friends ford KA after i regrounded the headunit there has not been a problem since.

I hope this helps Dash Light Fuse Keeps Blowing -- posted image.

Thanks the_DJ

I do have a aftermarket headunit. I pull it, change the fuse and see if it still blows without the stereo in the vehicle. Thanks.

Got an alarm? I have seen people including myself connect to the wrong wire for parking light flash and blow out the dash lights.
