Question
I just need a picture for the fuse box under the dash for my moms 1991 Cadillac Coupe Deville so we know what fuse is for the horn. That it. Her fuse box does not have the cover to it so we have no idea and I have been on the net for like an hour and a half trying to find one and now have a migraine headache. Please help me.  

Answer
Hello,


Unfortunately, I do not have any iformation that old, and because the car is 20 years old, something like just a fuse cover is probably not going to be found on the web, it could turn into a headache.

However, I have some suggestions that mayhelp you.

The information you need is also in the owners manual. I have seen owners manuals selling on Ebay for $10.

You could go to a junkyard and get either a fuse cover or an owners manual. The years that should be the same are 1990, 1991, 1992 and 1993.

If you intend on keeping the car and want every type of diagnostic information for the vehicle, you can get a subscription to http:// www.alldata.com for about $25 a year and download every factory manual and you can access that information for a year.

I make no money for plugging that site. It is just where I go when I need information on a specific vehicle.

You did not state the reason for knowing where the horn fuse was located. Sometimes they are seperate, but more commonly the horn will be on the same circuit as the dome/ cigarette lighter.

If you have a test light you can determine if power is going to the horn by having someone push on the pad while you are checking power at the horns. If you have power there you have bad horns.

A bad turn signal switch inside the steering column could be the problem. Very common probls were horn pads (air bag).

If you press on the horn pad and just hear clicking, the problem is not a fuse.

I hope my answer helped you. If so please rate it.

Thanks
