Fog/Driving lights
Hi,
Has anyone had fuse blowing problems when turning the switch on for these? When I go to turn on my front and/or rear fog lights they will go on once and then the next time the fuse blows. I always replace the fuse with the correct AMP as labelled. Is this a problem others have had? Should I go up 5 AMPs?
Thanks

DO NOT INCREASE THE AMPERAGE OF THE FUSE! that will fry your system. The fuse is there so you don't fry your system. To me, it seems that you have a short somewhere in your system that could be due to a faulty fog light bulb fixture, or one of the wires is grounding to the chassis which is causing a short. You will have to look into the whole system yourself to see where the short is before you will be able to fix it.

dangillo. odds are your problem lies in the headlight switch. The other possibility is if you have upgraded your fog lights to HID bulbs. The ballasts can pull a lot of current when starting and I have seen where certain ones will pull enough current that after a few starts, it will weaken the fuse and cause it to open on the following start. Keep in mind that each HID bulb will pull about 20 amps on start up (40 amps total) on that 15 amp fuse. The fuse will take it, but after awhile it will weaken and result in the fuse blowing.
As for going up in the amperage rating, I would not recommend that. The wiring is truely only rated to handle sustained currents for a finite amount of time. Most car wiring is borderline too small as it is. You start upping the fuse, you are going to allow more current to flow, resulting in the possibility of having BBQ'ed Jaguar (ie, electrical fire). Last time I checked, that does not taste too good. So, unless you are upgrading portions of the wiring to your car, I do not recommend changing the size of the fuse.

dangillo, I would start with simply unplugging the headlights themselves and then attempting to turn on the headlights. If the fuse still blows, then you know the problem is internal to the wiring of the car. From there you can pull the fuses to the items in question and half split the wiring that way. If the fuse doesn't blow with the headlights removed, then install 1 of the headlights and turn on the headlights. If the fuse blows, then the headlight you just plugged in has the issue. If the fuse doesn't blow, then odds are the other headlight is the one with the issue.
